SysEthernetLEDBlink (FUN)

FUNCTION SysEthernetLEDBlink : SysTypes.RTS_IEC_RESULT

Triggering the mechanism to blink a LED of an adapter specified by the MAC address for the specified duration. The operating system and hardware must support this feature. The function call doesn’t wait the given duration and returns as fast as possible. However the real-time capability of this call is not guranteed.
