Ambiguous wiring [ERROR 121]

Ambiguous wiring [ERROR 121]

Ambiguous wiring at 1000,1200: multiple wires at sink Module 1,01,02 Block 1001 FC 1 input 0

Wiring has been found that cannot be resolved. The intent of the wiring is not clear and may be in error. DBDOC cannot make the correct connections.

When you see this, use Composer or WinCAD to look at the wiring to find what is confusing and fix it.

This message appears when DBDOC could not figure out the wiring and did not connect blocks to inputs where they are used. In the case below, we can guess that the line circled is really two separate line segments (quite possibly both digital dashed ones) and we could not figure out what to do, though it may be obvious to someone when he actually looks at it, of course.
