Branching Combinations and Limitations
Use branching to avoid redundant instructions, speed-up processor evaluation, and
provide more efficient programming.
APS allows branching combinations to be programmed in the fixed, SLC 5/01, SLC
5/02, SLC 5/03, and SLC 5/04 processors, and the MicroLogix 1000 controllers.
(Note that the Hand-Held Terminal (HHT) does not allow nested input and output
branches to be programmed in a fixed or SLC 5/01 processor.)
Extended Branching Versus Nested Branching
Using extended branches rather than nested branches is more ef
ficient and speeds up
processor evaluation. Both of the examples shown below accomplish the same
result; however, the extended branching example is evaluated approximately 1 ms
faster than the nested branching example.
