Hi,
I am trying to have several Modicon 948 PLCs on a S975 ModBus II comm processor network communicate with a Quantum PLC. I know that the S975 is very old technology but due to the fact that its the only cable that runs throughout my facility I have no choice. Is there an adapter that can convert the ModBus II to ModBus or ModBus+? The SA75 ModBus II interface module which is a PC AT card in not a good option.
Any ideas?
Thanks
A Jones
