PLC-API Requirements 5.4.3 FB_CTRL_3POINT The function block provides a 3-point transfer element in the functional diagram. Behaviour of the output: VAR_INPUT VAR_INPUT fSetpointValue : FLOAT; fActualValue : FLOAT; nManSyncValue : INT; bSync : BOOL; eMode : E_CTRL_MODE; END_VAR fSetpointValue : Set value of the controlled variable. fActualValue : Actual value of the controlled variable. nManSyncValue : Input through which the 3-point element can be set to one of the three branches. nManSyncValue >= 1 → bPosOut = TRUE, bNegOut = FALSE nManSyncValue otherwise → bPosOut = FALSE, bNegOut = FALSE bSync : A rising edge at this input sets the 3-point element to the value fManSyncValue. eMode :
