xPC Target and ABB ModbusTCP

Hello,

We need to control an ABB ACS-800 drive with an RETA-01 Modbus/TCP module. This module also support EtherNet/IP communication. Which driver should we use? Model-Based Ethernet Communications Support? Any example of ModbusTCP communication under xPC?

Thank you,

Guillaume Tremblay

As far as I know, Modbus isn't s supported protocol under xPC. You can use UDP to communicate between xPC Target and the ABB controller, or even Real-Time UDP in R2011a, but Model-Based Ethernet is probably as close to TCP/IP that you are going to get. I believe this required a dedicated network card.

HTH,

Thank you Arnaud for the prompt answer,

I spoke with an ABB product specialist and he told me that the easiest way for this drive is with ModbusTCP, its clients don't use xPC for that reason (they use another platform having Modbus support). The other way around is using Ethernet (no UDP) but it seem much more coding.
