TC3 Temperature Controller
Value range Description
INT Controller operating mode (1 = heating, 2 = cooling, 3 =
heating & cooling) (see below)
INT Parameterisable reaction to errors (see below)
LREAL Control value during the self-tuning (normally 100%)
LREAL Control value during the settling phase (normally 0%)
DWORD Masks out the alarms (see below)
TIME Controller's sampling time. In the course of the sampling
time the controller re-calculates the control value.
TIME Task cycle time. The FB is called with this time interval.
LREAL Minimum set value.
LREAL Maximum set value.
LREAL Rate of rise (of ramp).
LREAL Rate of fall (of ramp).
LREAL Set value at start-up.
TIME Time with the fWStartUp set value.
[TRUE,FALSE] Switches on ramping during the start-up phase.
LREAL Rate of rise (of ramp) during the start-up phase.
LREAL Rate of fall (of ramp) during the start-up phase.
LREAL Minimum value of the control variable.
LREAL Maximum value of the control variable.
LREAL Control value in manual operation.
LREAL Control value in case of error (parameterisable).
TIME Cycle time of the PWM signal.
TIME Time constant of the actual value filter (first order P-T1
filter)
[TRUE,FALSE] The actual value filter is actuated if TRUE.
[TRUE,FALSE] Switches pre-controller on.
[TRUE,FALSE] Switches open loop characteristic on until close to set
value.
[TRUE,FALSE] Switches on control value filter following the main
controller.
ENUM Selection of a filter type for the control value filter
following the main controller (see below)
ENUM Selection of a control algorithm (see below)
LREAL Relative lower temperature limit in the first band.
LREAL Relative lower temperature limit in the second band.
LREAL Relative upper temperature limit in the first band.
LREAL Relative upper temperature limit in the second band.
LREAL Absolute upper temperature limit.
LREAL Absolute lower temperature limit.
