Synchronous call for the functions _activateDpSlave and _deactivateDpSlave

The synchronous call is recommended for MotionTasks.
With a synchronous call, the user program waits until the system function has been completed.
The return value directly indicates whether the function call was successful.
Proceed as follows for the synchronous call:
64
IF ( 0 <> bgrRequestActivate ) THEN
retVal := _activateDpSlave (
logicalAddressOfDpStation := bgrLogAddrDpSlave,
reqActDeactGetStateMode := bgrReqActDeactMode,
dpAlarmMode := bgrDpAlarmMode,
nextCommand := bgrNextCommand,
timeToWaitForStationAlarm := bgrTimeToWait
(* As of SIMOTION Kernel version V4.4
Waiting time for station ramp-up *)
);
CASE retVal OF
16#0000_0001: bgrRequestActivate := 0;
// Node successfully activated.
16#0000_0005: bgrRequestActivate := 0;
// Node was already activated, no alarm.
16#0000_7001: bgrReqActDeactMode := REQUEST_FALSE;
// Function started successfully
16#0000_7002: ; // Function running.
ELSE // Troubleshooting
bgrRequestActivate := 0;
END_CASE;
IF ( 0 = bgrRequestActivate ) THEN
// Function completed, prepare next call.
bgrReqActDeactMode := REQUEST_TRUE;
bgrResultActivate := retVal;
