Week timer

Requirement
Requirement for a precise calculation is the time-of-day synchronization of the RTU.
Function
For the week time, three times (cams) can be specified per week using the function
parameters during which the output is set to 1.
If you select the "Pulse" option, at the turn on time only a single pulse with the length of an
update cycle is set at the output instead of being permanently ON. When the "Pulse" option
is selected, the behavior applies to all three cams.
The switching status of the week timer depends on the status of all three cams.
The three cams can overlap in time. If on and off times overlap, this will cause a conflict. In
this case, the earliest on and off times have priority. Example:
Table 5- 1

In this example the working time is 1:00 h to 1:40 h.
