Hello!

I have a task in which ET 200s is used. A communication has to be done between ET 200s (using PROFINET port) and SCADA TraceMode, which supports OPC Server and Modbus TCP integrated driver. I am hesitating between 2 options and hope you can help to choose which way is better and more economic.

1. To use OPC by Siemens, which supports Profinet. Could you please recommend which OPC Server is needed for this purpose.

2. To use controller S7-1200, which extracts data from ET 200s via Profinet and transfer that data to SCADA via Modbus TCP (to be used as converter).

I will also accept other possible ideas.
Thank you.

 

It is possible to use also following OPC Server S7 communication:

It can automatically import all variable from S7 project.

Fast and with debug view of communication. Free demo version to download available (30 minutes communication)
