For the rung example below:
1) If instruction 1 is false, instructions 2, 3, 4, 5, 6, 7
take zero execution time.
Execution time = 4 + 18 = 22 microseconds.
2) If instruction 1 is true, 2 is true, and 6 is true, then
instructions 3, 4, 5, 7 take zero execution time.
Execution time = 4 + 4 + 4 + 18 = 30
microseconds.

This only includes the amount of time needed
to “set up” the operation requested. It does not
include the time it takes to service the actual
communications.

These instructions take zero execution time if
they are preceded by conditions that guarantee
the state of the rung. Rung logic is solved left
to right. Branches are solved top to bottom.
