15.5.4 FB 58 - TCONT_CP - Continuous Temperature Control
FB 58 TCONT_CP is used to control temperature processes with continuous or pulsed
control signals. You can set parameters to enable or disable subfunctions of the PID con-
troller and adapt it to the process.
Parameters
Parameter Declaration Data Type Description
PV_IN INPUT REAL PROCESS VARIABLE IN
n An initialization value can be set at the PV_IN input
or an external process variable in floating-point
format can be connected.
n Default: 0.0
n Dependent on the sensors used
PV_PER INPUT WORD PROCESS VARIABLE PERIPHERY
n The process variable in the peripheral I/O format is
connected to the controller at the PV_PER input.
n Default: 0
DISV INPUT REAL DISTURBANCE VARIABLE
n For feed forward control, the disturbance variable is
connected to the DISV input.
n Default: 0.0
INT_HPOS INPUT BOOL INTEGRAL ACTION HOLD IN POSITIVE DIRECTION
n The output of the integral action can be blocked in
a positive direction. To achieve this, the INT_HPOS
input must be set to TRUE. In a cascade control,
the INT_HPOS of the primary controller is intercon-
nected to QLMN_HLM of the secondary controller.
n Default: FALSE
