SRCE Constants
The SRCE Constants are used to identify the state of the input or output.
| Constant Name | Syntax | |
|---|---|---|
| ALTERNATING | [SRCE.ALTERNATING] |
| HIGH | [SRCE.HIGH] |
| LATCH HIGH | [SRCE.LATCHHIGH] |
| LOW | [SRCE.LOW] |
SRCE Target Variables
The SRCE is able to set the outputs to either a continuous signal or a pulsed signal. The continuous signal will set any one of the outputs to the High state, either indefinitely or for a defined time frame. The pulsed signal will cause the output to alternate between High and Low every second, either indefinitely or for a defined time frame. The Low signal will turn the output signal off until it receives another signal.
| Variable Name | Syntax | |
|---|---|---|
| Digital Output Y1 High {} | [SRCE.Y1h] {duration} |
| Digital Output Y1 Low | [SRCE.Y1l] |
| Digital Output Y1 Pulse {} | [SRCE.Y1p] {duration} |
| Digital Output Y2 High {} | [SRCE.Y2h] {duration} |
| Digital Output Y2 Low | [SRCE.Y2l] |
| Digital Output Y2 Pulse {} | [SRCE.Y2p] {duration} |
| Digital Output Y3 High {} | [SRCE.Y3h] {duration} |
| Digital Output Y3 Low | [SRCE.Y3l] |
| Digital Output Y3 Pulse {} | [SRCE.Y3p] {duration} |
| Digital Output Y4 High {} | [SRCE.Y4h] {duration} |
| Digital Output Y4 Low | [SRCE.Y4l] |
| Digital Output Y4 Pulse {} | [SRCE.Y4p] {duration} |
The {duration} values above are optional. If included, the values will be in seconds. For example, to set output Y1 to High indefinitely, use the following target:
[SRCE.Y1h]
Or, to set output Y3 to Pulse for 60 seconds, use the following target:
[SRCE.Y3p{60}]
Extended SRCE Source Variables
The Extended SRCE adds two modules to the Standard SRCE. The first module contains eight digital inputs. These digital inputs have all the same functionality as the Standard SRCE digital inputs. There are two hardware modules available for the second module:
- Four 0-10 volt analog inputs
- Four 4-20 mA analog inputs
The following variables are available with the Extended SRCE only.
