Reset (FB)

FUNCTION_BLOCK Reset EXTENDS BaseService

This function block is used for calling the reset service of a specific instance of a CIP object. The exact effect of this service depends on the CIP object (refer to the CIP specifications (Vol. 1 and 2). This instance call resets the DEVICE_123_ETHERNET device as soon as xExecute yields TRUE:

PROGRAM PLC_PRG
VAR
    reset : ENIP.Reset ;
END_VAR

reset(
    xExecute:= ,
    itfEtherNetIPDevice:= DEVICE_123_ETHERNET,  (* instance of the device (instance is found in the I/O Mapping of the device) *)
    eClass:= ENIP.CIPClass.IdentityObject,      (* cip class which contains the desired attribute *)
    dwInstance:= 1,                             (* value of 0 is class level, range from 1..x is instance level *)
    xDone=> ,
    xBusy=> ,
    xError=> ,
    eError=> );
    ;

Scope Name Type Comment Inherited from Input xExecute BOOL Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (xDone, xError) are present at the outputs for exactly one cycle.
