9 Configuring events
Events are expressions that trigger actions. Expressions are equations
containing tag values, mathematical operations, if–then–else logic, and
other built–in RSView32
functions. Actions are RSView32
commands, symbols, or macros. An action could, for example:
initiate a snapshot of tag values using the DataLogSnapshot
command
display an error screen using the Display command
change a tag value using the Set command
execute a VBA program using the VBAExec command
This chapter describes how to use the Events editor to create events.
It does not describe the expressions used to produce the event’s actual
function, or the events associated with VBA programs. If you do not
know how to use expressions, see Chapter 14, Creating expressions. For
information about events in VBA programs, see the Help topics that
relate to the RSView32 Object Model.
How to use multiple event files
You can create multiple event files. At runtime, up to 20 event files
(containing a maximum of 1,000 events each) can run simultaneously.
Use multiple event files to:
group events that need to be evaluated at different rates
group events that are active only when a particular graphic display
is active
