To report the type of control for setpoint A, enter:
R 26
If setpoint A is configured for pressure control, an example response is:
T 1 1
Setting the Analog Setpoint Range
The [A value] command sets the full scale voltage range for the analog setpoint, where:
value: 0 = -5 to +5 Volts (initial)
1 = -10 to +10 Volts
To query the voltage range of the analog setpoint, issue the request:
R 24
The controller responds with the message [A range], where:
value: 0 = -5 to 5 Volts
1 = -10 to +10 Volts
If the analog setpoint has a full scale range of 5 Volts, an example response is:
A 0
To change the full scale range of the analog setpoint to 10 Volts, enter:
A 1
Note
You can operate the device at a different full scale input, for example 4.5 V, by recalibrating
the full scale of the analog setpoint. Refer to Calibrating the A/D Converter, page 41, for
more information.
Setting the Setpoint Values
The [S x value] command sets the values for the setpoints, where:
x: 1 = Setpoint A value
2 = Setpoint B value
3 = Setpoint C value
4 = Setpoint D value
5 = Setpoint E value
6 = Analog setpoint value
value: setpoints A to E: % of full scale (typical values are between 0% and 100% of the sensor range
with pressure control)
% of open (0 to 100% with position control)
analog setpoint: 0 = 0 to 100% of the controlling transducer’s range
(normal resolution - initial)
1 = 0 to 10% of the controlling transducer’s range (10x normal resolution)
To set the value of setpoint A to 50% of full scale pressure, enter:
S 1 50
To report the value of a setpoint, issue the request:
R x
