SYMPTOMS

Digital MOMO Match events are evaluated differently by the B3000 and B3000-B and may yield different Event/Reaction results. The B3000 reads the state of digital I/O when it starts to process event reactions (Event/Reactions are processed sequentially, Event/Reaction 001 is processed first, then 002, etc.), and uses those results to evaluate MOMO Match events. The B3000-B reads the state of digital I/O while processing each event, and uses those results to evaluate MOMO Match events.

For example, if there's a Reaction that changes the state of an output, it will be read by the B3000-B when it processes the next event. It will use the new state to evaluate any subsequent MOMO Match Events. This behavior may produce different results than if the original state (the B3000's behavior) were used to evaluate the MOMO Match.
