Table 13: Pid Tuning Parameters - Honeywell ST700 User Manual

The values given for these tuning parameters are valid under the following conditions:
•
The values assume that the minimum configurable PID function block execution period
(T ) is 0.125 seconds.
s
•
Algorithm typesetting (A, B, or C) has no effect on the validation of these tuning
parameters.
The PID function block rejects all values outside the following ranges:
Parameter Initial
Value
PV_FTIME 0
GAIN 0
GAIN_NLIN 0
RATE 0
(sec.)
RESET +INF
(sec.)
OUT_LAG
Ideal PID N/A
Robust PID 0
BAL_TIME 0

Comment
Units: seconds.
The value of ZERO is permitted to turn
off rate action.
The value of +INF is permitted to turn
off reset action. (Some versions of NI
configurator program cannot set +/-
INF).
Fixed for Ideal PID form - not
configurable.
Zero permitted which implies no output
lag.
Not used in Honeywell Implementation.
