rfbcSetSwitchState (Function)

This function will send a switch-change request.

Most devices will only accept switch-change requests when paired with the RTCU device.

Note: if the request is broadcasted then the function will not wait for any confirmation.

Input:

id  : DINT [0 .. 16_777_215] (default 0)

The ID of the device to receive the request.

If the ID is "0" (zero), the request will be broadcast.

output : SINT [0..31] (default 1)

The index of the output to update.

state : BOOL (default ON)

Output:

None.

Returns: INT

Declaration:

FUNCTION rfbcSetSwitchState : INT;
VAR_INPUT
  id          : DINT := 0;
  output      : SINT := 1;
  State       : BOOL := ON;
END_VAR;

Example:

INCLUDE rtcu.inc
 
VAR_INPUT
  hisId : DINT;
END_VAR;
 
PROGRAM example;
hisId := 208024011 MOD 16#FFFFFF; // id of known device
rfbcOpen();
BEGIN
 ...
  rfbcSetSwitchState(id := hisId, output := 1, state := ON);
 ...
