Time Circulation algorithm (together with redundancy function)

This algorithm is used in systems where it is necessary to alternate the operation of mechanisms (pumps, fans, air conditioners) over time, or on the run hour meters. For example, a set of 2 units is used, which must be alternated in time. If an error occurs on some unit, then the algorithm starts working only on the working (redundancy function). An example of setting the required registers is given below:

For simplicity and clarity, it is better to split the scripts into functional modules that can be quickly analyzed and placed in the right order in the program list. The first script looks at the errors and if they do not exist, the air conditioners alternate in time.

CIRCULATION_TIME = 30; -- for tests circulation time is short
