PROFINET Basics


PROFINET Device Names

What’s the MAC address of the device you are viewing this from? The IP Address? What’s your name? The easiest of all those to remember is your name, mine is PNC for short. PROFINET device names are used for the same reasons.


PROFINET Naming Convention

The number one rule-of-thumb, which you should never forget when commissioning a PROFINET system: make sure to assign the device name from your engineering tool (or setup auto commissioning). Here is the PROFINET Naming Convention list to help you out.


IP Addresses

An oft-heard question: “Why do PROFINET devices need IP addresses? PROFINET uses names!” You may have heard the misinformation that PROFINET does not use TCP/IP. The correct information is that it in fact does.
So, the short answer to that oft-heard question: PROFINET uses TCP/IP and therefore needs an IP address.


PROFINET Device Parameters

PROFINET device parameters are features that can be selected to set the operating conditions of a device. PROFINET supports 3 types of parameters: Standard parameters, F-parameters, and Dynamic Parameters. The GSD file of each device defines its parameters (GSD files are explained in PROFINET GSD File Basics). Three Types of Device Parameters 1) Standard Parameters Standard parameters are available for each device.  The PROFINET Controller configuration […]
