Supported communication protocols

The GESRTP Communication Driver communicates with clients and PLCs using different communication protocols. The Communication Driver uses application protocols such as OPC, DDE, SuiteLink, and PCS to communicate with the clients, and TCP bus protocols over the Ethernet to communicate with the PLCs.

For more information refer to the "Supported Client Protocols" section of the AVEVA Communication Drivers Pack Help.

The GESRTP Communication Driver can have a maximum of 75 outstanding OPC/DDE/SuiteLink/PCS transactions.

Device communication protocols

The GESRTP Communication Driver uses only the GE Service Request Transfer Protocol, which is a TCP bus communications protocol over Ethernet, to communicate with the GE family of controllers.
