PLC-API tCtrlCycleTime : Cycle time with which the control loop is processed. This must be greater than or equal to the TaskCycleTime. The function block uses this input value to calculate internally whether the state and the output values have to be updated in the current cycle. tTaskCycleTime : Cycle time with which the function block is called. If the function block is called in every cycle this corresponds to the task cycle time of the calling task. Area eCTRL_PARAMETER_RECORD_ HEATING : fKp_heating : Controller amplification / controller coefficient tTn_heating : Integral action time. The I-component is deactivated if this is parameterized as T#0s. tTv_heating : Derivative action time.
The D-component is deactivated if this is parameterized as T#0s. tTd_heating : Damping time Area eCTRL_PARAMETER_RECORD_ COOLING : fKp_cooling : Controller amplification / controller coefficient tTn_cooling : Integral action time. The I-component is deactivated if this is parameterized as T#0s. tTv_cooling : Derivative action time. The D-component is deactivated if this is parameterized as T#0s. tTd_cooling : Damping time nParameterChangeCycleTicks The number of task cycles over which the change from one parameter set to the other takes place. fOutMaxLimit : Upper limit at which integration is halted and to which the output is limited (ARW measure).
Reaching this limit is indicated by a TRUE at the bARWActive output. fOutMinLimit : Lower limit at which integration is halted and to which the output is limited (ARW measure). Reaching this limit is indicated by a TRUE at the bARWActive output. bPInTheFeedbackPath : Input value of the P element can be selected with this input (see functional diagram). bDInTheFeedbackPath : Input value of the D element can be selected with this input (see functional diagram). bARWOnIPartOnly : If this parameter is FALSE (the default setting), the integration of the I-component is halted if the complete controller output reaches the upper or lower limit.
If it is TRUE, the integration is halted if the I-component (the output of the integrator) reaches some limit.
