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.
1. In the project tree, right-click the created PROFINET Device
2. Click Add New Item...
Creating a virtual slave 1:
3. Depending on the configuration, select the appropriate box, e.g. the CX2xx0 if you are using a CX20xx Embedded PC with PROFINET optional interface.
Creating a virtual slave 2:
The virtual PROFINET slave is created in the project tree.
4. You can now configure your own process data for the virtual slave.
Creating a virtual slave 3:

The last byte of the MAC address of the virtual slave can be edited. Make sure that the MAC address occurs only once in the system. The IP address is assigned by the PROFINET master.

Creating a virtual slave 4:
