This message indicates that the same exception report value is being imported into a module twice.
Duplicate off-module reference (AI/I Reference) to Module 1,08,31 Block 25038 in module 10607: files 1060732B.CAD and 1060733B.CAD
Duplicate off-module reference (DI/I, DI/I) to Module 13,03,04 Block 1523: G5702F4 and G5702F7
You can find these in your M14 file by searching for the block then clicking on the exception report import blocks that are in the same module.
This is a serious problem if the import block is in use, because one of the values is always frozen. When you switch to the redundant module, as you do for a configuration change, the one that was working freezes and the other begins working.
In the case of analog blocks, the value will 'flat-line'. In the case of digital inputs, the imported value will simply fail to respond to a change in the source. This can be catastrophic.
Note also: Error messages can be built directly into your M14 file. For more information, see Building error reports into the M14.
