Refreshing a lot of variables with the ISaGRAF debugger may lead to

a long response time.

The ISaGRAF target kernel can answer to just one communication

request in one target cycle. Obviously, the size of a request is

limited. When a large set of objects are displayed on the debugger

screen, they have to be handled in several communication packets.

This explains you need more than your cycle time to refresh the

complete screen.

The best solution to avoid this is to build dedicated lists of

variables, so the user can focus on exactly what he needs to spy,

and increase communication performances.
