I have 80 VFDs in my chemical factory and always break down every now and then. I am thinking to form a system as said below.
Connect all the VFD to PLC. there will be HMI and DCS. The I/O modules of PLC will be connected to the DCS thru Fibre optics due to distance.
MODBus TCP/IP -> to fibre optic converter (converts signals to FO and again FO to signals) -> MODBus TCP/IP DCS.
My qn is other than fibre optic converter, what are the components required for this process?
