Reading PID Constant and the Control Period
This section covers four commands: Proportional Band Read, Integral Time
Read, Derivative Time Read, and Control Period Read. The command and re-
sponse formats for these are nearly the same. The numeric values returned for
data do vary.
Note
The following commands can not used during autotuning.
Command Format
The formats for all of these commands require the unit number, control point,
and memory bank for which the read is intended.
