Last edited by: fritz at: 9/16/2010 2:22 AMSecond attempt to get my answer into the body of this thread, it will hopefully work this time. Preview does NOT work, so I''''ll add my answer into the Edit Notes and hope it works: Hello Goodas Allow me to give you more than 2 possible reasons (theorectical or otherwise) for this to take place: 1.) Block Status monitoring shows the DQ as ON, but some other Block (called after the one that is monitored) resets the DQ (last call that manipulates the DQ in the cycle "wins"). 2.) + 24V is missing on the DQ card 3.) 0V is missing on the DQ card 4.) faulty DQ card 5.) DQ address does NOT exist (e.g. you think that DQ card in Rack X Slot Y should have start address xyz but in fact has start address abc). 6.) DQ card is last in rack and Backplane connector to it is missing (or broken) (and CPU is configured to start up even if actual and expected configuration differ). There''''s probably a few more theorectical reasons, but that''''s all from me for now. Last edited by: fritz at: 9/16/2010 2:06 AMCheers |
