7.4.10 Operator button
This displays a user pushbutton. The legend on the pushbutton, and the task it is to carry out, are de fi ned in
the button con fi guration. If the text is too long for the width of the button, the text is truncated (e.g. Reset
Ave...). Possible tasks are as follows (assuming that the relevant options are fi tted):
1 Edit the threshold (setpoint) setting for alarms 1 to 4 for point N
2 Reset Maths channel N
3 Edit Maths constant N
4 Preset Totaliser N
5 Preset Counter N
6 Start/Stop Timer N
7 Initiate Demand Write N
8 Set output channel N to default values.
In all the above, N represents any number between 1 and the maximum number available for the relevant
type of point. (Point is an umbrella term for input channel, a maths channel, a totaliser, etc.)
When the button is operated a ‘con fi rmation’ page appears allowing, for example, the value of a constant to
be edited before the ‘Apply’ button is operated.
Notes:
1 If the point being accessed is not suitably con
fi gured, the ‘con fi rmation’ page is blank. For exam-
ple, if the Operator button is con fi gured to change, say, the threshold (SP) of Alarm 2 on Channel
6, and either Channel 6 is Con fi gured ‘Off’, or alarm 2 is ‘Off’, then the Con fi rmation page will not
have a con fi gurable area allowing the user to enter the required new value.
2. Any signing or authorizing that normally applies to the item being edited, also applies when changes
are being made by means of the Operator button.
7.4.11 Event Button
This displays a pushbutton, to be used as a source for an event. The button name, its action (latching or
unlatching), and whether or not the operation of the button needs signing or authorizing are set up in Event
Button con fi guration, described in section 4.3.7 . The actions taken when the button is operated are set up
in Event con fi guration, described in section 4.3.6 . Signing and Authorizing are as described in section 4.4.2
(Management).

7.4.12 Image
This allows a GIF (Gif87a format only) or JPG image fi le to be loaded from (e.g.) a Compact Flash card. Once
this has been done, bargraphs, text messages etc. can be superimposed on the image.
Notes:
1 Only user screens 1 to 6, may have images embedded in them, and the size of each image may not
exceed 250kB (see also note 3). Does not apply to Bridge-only screens (25 to 124).
2. It is recommended that ‘abs_pxl’ be selected as width and height units, before an image is loaded.
The use of any other units signi fi cantly increases the time taken for the loading process to complete.
3. For user screens 1 to 6, the physical size of the image may not exceed 1024 pixels wide or 768 high.
Any attempt to load am image larger than this results in a ‘ User Screen Image Error’ message asking
that the image size be reduced. The size constraint does not apply to Bridge-only screens (25 to 124).
