Parameter Declaration Data type Description
UNDO_PAR INPUT/ OUTPUT BOOL UNDO CHANGE OF CONTROLLER PARAMETERS
n Loads the controller parameters PFAC_SP, GAIN,
TI, TD, D_F, CONZ_ON and CON_ZONE from the
data structure PAR_SAVE (only in manual mode).
n Default: FALSE
SAVE_PAR INPUT/ OUTPUT BOOL SAVE CURRENT CONTROLLER PARAMETERS
n Saves the controller parameters PFAC_SP, GAIN,
TI, TD, D_F, CONZ_ON and CON_ZONE in the
data structure PAR_SAVE.
n Default: FALSE
LOAD_PID INPUT/ OUTPUT BOOL LOAD OPTIMIZED PI/PID PARAMETERS
n Loads the controller parameters GAIN, TI, TD
depending on PID_ON from the data structure
PI_CON or PID_CON (only in manual mode)
n Default: FALSE
PID_ON INPUT/ OUTPUT BOOL PID MODE ON
n At the PID_ON input, you can specify whether or
not the tuned controller will operate as a PI or PID
controller.
– PID controller: PID_ON = TRUE
– PI controller: PID_ON = FALSE
n It is nevertheless possible that with certain process
types, only a PI controller will be designed despite
PID_ON = TRUE.
n Default: TRUE
GAIN_P OUTPUT REAL PROZESS PROPORTIONAL GAIN
n Identified process gain. For the process type I,
GAIN_P tends to be estimated too low.
n Default: 0.0
TU OUTPUT REAL DELAY TIME [s]
n Identified delay of the process.
n Default: 0.0
n Range of Values: ³ 3*CYCLE
TA OUTPUT REAL RECOVERY TIME [s]
n Identified system time constant of the process. For
the process type I, TA tends to be estimated too
low.
n Default: 0.0
KIG OUTPUT REAL MAXIMAL ASCENT RATIO OF PV WITH 100 % LMN
CHANGE
n GAIN_P = 0.01 * KIG * TA
n Default: 0.0
N_PTN OUTPUT REAL PROCESS ORDER
n The parameter specifies the order of the process.
"Non-integer values" are also possible.
n Default: 0.0
n Range of Values: 1.01 to 10.0
