Getting the ACT LED status

Dear all,

Currently i am working with S7-412-5H & IM153-2(6ES7 153-2BA02-0XB0) with IO modules - 2 No's.

I have to show the led status of all IM modules in HMI. 

With SFC 13, I tried but i am not able to find the exact byte address for run,SF, BF, active led status.

I checked the Manual "ET200M operating instructions but still not.

Please help me to find out the exact address for the same.

Regards,

San

You can use SFC51 for this.

1) For SF set SSL-ID = W#16#0692

Please check this FAQ. 

"The status of the DP slave with Address 1 is in Bit 0 of the first byte. If this bit is set, then that DP slave is either defective or disabled. "

2) For BF set SSL-ID = W#16#0292

Please not that these value are valid only if you are using integrated CPU interface. For external DP interface values are  W#16#4692 and  W#16#4292.

For more information you can check the help for sfc51 in your Step 7 installation.
