Upgraded Mosaic from version 2019.1 to 2020.1 SP3 and now got error while compile program with one relational function block (see example on picture)

Compiler used in Mosaic 2020.1 SP3 has too strict type control. We are working on a fix that will allow to compare BOOL variables again.
Till the fix will be available, you can use workaround utilising function XOR

instead of NE, XOR can be used / instead of EQ, XOR with negated output can be used

Thanks, already used that solution, works like a charm.

Also will be waiting for fixed Mosaic update.

This question is solved.
