PLC-API Step response: ARW: VAR_INPUT VAR_INPUT fSetpointValue : FLOAT; fActualValue : FLOAT; fManSyncValue : FLOAT; bSync : BOOL; eMode : E_CTRL_MODE; bHold : BOOL; END_VAR fSetpointValue : Setpoint of the controlled variable. fActualValue : Actual value of the controlled variable. fManSyncValue : Input with which the PID element can be set. bSync : A rising edge at this input sets the PID element to the value fManSyncValue. eMode : Input that specifies the operation mode [ } 16] of the function block. bHold : A TRUE at this input will hold the internal state (and therefore also the output) constant at its current value, independently of the control deviation.
