Hi, I am having a CPU 1215FC DC/DC/DC (6ES7 215-1AF40-0XB0) V4.1 connected to the SM 1223 DI8/DQ8 x 24VDC (6ES7 223-1BH32-0XB0) V2.0. If i remove the supply (24VDC: both L+ & M) to the module, there is no changes on the diagnostic LED on the module & the CPU as well. Can anyone advise on why there is not indication of the "power supply removed"? The Diagnostic LED on both the module & CPU is steady green. There is also no indication on the diagnostic buffer (online & diagnostics) via TIA Portal. Is there any way to enable the diagnostics for the power supply removal for the module? ------------------------------------------------------------------------------------------ |

Look at the hardware configuration properties of the module. If it has a checkbox for the L+ power supply for diagnostics, you may have that setting disabled. Not all modules have all diagnostics options. If it is important, you have a couple options. 1. Get a higher-end module with the L+ power diagnostics option (if your module does not have it) 2. Wire up L+ to a spare DI.
