Communications between Profibus DP Slave Wireless Gateway (105U-G / 905U-G) and Siemens S7300 PLC 2019s
 |
BACKGROUND
The 905U-G-PR1 acts as a Profibus DP Slave - the network host a Siemens S7–300 PLC is a Profibus Master. If using is a 905U-G with a PLC, the PLC will require an Anybus GSD file so it can recognize the Profibus interface in the 905U-G. This file loads into the PLC. The file is available on the same CD as the configuration software or from the Elpro web page www.elprotech.com
Configuration of the Profibus data bus comprises of allocating a Profibus Slave address to the 905G, and configuring links between the I/O registers and the Profibus bytes in the Anybus Interface module.
