What happens?
When an action call is inserted, it has an input and output interface (call parameters) and an instance name.
If an instance name is declared for the action, then the error message appears when compiling the PLC project:
Unknown type: [Name der Aktion]
If the input interface of the action call is wired, this overwrites the input interface of the module to which the action is connected.
When does the behaviour occur?
The behaviour described above occurs when an action is called in an action of a function block in the FBD editor.
Which products are affected?
PLC Designer from V3.24
Short-term measures:
Delete all inputs and outputs of the call to action (context menu of the call to action: Remove unused FB call parameters).
Do not enter an instance name for this call to action.
Evaluation / recommendations:
In the Lenze Application Template, each machine module has an action that was created with the FBD editor. This function restriction can occur in this action.
