DX581-S Process voltage is switched off (Siemens)
Dear Experts,
I've been trying to set the safety module dx581-S and I keep getting the following fault.

I've checked the 24VDC of the process voltage and everything is okay, I've checked the 0 common and also good, CRC is good, Safety address good...
Does anybody had this problem before? Is it an electrical problem or i'm missing some configuration?
Thank you in advance for your help,
Marc

Answers
Have you got 24v on the UP rail (1.8) and the ZP rail (1.9)? The module needs to be powered separately to the host coupler/CPU. Also check your power sequencing: If the module enters a fault state from power it will need a full reboot to clear, including the host coupler and UP rail.
