APL: Bringing Ethernet to the Field

“The realization of this vision began in 2011, when a group of solution suppliers at the urging of several end user groups began a technical investigation of a protocol-neutral, advanced physical layer (a.k.a., APL) that could solve the longtime problem of a long-reach Ethernet for use in hazardous locations.” APL White Paper Description In order…

Fiber Installation Considerations

PROFINET cable manufacturers offer a range of cable types and classes for different applications, including those with special properties. These cables come in two flavors: copper and fiber optics. This post covers installation considerations for fiber optics cables. Because fiber optic cables do not carry electrical currents or voltages they are totally immune to electromagnetic…

Scalable PROFINET System Redundancy

Redundancy is a requirement in many process automation systems.  Four PROFINET system redundancy configurations have been defined by PROFIBUS & PROFINET International: S1, S2, R1, and R2. First, S or R denotes whether a PROFINET node implements either a Single or a set of Redundant Network Access Point (NAP).  Then, the number following S or R determines the number…

PROFINET Redundant Components

Generally, in an automation network, there are many components that can potentially fail. Depending on the end user’s requirement, PROFINET allows them to build a reliable network according to their specific goals. Specifically, there are four PROFINET redundant components: Media Redundancy, Controller Redundancy, Device Redundancy, and Network Redundancy. Device Redundancy A network with device redundancy has a…

Switches and Ring Topologies

PROFINET offers a variety of possible topologies: tree, line, ring, star, etc. Nearly all PROFINET devices have two ports on them, and behind these two ports, there is an integrated switch which allows the creation of a line topology. Some topologies permit redundant media and decrease the chance of failure. Specifically, PROFINET allows you to…

Six Profinet Highlights

Profinet provides one network for all applications: factory automation, process automation, and motion control. Although, there are many benefits to using Profinet, let’s focus on six of them: Diagnostics During commissioning, maintenance, or when an error occurs, it is necessary to obtain an overview of the plant or machine status in minimum time. The integrated…

Diagnostics and PROFINET Webinar- Q&A

A few weeks ago we hosted a webinar together with the PIC (PROFI-Interface Center) about PROFINET Diagnostics. We had many attendees and several of them had very interesting questions during the webinar. As a recap and a way to sum up most of the questions, we have answered them below. Q&A 1.-Is there a generic…
