Parameter Declaration Data type Description
TM_LAG_P OUTPUT REAL TIME LAG OF PTN MODEL [s]
n Time lag of PTN model (values only for N_PTN ³
2).
n Default: 0.0
T_P_INF OUTPUT REAL TIME TO POINT OF INFLECTION [s]
n Time from process excitation until the point of
inflection.
n Default: 0.0
P_INF OUTPUT REAL PV AT POINT OF INFLECTION - PV0
n Process variable change from process excitation
until the point of inflection.
n Default: 0.0
n Range of Values: Value range of the process value
LMN0 OUTPUT REAL MANIPULATED VAR. AT BEGIN OF TUNING
n Detected in phase 1 (mean value).
n Default: 0.0
n Range of Values: 0 ... 100 %
PV0 OUTPUT REAL PROCESS VALUE AT BEGIN OF TUNING
n Default: 0.0
n Range of Values: Value range of the process value
PVDT0 OUTPUT REAL RATE OF CHANGE OF PV AT BEGIN OF TUNING
[1/s]
n Sign adapted
n Default: 0.0
PVDT OUTPUT REAL CURRENT RATE OF CHANGE OF PV [1/s]
n Sign adapted
n Default: 0.0
PVDT_MAX OUTPUT REAL MAX. RATE OF CHANGE OF PV PER SECOND [1/s]
n Maximum rate of change of the process variable at
the point of inflection at the (sign adapted, always >
0), used to calculate TU and KIG.
n Default: 0.0
NOI_PVDT OUTPUT REAL RATIO OF NOISE IN PVDT_MAX IN %
n The higher the proportion of noise, less accurate
(less aggressive) the control parameters.
n Default: 0.0
NOISE_PV OUTPUT REAL ABSOLUTE NOISE IN PV
n Difference between maximum and minimum
process variable in phase 1.
n Default: 0.0
