Adapt block: Adapted block does not exist [ERROR 021]

Adapt block Module 1,01,02 Block 1001 on drawing 1010200A.CAD:  Adapted block 1002 does not exist

This message means that an adapt block is attempting to adapt a block that does not exist.

On-site testing has confirmed that an adapt block continues to adapt its target block / spec, even if it has no input. Since block types cannot be changed, the unintentionally adapted spec is legal, but not likely correct.

As far as we have determined, if you try a cold reload of a block with these specs, the module will not run. You can, however, load the redundant controller and fail over to it with no problem. The error should be fixed to avoid giving you problems when you do not expect them.

Error 21 b.png

In the above image, the adapt block has an S2 value of 1383, however there is no block 1383 on the same module. This means that no adaptation is available. In the below image, spec 2 is a 0, so there is no block for this adapt block to adapt. Therefore this block is doing nothing.
