communication between PP877 and AC800m PLC.
I am going to make communication between PP877 and AC800m PLC. As earlier I have worked on same PLC and PP835 with MMS communication and its more than easier. So is there MMS communication possible between PP877 & AC800M? if not so which one protocaol is suitable to work with same configuration? while I am using OPC server communication but here I am getting more difficulty to linking tags. So please tell me how to COMLI work? if you have any document please provide me.
