I'm about to connect an old PLC to a control system and wonder if there is a Modbus protocol in the OMRON C200HE PLC. At first look I can't find any. I have a RS232C port avaible, but wonder if it's possible to set it up as Modbus.
We make a protocol converter that will convert Omron Host Link protocol to Modbus. Have a look at our Omnii-Comm product http://www.miille.com/din266-p00.pdf for more information. There is no PLC programming required.
