UPDATE: The The QW s are not being transferred to PQW and also PIWs are not transferred to IW. No fault on CPU, no message etc for the cards. It is in Run Mode, DI & DO cards do change status. When I added a transfer from QW to PQW, cards give +/- 10V O/P!! Hardware in question :Remote ET200S on profinet talking with IM11-8F PN/DP CPU. Card placement IM 6ES7-151, Power supply 6ES7-138, AO cards 6ES7-135 (x2), AI cards 6ES7-134 (x2), DO cards 6ES7-132 (x2), DI cards 6ES7-131 (x1) Hi, In one of the tool, the AO channels are set for +/- 10V. In Simatic Manager, online, the QW for the o/p shows changing value but the on the card it contantly shows 0 VDC, no changes. When all terminals are open it shows 15.5VDC, with 1,2 shorted and 3,4 shorted as per manual, it shows 0V (with or without load). Checked wiring as per manual, no card faults available online. The AO card doesn't have much to offer on diagnostic. Any idea? Edited 8 May 2012 by Ben
