[snip] However, I tried measuring a slot with a multi-meter. I expected when the slot was active, that I would see a spike in voltage, but I did not. I measured with the positive probe in the slot and the negative probe at ground. Shouldn't I see 24 V whenever the slot is active? ------------------------------------------------------------------------------------------ |

Have you compared your wiring to the reference drawing for that module? https://support.industry.siemens.com/cs/mdm/83501523 then open the wiring -> wiring & block diagram section. Note it has 2L+, 3L+, 1M, 2M, 3M
