---|---|
0 | AOUT#.VALUE is driven by AOUT#.VALUEU. |
1 | AOUT#.VALUE is driven by an action in the Action table |
2 | AOUT#.VALUE is driven by the associated fieldbus object |
3 | AOUT#.VALUE is driven by an event in the Sequencer |
Examples
Usage
When AOUT#.SOURCE = 0 (User), then AOUT #.VALUE will be controlled by AOUT #.VALUEU.
When AOUT#.SOURCE = 1 (Action table), then AOUT #.VALUE will be controlled by the assigned action, if any.
When AOUT#.SOURCE = 2 (FieldbusA Fieldbus is an industrial network system for real-time distributed control (e.g. CAN or Profibus). It is a way of connecting instruments in a plant design), then AOUT#.VALUE will be controlled by the associated fieldbus analog output object 3800h sub 2.
When AOUT#.SOURCE = 3 (Sequencer), then AOUT#.VALUE will be controlled by the assigned event in the Sequencer.
Code
Changing output value with VALUEU and then changing SOURCE to be action table with no action configured:
--> AOUT1.SOURCE 0 (User) --> AOUT1.VALUE 0.000 V --> AOUT1.VALUEU 1 --> AOUT1.VALUE 1.000 V --> AOUT1.SOURCE 1 --> AOUT1.VALUE 0.000 V
