I have a situation where I want to use the MODBUS 485 option of a Gas Monitor Controller. I do not want to use the 4-20mA option as the analog input cards for the series of PLC are discontinued and cost thousands if you absolutely want one.
Currently the client has a CMM321 comms card on the rack that handles the HMI's on the network. This is done with the TCP port on the CMM321 card. The Ethernet cable is converted to Fiber and travels around 300 feet to another building. At this other building is where I will have the gas controller.
Would anyone agree that my best option is to utilize the fiber run and add a fiber to MODBUS 485 converter? What brand would you recommend?
Does anyone have any other suggestions?
