Thread Starter

Is there a need in the market place for an industrial Ethernet TCP/IP
Network with the MODBUS Protocol encapsulated ?

Yes there is a need. But, I believe this is a standard product for many of the smaller I/O manufacturers and is quasi standardized with a
compliance lab at the University of Michigan. Opto22, Grayhill, Sixnet and others sell I/O that works with it. Do we need another standard for Modbus over TCP/IP. IMHO No.
