In the online help for this fct you'll find detailed description how toparametrize it. SSL-ID for LED status is W#16#19 for all possible LEDs or W#16#119 with appropriate index for just one LEDs status. Index for INTF is W#16#0002 and for EXTF it is W#16#0003. From visu then you read resulting tags.

But take care about data validity, the data are valid when #Busy is zero and I suppose to trigger the SFCcalling, because continuous calling can cause bigger load for CPU (it means longer execution time of user program cycle).
