in a hybrid activity logic sheet. when a particular mode is not active does that mean that any logic blocks in the mode are not executed at all? i.e. a hybrid activity has states of off/on. if the state is off and there is a PID in the on section, does the PID effectively turn off or at least not execute? Just trying to understand how the controller executes blocks. TIA

Sounds more like you are looking at a state block, in which you are correct.

When I define a hybrid activity in custom logic, I make sure all input and output possibilities are defined.

thanks mackinaw, that's what I thought. Still getting used to the naming conventions in CCT...
