The motor manufacturer company states that it can make motor drivers according to my request. Using the Modbus TCP/IP communication protocol, LOGO! How many motor drivers can it communicate with at the same time and how fast can it do it? Or would it be better to try to do RS232 or 485 communication by supplying a CIM module? LOGO! can it do this job? Or do I have to work with the S7-1200 for this job? Your comments are very important to me.

I'll have to test how fast you can do this job. One second delay is not problem for me. I hope he can do this. If the delay is too much, it will be a problem for me. Because if I have to use S7-1200, I would be making a mistake because I don't use Modbus RTU. I will have to pay additionally for drivers communicating via TCP/IP. This can be an unnecessary investment. Best Regards.
