Hello,
I have some questions about connecting plc to opc via modbus.
The problem is that i don't have serial port on my laptop, there is only ethernet port (ethernet adapter).
Can I connect laptop directly to modbus hub via cat5 cable or i need some device between them?
I'm using Matricon OPC server for modbus, and Schneider's Modicon M238 plc.
Thanks a lot.
