Application Analysis SECTION 16 Application Analysis / Performance Monitor
238
Total ActiveX Objects This is a count of the total number of ActiveX
objects used in the project, this includes objects
which are used more than once. Using ActiveX is
a great way of adding advanced functionality to
your application but it carries the risk that the
component used may not be as reliable as
required.
Total Alarms A count of the total defined alarms on the system -
this is limited in ME so this gives an idea of if the
limit is being approached. Many alarms also make
an application harder to manage and maintain so
keep this number as low as possible and avoid
unnecessary alarms.
Total DDE Points DDE is an antiquated technology and is prone to
problems especially when used with non English
characters. Any DDE points should be removed
and an alternative used instead.
Total Graphical Objects The total number of objects used on all the pages
in the project. The more objects that are in the
project the slower larger it is on disk and the longer
it may take to re-draw a page. This is especially
key when using an IPC where space and power
are at a premium.
Total Memory Points The total number of points that are not on an
external device. These are the most efficient
points as they don't consume network bandwidth,
Total OPC/Other Points The total number of points that are external to CX-
Supervisor using a comms interface such as OPC
or on another CX-Supervisor runtime.
Total Pages This is the total number of pages in your project
(including pop up pages). This is limited in ME so
this gives an idea of when you are approaching
this limit. Too many pages can make a project hard
to maintain so this should be kept to a minimum.
Total PLC Points The total number of points in the application that
are on a device
Total PLCs The total number of PLCs in this project - Any
PLCs used on the same network will obviously
share bandwidth. If there are more PLCs here than
you expect, check the PLC configuration and
make sure you've not defined a duplicate PLC.
Total Points The total number of points in the project.
Obviously for simplicity and performance this
should be kept to the minimum you require.
Total Regular Interval
Scripts
Regular interval scripts indicate poor design
decisions. Running a script on a regular interval
can be inefficient and cause a significant increase
on local CPU usage. If regular interval scripts also
update points on devices this can lead to
increased bandwidth use. Consider using an 'on
condition' script instead.
