End Codes If an end code of 00 was returned in the response, the command was executed
normally. If the end code is not 00, the desired data will not have been written.
Refer to
Section 4-1-2 End Codes for a description of the other possible end
codes and their meanings.
4-2-5 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.
