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.
Prerequisites for this step:
- A PROFINET slave, created in TwinCAT.
Create a virtual slave as follows:
- 1. Right-click on the PROFINET device in the tree view on the left.
- 2. Click Add New Item.
- 3. Select the appropriate box, e.g. the CX2xx0 (Embedded PC) if you use a CX20xx Embedded PC with optional PROFINET interface.
- The virtual PROFINET slave is created in the tree view. You can now configure your own process data for the virtual slave.
The MAC address of the virtual slave is editable. Make sure that the MAC address occurs only once in the system. The IP address is assigned by the PROFINET master
