• Inconsistent LPM data [ERROR 10020]

The error types in this file that have not yet been converted are documented here:

--Parsing file E:\EBY45EB.CLD...
No legal LPM match found for IREF X09TT0527 on output 2

These messages cover situations where IREF text exists on an off-module input, but the reference text is already used as a local OREF reference.

This can arise in a conversion from WinCAD when the text on a local reference is the same as that needed on a global OREF required by an import block. Before Composer, the text on the import function code was not looked at.

The use of the same reference text in both a local reference and a global one is not valid. It would not be allowed in Composer, but can be imported. There may be no problem with the logic, but it is not robust. Either local or global reference should be made unique. As it is, there is no robust connection by way of Composer, because the text cannot be resolved.

In the example, it is possible that the real problem is that the DI/B import block, which is restricted to Loop 2 PCU 30, should actually be replaced with a DI/L block that can import by exception report from Module 2,20,04 Block 6839. Examination of the logic is required to find out how to resolve the problem.
