Table 9- 23 Input paramters TCONT_S
CYCLE 0.0 REAL 0.1 s At this input, you enter the sampling time for the controller.
SP_INT 4.0 REAL 0.0 The input "Internal setpoint" is used to specify a setpoint.
The valid values depend on the sensors used.
PV_IN 8.0 REAL 0.0 At the "Process variable input" you can assign parameters
to a commissioning value or you can interconnect an ex-
ternal process value in floating-point format.
The valid values depend on the sensors used.
PV_PER 12.0 INT 0 The process value in I/O format is interconnected with the
controller at the "Process value I/O" input.
DISV 14.0 REAL 0.0 For feedforward control, the disturbance variable is inter-
connected to the "Disturbance variable" input.
LMNR_HS 18.0 BOOL FALSE The signal "Control valve at high endstop" is interconnect-
ed on the input "High endstop signal of position feedback".
• LMNR_HS=TRUE: The control valve is at high end-
stop.
LMNR_LS 18.1 BOOL FALSE The signal "Control valve at low endstop" is interconnect-
ed on the input "Low endstop signal of position feedback".
• LMNR_LS=TRUE:
The control valve is at low endstop.
LMNS_ON 18.2 BOOL TRUE
Manipulated value signal processing is switched to manual
mode at the "Enable manual mode of manipulated signal".
LMNUP 18.3 BOOL FALSE In manual mode of manipulated signals, the output pa-
rameter QLMNUP is operated at the input parameter "Ma-
LMNDN 18.4 BOOL FALSE In manual mode of the manipulated signals, the output
parameter QLMNDN is operated at the input parameter
"Manipulated signal down".
