5.8. Detecting the first cycle with the M 255.15 variable
The bit M 255.15 should be used when the detection of the first cycle is required, for example,
to initialize certain parameters or set certain values to zero.
The description of how to use this bit is given in the following example.
The bit M 225.15 should be set to 1 before the end of the first cycle. This bit has the
particularity of being set to zero systematically, whatever the backup configuration, at the
central unit startup.
