PLC-API Requirements 5.4 Controller 5.4.1 FB_CTRL_2POINT The function block provides a 2-point transfer element in the functional diagram. Behaviour of the output: VAR_INPUT VAR_INPUT fSetpointValue : FLOAT; fActualValue : FLOAT; bManSyncValue : BOOL; bSync : BOOL; eMode : E_CTRL_MODE; END_VAR fSetpointValue : Set value of the controlled variable. fActualValue : Actual value of the controlled variable. bManSyncValue : Input through which the 2-point element can be set to one of the two branches. bSync : A rising edge at this input sets the 2-point element to the value bManSyncValue. eMode : Input that specifies the block's operating mode [ } 16] .
