Table 14: Pid Tuning Parameters - Honeywell SLG 700 Option Manual

3.10.2.
Table 15 lists the valid ranges for the tuning parameters for the PID block. Note that OUT_LAG
parameter is not configurable when Ideal PID is selected (PID_FORM = 1) and can be configured
when Robust PID is selected (PID_FORM = 2).
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.

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.
