I have a problem with an analog output sm332, it says "I / O access error or parameter assignment error" the error came after I moved modules from the Rack 0 to Rack 1, IM365 sitting in slot 3, and SM332 sitting beside in slot 4
under the tap "Diagnostis interrupt" is there a messeage: Parameters have not been assigned to the module.
they are all 0-10v (E)
I changed PQW 363-374 to 384-391 in the program, but the error is still there, does anyone know what to doo.

Hej Allan.

It is not clear to me what you have done. You write you moved modules IM365 and SM322 from rack 0 to rack 1.
The two IM365 modules makes the connection between the racks, so I guess that IM365 was not moved, or what ?
Did the SM322 card sit in slot 11 in rack 0 ?
Post a screenshot of the HW configuration before the change.

Try to go back to the previous situation before you added the CP343-1 LEAN card.
Remove the CP343-1 LEAN and move the SM322 back to rack 0, and load the old program. If the problem does not clear it seems that the SM322 is defective.
 
sm332 analog output moved from rack 0 slot 11 to rack 1 slot4, im365 did not move
cp343-2 was inserted in rack 1 slot 11
 
Maybe this can help:

All it says is that the CPU cannot access the address PIW384 of the analog card.

Try what I suggested before:
Try to go back to the previous situation before you added the CP343-1 LEAN card.
Remove the CP343-1 LEAN and move the SM322 back to rack 0, and load the old program.
 
Can you post your project here? Would be easier to check out that way..
