Allen-Bradley PLC Battery Low Signal

[TRUNG PHI 0]

I want to receive a warning signal for PLC Battery Low.

With SLC 5/03 and software RSLogix500, I used bit S:5/11 ( Battery Low ) to indicate that warning in HMI.

Please let me know how I can do with CompactLogix 1769-L32E and software Studio 5000 Logix Designer.

This is an older post, but if you're still working on this, you could try a GSV instruction with:
Class Name = FaultLog

Attribute Name = MinorFaultBits

Dest = <some DINT tag you designate>

According to the instruction help, bit 10 should then tell you if there is currently a battery fault.  To get to this help page, put a GSV instruction on a rung somewhere, select it, and press "F1".  Scroll down into the description and find the link to "GSV/SSV Objects".  From there, click on "FAULTLOG"
