I have recent two PLC one GE 90-30 and second ABB ac800m. there is communication on base of profibus. I want to change to Ethernet based. is it possible? what needs to be updated? I want to have only Ethernet communication in the plant.

 

do you want to exchange data between ABB and GE PLC? try using MMS. you can use Ethernet as physical media and get the data you want using PPP. what way are you planning to use it? how is it with Profibus? using a DP-DP coupler?

 

MMS is an ABB messaging system. It wont be supported by GE.

TCP/IP comms between these vendors is probably limited to either Modbus TCP or OPC over ethernet. Using OPC will require another intermediate computer so realistically you're looking at Modbus TCP.

OPC is the best solution in my opinion here. It's easier and much quicker to implement. You will need an OPC Server for GE Fanuc:

and an OPC Data Manager:

ABB AC800 should come with its own OPC ... so all you need to do is connect that to Data Manager and connect the GE OPC server to Data Manager and volia you bridged them together

Let me know if you have any questions.
