Landis & Staefa Division Function DATE 2-71
On entering a new date the Server will accept various formats provided the input is
unambiguous.
The associated day is automatically set by the Server after this answer is terminated
with <CR>.
Date =3-1-96/We: 3-Jan
3-Jan-1996
3-1-96
3.1.
etc
If the year is omitted the VISONIK DCS automatically assumes that year given in the
prompt:
Date =20-11-95: The prompted year is 1995
New entry : 20-11 ---> The year remains at 1995
The format of DATE OUTPUT can be specified with parameter DAFO in point type SY.
Update date & Time Reactions =NO
If a user answers "YES" and the time is advanced (for example reset after a Server
halt), all those Time and Date Reactions which should have taken place during the
skipped period are updated. To avoid multiple unnecessary switching actions the
Reactions are only updated to the point until there is again agreement between the
actual updated Reaction entries and the plant's set status.
In the DRR register the time is newly adjusted at the next call-up.
In the TRR register a time reset has no effect.
Any units of time not specified are set to zero.
Time =16:48:10: 17: ---> 17:00:00
12:30 ---> 12:30:00
etc.
After changing Date and/or Time the internal Server's clock starts at the new time.
The current weekday is calculated automatically from the entered date and is reset
taking into consideration any entries in the Special Day Register (SDR). The resultant
day together with the time determines the execution of Time Reaction in TRR.
Date/Time changes are acknowledged on all DevINI set terminals with a message in the
following form:
HAND 17:00:01 Time changed from 19-10-95/Th 16:48:10
to 19-10-95/Th 17:00:01
The new date and time will also be output on all output terminals. If the new date has
been programmed as a special day the weekday (Special Day) as defined in the SDR
entry is printed in brackets next to the actual date.
