and assigned a user address. This process thus defines which user addresses are to be referenced by the time program.
Up to 20 time programs can be defined for each Excel 500. The time programs are extremely flexible. The switching points for a section of the system or building are usually combined in one time program. It is also possible to combine all datapoints in one time program.
The following steps can also be carried out at operator level 2 (read and limited changes) of the XI581 (not with XCL5010, Excel 100C), XI582, and
1)Daily programs are generated and given a name.
2)User addresses with a switching time and setpoint value or control state are entered in the daily program.
3)A daily program is assigned to each weekday in the weekly program section after the daily programs have been generated.
4)This weekly program is automatically copied for each week in the annual program.
The generation of an executable time program is now complete.
If, on a certain day in the annual program, a daily program differing from the one specified in the weekly program is to be used, this new daily program can be entered directly in the annual program. The defined weekly program is not modified and continues to be used on those days which have not been modified, in any way, in the annual program.
Any changes to be made to switching times, setpoint values, or control states must be carried out in the daily programs.
The special day list is available. It contains a number of holidays; a different daily program can be assigned to each holiday. Once assigned to a holiday, the daily program will apply on this holiday every year. That is valid for holidays with fixed date (for example New Year’s Day or Christmas Eve) as well as for floating holidays (Ascension Day, Good Friday). The dates of floating holidays will be calculated automatically by Excel 500. If there are no entries, then the existing daily program of the annual program remains valid on that holiday.
