Discrete I/O for Communications

Discrete I/O augments the communications of the RMC. Discrete I/O is typically faster and more deterministic than the communications, and is therefore well-suited for starting a sequence in one or more RMCs at a specific time.

Some example uses of discrete I/O for communications:

Start or Stop User Programs
Use the Program Triggers to start and stop User Programs based on an input.
Affect flow of User Programs
Use inputs in the Conditional Jump link type to make link conditions that affect the flow of the User Programs.
General input and output
Turn outputs on and off from within User Programs and use inputs in Expressions.
