How to Communicate with Ethernet XT Profinet from Siemens S7-1200 PLC Application Note

EthernetXT Profinet and Siemens S7-1200

When setting up a Profinet network, Profinet controllers are programmed with a special Profinet Configuration tool, like the Step7 from Siemens. This document illustrates an example procedure for configuring communications between Acromag BusWorks® Series Profinet modules and a Siemens S7-1200 Programmable Controller. It is assumed that the user has a working knowledge of the Siemens TIA Portal environment, ladder logic programming, and the S7-1200 hardware. TIA Portal V11 is used for illustration purposes. At this point, it is assumed the user has already created a project and installed and configured an S7-1200.

Installing the GSDML File

The process of configuration of Profinet devices is based on electronic device datasheets, or GSD files specific to the device. This file defines the electronics of the device and its relevant communication parameters to the network IO Controller or Supervisor. This file is formatted in GSDML (Generic Station Description Markup Language) and it describes the implementation of a Profinet device to another device on a Profinet network. Note that GSDML is a combinational acronym taken from its language XML (eXtensible Markup Language) and its function GSD (General Station Description).

Communicating with Ethernet XT Profinet From Siemens S7-1200 PLC

The first thing we want to do is install the GSDML file for our example device into the PLC.

  1. From the options tab, select “Install general station description file.”
  2. Next, select the GSDML file you wish to install.
    You may need to use the “Browse” button to the right of the “Source path” in order to set the path to where your GSDML files are located. Be sure that the associated image file is in the same directory as the GDSML file.
    When ready, click “Install”
