    PROFINET is the open, cross-vendor Industrial Ethernet standard for discrete and process automation. There are many choices of ways to add PROFINET to an automation device that it can seem daunting to know where to start. The starting point depends on the type of product, its existing design, quantity expected, and time to market needed. This page focuses on the on the development and integration of PROFINET products and their certification. It covers four main sections that guide device manufacturers through the process of making their own PROFINET device:

    Product Development Cycle

    Product Implementation Options

    Solution Providers

    Testing and Certification


    Additional Resource: PROFINET Community Forum

    Product development cycle

    Every device development project undergoes a product development cycle. An example of this process for PROFINET is presented here. It includes four main stages.




    Integration of an industrial communication interface into an automation device begins with information gathering to determine the functionality of your industrial networks along with familiarization about the task at hand. PI itself, as well as a number of its member companies can provide you with comprehensive information here. Advice is available from various PI Competence Centers, solution providers, books, brochures, seminars, and Developer Workshops for getting to know PROFINET.

    Individual consulting services support you, as a manufacturer, in every phase of implementation. Here are some typical questions:

    What benefits does PROFINET offer for my products?

    Which features (Conformance Classes) must be implemented for the product?

    What technologies and support are available for implementing PROFINET?

    Development proceeds faster to our goal if we don’t have to reinvent the wheel. In order to bring PROFINET into automation devices quickly and efficiently, the expertise of PI members on the following topics is available:

    Development environment: A variety of starter kits and evaluation boards are available for almost every implementation method. These complete sets enable a quick introduction to development activities and often contain a complete development environment.

    Implementation options: Depending on the functionality required (Conformance Class), it is essential to select the suitable type of implementation for each individual case. The available development capacity, company expertise, expected costs to produce the interface, and the time to market also play a large role.

    Hardware/software design: The plan of action and expenditure required for hardware and software design depend heavily on the selected implementation method. Here, you can carry out the development work independently or work collaboratively with a development partner.

    Device description file: To enable fast and easy configuration of an automation system, manufacturers of field devices must provide a PROFINET device description file. This so-called "General Station Description file" (GSD file) contains all the information needed to configure a device. The GSD files for PROFINET are XML-based and enable multiple product variants and different languages to be captured in one file.

    Service & Support


    Once your device is certified, it is now ready for the market. Make sure your package is complete, including sales literature and web presence. Also, make sure your sales force thoroughly understands the product. GSD files should be included in your package, or preferably made available over the Internet.

    You may have your own routes to market, but PI can help you with:

    • A member-maintained on-line product database at
    • Electronic newsletters such as PROFINEWS with large distribution lists which can be used to promote your product and generate sales leads

    These services are free to members. Your local Regional PI Association office (that’s us in North America) will also be able to help by offering the chance to advertise and to exhibit at regional events. The advertising and exhibiting opportunities in North America are detailed here. Most of these are excellent ways to meet new customers and to network with like-minded PROFINET people.

    PROFINET communication in industrial plants is based on IEC 61158 and IEC 61784. In addition, IEC 62061/ ISO 13849-1 apply to safety modules and devices. To ensure interoperability and conformity of automation devices from different manufacturers, device certification by an accredited PI Test Laboratory (PITL) is mandatory for PROFINET. Even though every PROFINET device must be certified, the effort required for successful certification varies depending on the technology used.

    For you, the manufacturer, certification is as easy as can be: The fully developed PROFINET device is tested by an accredited test laboratory. After successful testing you, the manufacturer, can apply for a certificate from the PI, using the test report as a basis.


    Implementation options

    Device manufacturers wanting to equip an automation device with a PROFINET interface have different options for implementation. Before deciding on a specific implementation method, it’s important to first determine which functions are to be supported by the PROFINET automation device.

    Real-Time Requirements

    IEEE 802.3 ensures problem-free communication between PROFINET automation devices and among PROFINET automation devices and other standard Ethernet devices. For applications with very stringent real-time requirements, PROFINET offers mechanisms that enable both standard and real-time communication to take place in parallel. Communication with PROFINET can, therefore, be scaled using three different performance levels, which build on each other:

    The transmission of engineering data and non-time-critical data occurs over TCP/IP. This standard communication is possible between all automation devices.

    The real-time (RT) channel is available for the transmission of process data.

    For isochronous applications like motion control, Isochronous Real-Time (IRT) communicatio is used. This enables a clock rate of < 1 ms and a jitter of < 1 µs. IRT capability is based on hardware support in the device.


    Conformance Classes

    To meet the different requirements of automation systems, three Conformance Classes that build upon one another are defined for PROFINET. Each class has a functional scope determined for the typical area of application.

    CC-A: CC-A includes the use of existing Ethernet network infrastructure, including integration of basic PROFINET functions. All IT services can be used without restriction. Examples of typical applications are found in building automation and process automation.

    CC-B: The functional scope of CC-B comprises the functions of CC-A plus support for user-friendly device replacement without the need for an engineering tool. Furthermore, Simple Network Management Protocol (SNMP) supports extended device diagnostics of network functions, such as port status messages.

    CC-C: The functional scope of CC-C comprises all the functions of CC-B plus it supports high-precision and deterministic data transmission, including isochronous applications. The integrated optional media redundancy enables smooth switchover of I/O data traffic if a fault occurs.

    conformance class2

    Implementation Options

    Depending on the Conformance Class required, different types of implementation are available for each individual case.

    In principle, the following options are available:

    1. Standard microcontroller unit (MCU) with integrated or external standard Ethernet controller or FPGA
    2. FPGA with internal or external standard or IRT-capable switch
    3. Module with standard microcontroller or with microcontroller with IRT hardware support
    4. ASIC with IRT hardware support and IRT-capable switch
    options dev

    CC-A and CC-B provide the possibility of implementing a single-port interface. However, the economic viability of the solution should be taken into consideration. Including a two-port interface (integrated switch) can be beneficial for customers seeking to implement a line topology in their network.


    development paths

    Individual design

    The implemented PROFINET interface is embedded in a hardware and software design that has been optimized with regard to development expenditure and time to market using commercially available software solutions and standardized discrete or FPGA-based hardware design schemes.

    Communication module

    The implemented PROFINET interface is embedded in a design that has been optimized for flexibility and time to market-based on preassembled commercially available communication modules.

    External couplers

    With this solution, the PROFINET interface is implemented without accessing the device electronics based on external couplers and using an adapter connected in series.

    Each of the implementation methods can be realized in a different way. When selecting the most suitable method for the particular case in question, the expected production costs, the development time, and the resulting time to market must be taken into account.


    Solution providers

    The advantage of collaborating with an external development partner when developing a PROFINET interface is that the product manufacturer can concentrate on its core areas of expertise. This reduces development risks and time to market. The experience of external specialists helps to ensure that the design of the automation device is competitive and technically feasible with respect to its communication technology. This section offers a list of solution providers in North America.


    Robust and reliable PROFINET network interface

    Analog Devices is the leading global high-performance analog technology company dedicated to solving the toughest engineering challenges. We enable our customers to interpret the world around us by intelligently bridging the physical and digital with unmatched technologies that sense, measure, power, connect and interpret. Our extensive experience with industrial communication and our commitment to industry have led to the development of the RapID Platform Network Interface – a complete, cost-effective, and easy-to-integrate PROFINET connectivity solution.

    The RapID Platform network interface manages the PROFINET protocol and network communication for a host processor.

    The network interface can be integrated as a module or embedded circuit. It contains everything needed for star, line, and tree network structures, including the communication controller, protocol stacks, Flash memory, RAM, Ethernet switch, and PHYs. The two Ethernet connections can be connected to any PROFINET network. A UART interface, SPI, I2C or std. Ethernet interface can be used for the connection to the applications processor. On the software layer, the host processor is connected to a "Unified Interface" so that other industrial protocols can also be used without having to change the software of the host processor. Thanks to the PriorityChannel® technology of Analog Devices, the network interface has earned PROFINET v2.3 certification for Class B and C devices as well as Net Load Class III approval System start according to v2.2 and v2.3 are both supported so that your field device functions problem-free in any PROFINET network.


    Easy hardware and software integration

    As a module, the network interface solution can be easily integrated into your own designs. You simply connect a power supply/ground/reset and connect the host processor to selected host interface.

    For development of customized circuits, the hardware of the network interface can be integrated based on circuit diagrams contained in the scope of delivery. The scope of delivery also includes the bill of materials and example circuits in order to minimize the hardware development costs. Software for development of customer-specific circuits is provided in the form of firmware, which is downloaded to the Flash memory on the printed circuit board. There is no license fee or user fee, regardless of whether you use the module or an integrated circuit.

    Software can also be easily integrated in a host processor. Messages are exchanged between the host processor and the network interface on the basis of a "Unified Interface". A tool provided by Analog Devices that is designed to run on a PC is used to configure the network interface so that you can adapt the necessary parameters of the field devices. The tool also facilitates the adaptation of the GSDML sample file supplied by Analog Devices to your field devices. An additional function of the Unified Interface ensures that the software of the host processor does not have to be changed when PROFINET network parameters change or a different Industrial Ethernet protocol is used. A component of the Unified Interface is a "socket" interface that supports direct Ethernet communication. The scope of delivery includes sample C code so that you can quickly establish a connection between the host processor and the configured network interface

    Reliable and flexible network integration

    The network interface enables reliable PROFINET communication in conformance with Class B and Class C. PriorityChannel® technology – available only from Analog Devices – is used for this. It eliminates the effects of the network traffic and ensures reliable real-time behavior of the network in accordance with Net Load Class III. This technology provides a significant competitive advantage for your devices, extremely low jitter, and a reliable connection, which will not be disconnected even at a network load of over 95%.

    PROFINET support includes optional support of isochronous communication (IRT) the Discovery and Configuration Protocol (DCP) for configuring field devices, and the Link Layer Discovery Protocol (LLDP) for topology management. The scope of delivery also includes the Simple Network Management Protocol (SNMP) and the required Management Information Bases (MIBs) that are used for network configuration and diagnosis. To make commissioning easier, the solution includes a dynamic web server. You can use this web server to create web pages for your field devices that can be displayed on a standard web browser. The network information and real-time parameters of the relevant field device can be updated dynamically at any time on the web page.


    Fast integration

    The starter kit for the RapID platform network interface enables fast analysis of the circuit for connection of a host processor to the network interface module. The scope of delivery includes an application example that demonstrates the end-to-end communication, i.e., the communication between the host processor and network interface and controller. The Evaluation board allows to connect a host application board on the bench. As soon as communication has been established on the host processor side, the PROFINET communication can be tested with a PLC or controller simulator. This communication can be thoroughly checked before the network interface is integrated in the circuit of the field device.

    One of our stories

    Analog Devices, a global manufacturer of semiconductors, wants to expand its portfolio of multiprotocol Ethernet switching chips. The goal is to provide even broader support for the PROFINET industrial fieldbus protocol and the associated product certifications. This required profound expertise in existing solutions and standards as well as bleeding-edge technologies.

    Our collaboration included supplementing PROFINET with isochronous real-time (IRT) support for existing hardware. In this case, we worked closely with our customer to analyze integration options and expand the existing code basis as needed. Key factors in the success of the product certification were the excellent collaboration with Analog Devices, coordinated test runs, our extensive device base, and our PROFINET certification expertise. We also needed to demonstrate how the future PROFINET-over-TSN concept can be integrated in a new switching chip generation. We did this by implementing the first-ever integration of a PROFINET-over-TSN-capable stack on Analog Devices’ new hardware generation.

    HMS Industrial Networks - Connecting Devices

    HMS is the leading independent supplier of products for industrial communication, with the product brands Anybus®, IXXAT® and eWON®. HMS products make it possible for industrial machines and devices (hardware) to connect with control systems and Internet (software). Our motto, Connecting Devices™, provides the foundation for realizing the full benefits of Industrial Internet of Things. If you want to connect “Things” to the Internet, you need solutions that enable communication between the hardware and software. This is precisely what HMS offers.


    Why it is time to move to PROFINET

    The HMS Networks Market Share 2018 report displays that PROFINET has taken 12% of the industrial communication market due to multiple factors. Firstly, PROFINET is built on Ethernet allowing it to support a high node count, faster data rates and larger data packets. It also has the flexibility to be used over a variety of media such as wired coppers, fiber optic cables, and on standard 802.11 wireless connections. This does not require any proprietary wireless adapters, enabling you to mix and match sup­pliers.

    Commissioning a PROFINET device is easy due to plug and play nature of the network. PROFINET devices use auto-negotiation to query and determine the speed and duplex mode of the network. Currently, these parameters are 100Mbps full-duplex. PROFINET devices can also contain one or two Ethernet ports. Devices with dual Ethernet ports have a built-in switch that allows you to daisy-chain other PROFINET devices on the same line. This line topology is like the standard bus topology found in PROFIBUS and can reduce wiring costs compa­red to a typical star topology. With the combination of the topology discovery feature and other IT features, you can map out your network and have a visual representation of your network topology. This feature allows much quicker diagnostics and can be used to visualize incidents such as wire breaks and loss of communications. Furthermore, this topology does not require the use of additional swit­ches, reducing overall costs.

    Through Anybus® CompactCom™, you can give your industrial device PROFINET network capability with various physical form factors. Available in Chip, Brick or Module form factors, our cutting edge CompactCom 40 series is based on our award-winning Anybus NP40 network processor. It is ideal for both general purpose and for high-end PROFINET-IRT applications with fast network cycles and synchronization demands. Overall, implementing PROFINET is a great way to ensure your device’s continued success and HMS Industrial Networks is with you every step of the way. Thanks to the help and support of PI (PROFIBUS and PROFINET International), we predict that ­PROFINET will continue to meet the needs of the automation marketplace and we are creating solutions to help device manufacturers to stay connected.

    Testing & Certification

    This section describes how testing and certification work, how to prepare for testing, and how to get a product certified. Also, this guide contains suggestions and resources to complete the certification process with ease.

    Getting Started

    Certification is the process by which a PROFINET product is tested in a PITL for conformance and, upon successful completion of the testing, issued a certificate by PI.

    Products are certified to verify the correct behavior of communication according to IEC 61158 and IEC 61784. Specifically, PROFINET devices are tested for the correct implementation of the following items:

    • Hardware interface
    • PROFINET mandatory and optional functionality
    • Reaction on faulty behavior
    • Robustness against netload
    • Proper operation in a reference automation environment
    • State machines
    • GSD file

    The PROFINET IO Test Bundle contains a “PROFINET Versions for Certification” document. This document lists the current PROFINET specification and GSD versions. It also indicates the certification testing validity dates for specific versions. The PROFINET IO Test Bundle is available to members at:

    Passive components include infrastructure components like switches, cables, and connectors, and do not require certification. An exception would be if a switch also functions as a PROFINET device, and has its own GSD file, in which case certification is required.

    For passive PROFINET components the conformity must be declared by the manufacturer of the product. These products can then be added to the list of PROFINET Passive Network Components posted on the PI website.

    Brand labeling occurs when another vendor resells a device without any change of hardware or firmware.

    Brand labeled PROFINET devices need a unique Vendor ID and an updated GSD file. The brand labeling vendor can apply for a certificate based on the original device manufacturer’s test report simply by adding a Manufacturer’s Declaration. The Manufacturer’s Declaration is available upon request from the PICO.

    Certification is mandatory for PROFINET devices and controllers. Each product must be certified according to its Conformance Class. Also, some additional PROFINET features, such as the PROFIsafe and PROFIenergy Application Profile, require certification. The table below summarizes the certification requirements:

    PROFINET GSD files are written in XML format (therefore sometimes also called “GSDML files”), and they describe a PROFINET device’s functionality. The contents of the GSD file consist of configuration information, parameters, modules, diagnostics and alarms, and vendor and device identification. For certification, the device manufacturer must provide a GSD file for each device.

    PROFINET allows for several optional features such as Media Redundancy Protocol (MRP), Isochronous Real Time (IRT), or Fast Start-Up (FSU). If a device supports them as defined in its GSD file, then these optional features must also be certified to verify compliance.

    PI does not allow product self-certification. PROFINET components must be tested at a PITL and certified by PI before product launch.

    A product certificate shows compliance of a device manufacturer’s product, such as an IO, sensor, drive, or encoder. The certificate proves a device has passed all testing according to the PROFINET standards.

    A technology certificate certifies the compliance of a reference design (solution), usually in form of a development or evaluation board, that implements the PROFINET protocol inside a device manufacturer’s product. The chosen solution might be, for example, an ASIC, software stack, module, or plugin board. This certificate shows that the solution intended to be used in the PROFINET device is certifiable according to the PROFINET standards.

    Companies that are not members in PI can purchase the PROFINET specification:

    Besides technology specifications, PI offers many free and paid documentation and resources. The following are some commonly used (member-only) development resources:

    • PROFINET IO Test Bundle
    • PROFINET GSD Checker
    • Application Profile Specifications
    • Test Specifications

    PI members have full access to all standards, guidelines, specifications, software, resources, and documentation at no charge. PI members can obtain the PROFINET specification at no-cost as a membership benefit. Upon joining PI, members are issued a company-wide login with rights to these downloads. The full PI documentation and resource list is available at the PI download center:

    All PROFINET components have two associated IDs: A Vendor ID and a Device ID. Device manufacturers must obtain a Vendor ID and define a Device ID before testing since both IDs are included in the device’s GSD file.

    Vendor IDs are unique, and therefore managed and assigned by PI to each company. Device manufacturers can obtain their PROFINET Vendor ID at no charge by sending an email to: certification{AT} Vendor IDs are the same for PROFIBUS, PROFINET, and IO-Link. If a device manufacturer already has a Vendor ID for PROFIBUS, there is no need to request a new one for PROFINET.

    The Device ID is chosen and managed by the device manufacturer. Each device should have a unique Device ID specifically for the device. The “GSDML Technical Specification for PROFINET” document in the PROFINET IO Test Bundle contains details about Device ID formatting.

    Since the PROFINET specification is open and standardized, anyone can build and sell PROFINET products; a PI membership is not required. However, joining the membership is beneficial, especially during the development process. The affiliation gives members access to the aforementioned downloads along with cost reductions for training and certificates, among other benefits.

    Companies become a PI member once they join an RPA. Companies can choose to join multiple RPAs since each RPA offers unique local marketing and training opportunities. PI North America is the North American RPA. Among other benefits, PI North America members can participate in comprehensive marketing programs. To join PI North America, an application form can be submitted at:

    Before Certification Test

    The same tools and software used by PITLs for testing are also available for free to PI members as part of the PROFINET IO Test Bundle.

    The PIC also offers a “pre-test”, an abbreviated test that covers the most critical parts without going in depth. The result indicates a list of issues to resolve before the actual test. The pre-test is recommended for first-time applicants or new/complex devices.

    To begin the process, the device manufacturer must fill out and sign the standard test application form. As part of it, they must specify all supported application types, features, and Application Profiles. The PIC test application form can be found at:

    It is also recommended to send the device’s GSD file together with the completed test application form. Based on the completed test application form and GSD file, the test length and cost can be calculated. Then, the PIC can provide a quotation if required. The final step to book the test is to send a Purchase Order (PO). Once the PO is accepted, the PIC will schedule and confirm the test date based on the device manufacturer’s requirements and the PIC’s schedule.

    The length and cost of testing depend on the supported features, device complexity, variants, and other factors. For example, a simple device takes about three days of testing; a complex device family can take up to two weeks.

    The PIC test application form includes a fee schedule as an initial estimate. The PIC can provide a final quote after receipt of the completed test application form and associated GSD file.

    The information provided in the completed test application form will be reflected in the eventual test report and shown on the official certificate. The device manufacturer should submit the completed test application form in their name, even if they work with a third-party developer. The manufacturer can also choose to endorse a third party allowing the PIC to work with a third-party developer during the test. The PO can come from either party.

    As a recommendation, the device manufacturer can start the application process as soon as they can forecast the end of development or internal testing. The PIC test application form contains a field to specify the “earliest test date”.

    Lead times in the test lab depend on lab availability and vary from ‘immediately’ to several weeks out. Device manufacturers can obtain the current lead time by contacting the PIC directly.

    The customer must contact the PIC immediately when schedule changes arise. The PIC coordinates closely with device manufacturers to reschedule test slots.

    Testing a PROFINET controller is similar to testing a PROFINET device. The test application form has extra fields to provide controller-specific information. The PIC offers a controller test information bundle which will be provided after receipt of the completed test application form.

    During Certification Test

    It is possible to certify several “variants” of a device along with the representative device. Variants usually differ in terms of application features (number of IO modules, etc). The variant list must be included in the completed test application form.

    While not required, it is recommended that a representative from the device manufacturer’s team attends the test for the first one or two days. Having a representative on hand helps to quickly resolve issues that arise during testing. If issues cannot be resolved, the representative can learn to reproduce the issues outside of the test lab. This is especially true for customers completing their first PROFINET project or submitting a complex device for testing.

    Once the device has passed the testing, the PITL sends an accredited test report to the device manufacturer.

    It is important to know that PITLs do not issue certificates directly. The device manufacturer will use the test report to apply for the actual certificate from the PICO.

    After testing, the PIC can send the device back to the device manufacturer. The device manufacturer must indicate a carrier account number on the completed test application form or send a prepaid shipping label with the product.

    If the device manufacturer does not need the device back, the PIC will repurpose and add it to its integration test network to use in future tests and to showcase the variety of devices available.

    The PIC provides the following power supplies in its test lab. If the PROFINET device requires additional power supplies, they should be sent along with the sample device for testing.

    • 24VDCforcurrentdrawupto10A
    • 120V/60HzAC1Pforcurrentdrawupto10A
    • 240V/60HzAC1Pforcurrentdrawupto3A
    • 230V/50HzAC1Pforcurrentdrawupto3A

    The PIC can supply the following network cabling in its test lab. If the PROFINET device requires additional cables, converters, PoE or interface types, they should be sent along with the sample device for testing.

    • RJ-45 / 4 conductor
    • RJ-45 / 8 conductor
    • M12 / D-Coded / 4 conductor
    • M8 / D-Coded / 4 conductor

    Normally, sending one device for testing is sufficient.

    If there are several variants, the PIC and device manufacturer will discuss before the test which ‘main devices’ (full test) and ‘variants’ (partial test) require testing. Usually, not all variants need to be tested.

    Also, even with just one main device, it can be beneficial to send more than one device. For example, some tests can run in parallel, or the testing can continue if one device locks up.

    The best option is to supply the PROFINET interface component along with a system simulator that runs a full implementation of the application software without the large, heavy, or power- hungry physical apparatus.

    Another alternative to certify the device is to inquire about on-site testing services. For example, PITLs are allowed to perform an on-site test if the device meets one or more of these criteria:

    • Device or any device part exceeds the maximum transport size of 1800 x1500 x 700 mm
    • Total transport weight of the device is greater than 300 kg
    • Device utilizes or is technically possible to adapt it to utilize input power higher than 32 A, 400 V AC, 50 Hz, or corresponding values for countries outside Europe

    Each PITL has different strategies when reporting issues with a device during testing.

    For example, the PIC will report minor issues back to the device manufacturer as they happen while continuing to test other aspects of the device. Once the PIC receives a fix, they will verify the issues are resolved. For major issues (hardware/performance/stack issues), the PIC can put the test on hold and resume after receiving the updated device.

    The certification test should not be seen as a pass/fail test. The PIC and the customer have the same goal: to have the device successfully certified.

    After Certification Test

    After testing, the device manufacturer will receive a test report from the PITL. To obtain the certificate, the device manufacturer must send the positive test report and a completed certificate application form to the PICO:

    The certificate costs 1800 EUR for PI members and 6000 EUR for non-members.

    The granted certificate is valid for three years. It can be prolonged if specific criteria are met.

    The Product Finder on is a central repository where end-users search for PROFIBUS and PROFINET enabled products. As a member benefit, PI members can add their products to the Product Finder.

    It is the manufacturer’s responsibility to add and update their product information.
    To add new entries to the Product Finder or edit existing entries, members must log in to:

    The rights to use the Association Trademark and Technology Trademarks are acquired through membership. Member companies can use these logos as part of the marketing of their products or simply to display support of PI’s technologies.

    The Certification Trademark can be used to identify products certified by PI. The right to use the Certification Trademark terminates automatically if the product is modified and no longer satisfies the established test criteria.

    The device manufacturer can request to prolong the validity of a certificate. The request must be made within three months prior to, and three months after, the certificate‘s expiration date. For this purpose, the device manufacturer must send a completed certificate application form and a Manufacturer’s Declaration to the PICO.

    The declaration must contain the following statements:

    • Declaring the unchanged conformance of the product with the tested prototype in hardware and software per the latest test report.
    • Declaring there is no newer version of the device that uses the same device identification, i.e., Vendor ID, Device ID, or DAP-Module-ID.

    Otherwise, the prolongation of a certificate requires a retest.

    Device Manufacturers can update a GSD file to a new version by ensuring compatibility with the old version under their own responsibility. Then, the device manufacturer must submit a statement directly to the PICO. In any case, the device manufacturer is responsible that at any time, only one valid GSD file exists for a product. If the device manufacturer wants to update their certificate with a new GSD file name, they must contact the PICO to obtain an updated certificate.

    Product modifications invalidate the certificate. Depending on the modification, the PICO can update the certificate via a Manufacturer’s Declaration, a new test report, or a positive statement from a PITL.

    Some product changes only require a Manufacturer’s Declaration; other modifications require partial or full retesting. For example, changes in the communication interface or firmware modifications require retesting. Contact a PITL to assess the retest requirement.
