Is that ET200m family part of the Siemens brand?

Et200m

hello,

when you use Step7 you don't need other tools. ET200M are S7-300 modules with IM for profibus.

Hello Hosein.

You need to understand how your PLC manages Profibus DP Slaves. There is a configuration tool for each PLC brand for this purpose.

If the PLC in question is not a Siemens S7, then you will need to import the GSD file for the ET200M into the configuration tool.
You can download the GSD file from Siemens website: http://support.automation.siemens.com/WW/view/en/113498
