DIO#.SOURCE
Description
DIO#.SOURCE sets the digital output source when the digital I/O pin is configured as an output through DIO#.DIR.
| Value | Description |
|---|---|
| 0 - User | User controls the output value using DIO#.STATEU |
| 1 - Action Table | Action table controls the output value |
| 2 - Fieldbus | Fieldbus controls the output value |
| 4 - Compare | Compare channel controls the output value |
| 5 - MechaWare | MechaWare model controls the output value |
| 6 - PWM Generator | PWM generator controls the output value |
Examples
Usage
0: User controlled. DIO#.STATE is set by DIO#.STATEU.
1: Action table controlled. DIO#.STATE is set by the assigned action, if any.
2: Fieldbus controlled. DIO#.STATE is set by the fieldbus output control 3681h Digital output control sub 1.
4: Compare channel controlled. DIO#.STATE is set by the compare channel output. The specific channel is selected by DIO#.SOURCEID
5: MechaWare controlled: DIO#STATE is set by a MechaWare model.
6: PWM generator controlled: DIO# is used to output a PWM signal configured by PWM#.DUTYCYCLE and PWM#.PERIOD. If multiple PWM generators are available, DIO#.SOURCEID selects the PWM generator to be used.
Code
Changing output state with STATEU and then changing SOURCE to be action table with no action configured:
--> DIO1.DIR 1
--> DIO1.SOURCE 0
--> DIO1.STATE 0
--> DIO1.STATEU 1
--> DIO1.STATE 1
--> DIO2.DIR 1
--> DIO2.SOURCE 1
--> DIO2.STATE 0
