How can I use redundant EtherCAT masters on Simulink Real-Time?

Beckhoff's TwinCat allows configuration of redundant EtherCAT masters. This is fairly simple in the TwinCat software, and in fact it detects it automatically when scanning. I would like to use this feature, but I don't know how to implement that in Simulink Real-time. Can Simulink Real-time handle this sort of configuration? If so, how do I set it up?
