Can we connect AC800M CPU with TCP/IP?
I saw AC800F can send and receive data through TCP server.
We want do the same thing with ac800M cpu.
Because our HMI is under linux, and all the software is under linux too. it is hard to run OPC server and client. We want to communicate with the cpu through ethernet.
Is there any libs we can use in CM 800M to realize this function?
looking forward of your reply.
I am not aexpert with AC 800M, But having information that as far as you access controller by IP you can communicate. following library is available “The CI873 EtherNet/IP-DeviceNet hardware Library, CI873EthernetIPHWLib”. Not sure it is possible to communicate with linux based HMI.
Hope it helps to you...
Is your unix-based SCADA or DCS supports VIP messages? If so, you can try CI861 (TCP/IP VIP) and rmcEthernetLib library for the message exchange.
No other way I see for this issue: AC 800M using MMS over TCP/IP for communication, AC 800M OPC server running over that MMS-server and no MMS server for unix-based systems exist at the moment.
