PROFINET Security for Industry 4.0

Security at the Protocol Level In this world of Industry 4.0 and the Industrial Internet of Things, digitalization of production processes is mandatory. As digitalization spreads to all levels and applications in manufacturing, IT security gains more importance. Previous security concepts relied primarily on isolating production plants from external users and networks. But in the…

PROFINET Addressing Parameters

If you are planning on adding new nodes into your PROFINET network, you will need to consider their addressing parameters. Each PROFINET device has 3 addressing parameters: a MAC address, a device name, and an IP address. The MAC address is predefined by the manufacturer, and usually, it can not be changed. On the other…

PROFINET Communication Channels

PROFINET is an open Industrial Ethernet standard. It is a communication protocol that exchanges data between automation controllers and devices. With over 25 million installed nodes (as of 2018), PROFINET is one of the most widely used Industrial Ethernet standards worldwide. But even though millions of users are familiar with PROFINET, not all users understand…

What about Fiber in Hazardous Environments?

Is fiber ok in hazardous environments*? We got this question in one of our PROFINET one-day training classes while explaining APL(Advanced Physical Layer).  Ethernet is not intrinsically safe. Since IEEE 100BASE-TX Ethernet is the base technology for PROFINET, PROFINET cannot reach hazardous environments. There are options to go around this limitation. Some factories employ containment methods such…
