Q 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.
Q 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.
Q How do 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 “Temper 273” rather than creating a new
“TemperatureCelsius” memory point.
Boolean expressions can easily written to operate on bits within a word e.g. nFlags & 0x02 will be
TRUE if bit 2 is set or FALSE if it not. This eliminates the need for additional memory points and
processing.
Q Can I use token disks with USB Floppy drives or in high capacity LS120
Disk Drives?
The token copy protection is no longer supported. The software tokens have proven to be
incompatible with some USB floppy drives and the high capacity LS120 Disk Drives. If you need to
remove a software token use the network to conduct the token transfer, by sharing a floppy drive
from another machine.
