Chapter Five: Remote RS-232 Operation Setup Messages

The controller responds with the message [
S x value
], where:
x :
0 = Analog set point value
1 = Set point A value
2 = Set point B value
3 = Set point C value
4 = Set point D value
5 = Set point E value
value:
set points A to E: % of full scale (with pressure control)
% of open (with position control)
analog set point: % of the analog set point FS voltage range
To report the value for set point A, enter:
R 1
An example response, if set point A is set to 50% of full scale pressure, is:
S 1 50
To report the value for the analog set point, enter:
R 0
An example response, is:
S 0 100
Note
The request [R 0] reports the analog set point value as a percentage of
the analog set point full scale range voltage ; it does not report the
percentage of the controlling transducer’s range.
Refer to How To Calibrate the Full Scale of the Analog Set Point , for
more information.
