Summary
It may be desired that events can be specified by a time program and that these should be corrected automatically, depending on other influencing variables.
An example: A shift supervisor should be able to enter the working hours for his shift in a time program. Depending on the difference between the desired temperature in the hall and the actual temperature, the lead time for the heating should be determined and another time program for the correct heating times should be automatically created.
Details
This is a relatively complex solution. When loading the time programs, the global script of the process server checks whether additional time programs should be created for them that contain the real switching times. In the preparation of these time programs,
- Lead times
- Follow-up times
- minimum switch-off times
- minimum switch-on times
Taken into account.
Example:
Vorlauf soll 5 sein Nachlauf soll -1 sein MinAusZeit soll 3 sein
ZeitprogrammX:
|---------------| |------------------------| |----------|
ein aus ein aus ein aus
ZeitprogrammX_real:
|-------------------| |---------------------------------------------|
ein aus ein aus
Note: The new time programs are always named the same as the original time program with the addition “_real”.
The new time programs contain a data point whose name is composed of the time program name and “_DP”.
