Creating variables
The EtherCAT slave has a simple structure and consists of inputs, outputs and InfoData. In TwinCAT you
can add process data to the inputs or outputs, which can later be linked to variables from the PLC program.
This section describes how to create such data.
Prerequisites for this step:
• A device with EtherCAT slave interface (B110) must already have been added as target system in
TwinCAT.
Create the process data as follows:
1. In the tree view, right-click on the inputs or outputs.
2. Click on
Add New Item
in the context menu.
The Insert Variable window appears.
3. Find the required variable type and click
OK
.
ð
You have successfully created process data. The new variable is shown in the tree view on the left. In
this way you can add further process data or variables for the EtherCAT slave.
