In graphics editor select text tool from palette and type text e.g.
Temperature = ##.### C
The # after the decimal point indicate the precision of the real number
display, e.g. to 3 decimal places. Finally select animation editor and
animate with "Display Value (Analogue)" and assign the point name e.g.
TEMP.
• Which Operating System should I use?
Windows XP Professional.
Windows NT, Windows 2000 and Windows XP Professional all offer the
best stability, reliability, multitasking, security and DCOM support.
On the same spec machine, Windows NT is actually up to 10% faster,
probably as it has the least developed code although Windows 2000 and
XP are faster on their appropriate minimum specification machines.
Windows 95, Windows 98 and Windows ME are no longer supported.
• How do I optimise the use of Files?
When closing a file using the 'CloseFile' script function, if TRUE is passed
as a parameter e.g. CloseFile(TRUE) then the blank spaces at the end of
each line will be removed, thus reducing the size of the file. Care should
be taken if the file is being used by multiple systems over a network drive.
• What is the limit of points in a group?
There is no imposed limit but it is recommended to limit about 1000 points
per group. There are two main reasons for this:-
• There is a physical limit on how many lines of text the actual list can
display. This is dependent on the height of the text. With large text
you may even find that 1000 is too many.
• When a group is selected the point list is refreshed and re-sorted.
The sort algorithm takes longer if it has a large list to sort. This is
normally quick but if the list is large and the points are already in the
correctly sorted order in the database, then it can take a while
because of the way the sorting algorithm works.
• Why does setting slider value result in erratic movement of slider
action?
The movement of the slider bar can appear to return to its previous setting
once it has been re-set. After setting the slider to a value, it will read the
actual value from the PLC, this value is then shown in the slider, resulting
in the slider moving from the re-set value to the old value, the slider then
starts to move towards the re-set value. This actually better reflects the
current value in the PLC, but can be undesirable.
In this case de-select the "Immediate update on slide move" option in the
slider wizard to prevent it.
• How do I optimise my use of animations?
Animation actions (from the Animation Editor) can be applied directly to
the objects being animated. This means that you don't have to define lots
of memory points to hold intermediate values. Just link the appropriate
action to the object (using the Animation Editor) and enter the required
expression. For example using expression "TemperatureK + 273" rather
than creating a new "TemperatureCelsius" memory point.
