What causes error 'The topological type is incompatible...' when performing a Build in Unity Pro?



Located variables must be of type EBOOL in Unity Pro. Defining located variables as BOOL will cause this error when building the project.
BOOL (BOOLEAN) and EBOOL (Extended BOOLEAN) datatypes each occupy one byte in memory.

BOOL types have two states, 0 (False) or 1 (True) .
EBOOL types have three states, 0 (False), 1 (True) and a History state. This third state requires a byte allocation in PLC memory for the EBOOL..
