Change effective period:
This operation allows the user to change the effective
period of the schedule, thereby enabling and disabling not only single days but
the entire scheduler unit.
Edit day patterns of exception days:
This operation allows write access to the
contents of the calendar which is connected to the scheduler unit. The user may
add, remove, and edit entries in the calendar which define the days on which a
certain exception schedule is active. Also linked to this access right is the setting
of the exception day priority.
To change the minimum required access level to perform one of these operations, select the
operation from the list and select the desired access level from the dropdown box below the
list. Keep in mind that the minimum access level specified for the entire control on the
Common
property page must be satisfied in addition to the levels specified here.
9.5.10 Alarm-List Control
The alarm list control is a specialized control to display a list of alarms from an alarm
server or alarm client data point. It is possible to connect more than one alarm data point to
the same control, in which case the control will display a list of all alarms from all
connected points in chronological order.
The control always displays the newest alarm at the top with older alarms following further
down. At the bottom of the control is a navigation bar which displays the number of pages
the list currently uses and allows to navigate through the pages.
Alarm entries which may be acknowledged are shown with a small ACK button at the right
end of the alarm entry. Pressing this button will send an alarm acknowledgment back to the
reporting alarm server and change the color of the button. Once the server received the
acknowledgment, it may send an updated alarm status and the button or the entire entry
may disappear, depending on the configuration of the control.
The default information displayed for each alarm is the date and time the alarm was first
reported, the type of alarm, the current state of the alarm and, in the second line, an
identification of the alarm source as well as a description and possibly the value which
caused the alarm. The layout and display of the various information fields can be freely
configured using the two lists on the
List Entry Setup
property page.
The list at the very left contains all available information fields and, at the end of the list, a
special item to insert a line break as well as one item to insert custom text. The buttons
between the two lists are used to add, remove, or change the order of items in the right list.
The list to the right defines the final layout of the entries in the alarm control. While
changing the display list, the effect can be seen immediately on the LCD preview.
Depending on the underlying network technology and the fact if the alarm was reported by
a local or by a remote alarm server, not all of this information may be available, so that
entries may be missing some of the information. Some information items, like the
acknowledge time and source or the clear time become available during the life cycle of an
alarm. If not yet applicable, such fields may be shown as dashes.
On the
Alarm Log
Control property page, the following options can be set:
ISO-8601 date format:
This option selects the ISO-8601 specification to display
dates, which is a four digit year, a two digit month, and a two digit day, all
separated by hyphens (YYYY-MM-DD).
DIN-1355 date format:
This option selects the German DIN-1355 specification to
display dates. In this format, the order is day, month, and year, separated by
decimal points (DD.MM.YYYY).
