General Information

• The function block must be called in every cycle.
• It is possible to use different methods in a single cycle, as well as multiple calls to the same method in a cycle.
• The methods only apply to an internal buffer (no direct influence on the terminal with the connected hardware) (exception: DirectCommands). To display the changes, a rising edge must be applied to the bShow input of the function block.
• You must wait as long as bBusy is TRUE.

Linking the function block

The function block provides variables that can be linked to the terminal via the "PLC" tab in the System Manager. The following adjustments must be made in preparation:

1. Configuring the slots depending on the connected hardware

2. Activating all process data

3. Creating the "PLC" data type per channel and linking the function block
