navUserIDReceiveX (Functionblock)

navUserIDReceiveX is an extended version of navUserIDReceive and returns the information of the user ID change.

Note that the user ID is only valid after a "User ID" event is raised; the event will be removed when this function block is called.

A "User ID" event is raised when the user ID is changed in the navigation device or is requested with navUserIDRequest.

If the status indicates that the user ID requires authentication, then the navUserIDAuthenticate function must be called.

Failure to do this will result in the "User ID" event being raised in regular intervals by the navigation device.

Input:

None.

Output:

time : DINT

The timestamp when the specified user ID took effect.

index : SINT

The index of the user.

user : STRING

The ID of the user.

If no user ID has been set, the string will be empty.

password : STRING

The password of the user.

status : SINT

Declaration:

FUNCTION_BLOCK navUserIDReceiveX;
VAR_OUTPUT
  time     : DINT;
  index   : SINT;
  user     : STRING;
  password : STRING;
  status   : BOOL;
END_VAR;

Example:

INCLUDE rtcu.inc
 
VAR
  userID : navUserIDReceiveX;
END_VAR;
 
FUNCTION ReadUserID;
  userID();

    DebugMsg(message := "*** user ID received ***");
    DebugFmt(message := "-time=\4", v4 := userID.time);
    DebugFmt(message := "-idx= \1", v1 := userID.index);
    DebugMsg(message := "-user=" + userID.user);
    DebugMsg(message := "-pass=" + userID.password);
  END_IF;
  IF userID.status = 2 THEN
    navUserIDAuthenticate(accept := TRUE);
  END_IF;
END_FUNCTION;
