Week schedule

If a TAC Xenta controller is connected to a supervisory system like
TAC Vista, another indication may appear in the alarm list. An
asterisk (*) in front of the signal name means that the alarm is
blocked, that is, information about changes between alarm on and
alarm off will not be sent to TAC Vista.
The alarms will, however, be listed on the OP as usual.
The blocking request is set/removed from TAC Vista.
Example:
AH02
*SF1
SUPPLY FAN STOPPED
99-JAN-15
Note! Starting with TAC Xenta System program v 3.4 this blocking function
has been changed. The alarm information will be sent to TAC Vista, as
any normal alarm, but it will not be displayed on the OP.
Please note that TAC Vista will store the alarm event in the historical
log, even if alarms of priority 0 are not displayed in the alarm list.
The operating hours for a selected object can be adjusted by altering
one or more time channels. This can be done from the operator panel.
The number of week schedules available for a specific time schedule
is defined in the application program.
The following is an example of an object (AH02) controlled by three
different schedules. The object is active 08:00–12:00 and 13:00–17:00
on weekdays and 08:00–12:00 on Saturdays. The example shows how
to change operating hours on Saturdays to be 08:00–13:30.
Example:
