Maybe someone else has had a similar problem.And a possible resolution.

rack1-----"""""""""----rack2-----rack3
Communications is blue hose. The problem is that there is two It8 modules in rack 2 and 1 It8 module in rack3. The module that resides in rack three gives consistant readings with the actual thermocouple readings. The modules in rack two has channels that read up to 20% high at times. But here's where I'm getting lost. If i switch modules around between all three slots the problem always resides with the modules in rack2, but the channels the problem is on changes with the modules.But when any module is in rack3 it reads consistant and accurate.
Now a little history. When the machine was new rack2 would fault every couple days. There was some disagreement as the actual problem but whenever I would dissassemble that rack and reseat all the "backplane" plugs the system would be fine for a considerable time. Dayshift was trying to tell me that the blue hose was bad(they replaced it only to get more faults on rack2) but rack 3 also used this section of it and it never had a fault. The last time I got the fault I went over every pin on the backplane connectors to ensure a reliable connection. But i'm not sure if dayshift have done anything else.
The panel that rack2 is on has a fair amount of vibration and considerable heat fluctuations(over time). Where rack3 is the temp is relativly consistant and minimal vibration. all areas are in an area with "airborne oil" (part of the process is spraying oil on a machined wheel to produce a product)
I finally talked my "superiors" to get me a new module (I wanted 2 but......)Now that its installed in rack2 I still have the same problem (and feel like a shmuck).
Starting to wonder if i'm going nuts...
Then again I think we are all nuts just some of us have been caught!!!
But i'm feeling much better now!!!!!!
Thanks
