Configuration of PLC Task and Synchronisation Mode

In Automation_Builder the PLC program is written and assigned to a PLC task. For task creation and parameterization the dialog “task configuration” is used.

The task configuration is evaluated when a PLC project is loaded and the corresponding sync mode is activated for the ETHERCAT master. The synchronization will be activated if the parameter task type is set to the value “triggered by external event”. The mode of synchronization can be selected with the parameter event. Between the value of the parameter event and the synchronization mode exists the following relationship:

Parameter	Value	Description
Event	Ext_CouplerX_InputAny	Sync mode 1
	Ext_CouplerX_Input2Any	Sync mode 2
	Ext_CouplerX_InputAny_high_prio	Sync mode 1 with increased priority
	Ext_CouplerX_Input2Any_high_prio	Sync mode 2 with increased priority
