Power problem with DQ module

Hi,

We are using CPU 1510SP-1 PN on PN network with 4XDI (131-6BF01-0BA0) and 4xDO (132-6BF01-0BA0) and 1xAI (134-6JD00-0CA1).

Screen shoot of our potencial power group is here.

Digital card on slot 8 doesnt have power on it,but the module next to him on slot 9 have power.

We done:

Check the voltige on red and blue input

Replace the module base with new one. 193-6BP00-0DA1

Replace the input voltage wires from another card power input that works.

Replace the module on base. 132-6BF01-0BA0

We have anothother  simular configuration also on PN that works.

I removed power from slot 10.,and card on slot 9 stil have power.So obviasly card on slot 9 takes power from slot 8 card that doens have power.

Thx , problem solved.

Someone swap base unit on AI and DQ on rack.

Thx for fast replay.
