Once True Always True Block

Operations

When the True/False statement turns TRUE, will become fixed as TRUE for the life of the algorithm.

ADL Tip: may turn TRUE and then back to FALSE while a single discrete event message is being propagated - this will not set to TRUE; Once True Always True Block will only consider the final value of determined at the end of the propagation. This tip describes the block's operation at a microsecond granularity level.
