System Manual, V2.3, 07/2017, A5E03822230-AF

The following figure depicts the flow of a typical scan including the Local memory usage and

two interrupt events, one during the program-execution phase and another during the

communications phase of the scan cycle. Subroutines are called by the next higher level,

and are executed when called. Interrupt routines are not called; they are a result of an

occurrence of the associated interrupt event.
