Creating a virtual slave

Additional virtual slaves can be created on the same hardware interface. This enables more data to be exchanged with a PROFINET master, or a connection with a second PROFINET master can be established.

Each virtual slave is assigned a dedicated address via TwinCAT and is configured like an independent device for the PROFINET master.

A PROFINET Device is available in TwinCAT.
