SECTION 16 Application Analysis / Performance Monitor
Summary Tab The 'Summary' tab provides an overview of the
application data including any warnings or errors found.
Warnings Tab The 'Warnings' tab identifies specific problems found with
the application and may offer suggestions for resolving
the problems.
It many cases, it will also be possible to go straight to the
source of the problem by accessing the popup menu
associated with the item, allowing the problem to be
resolved directly from the 'Analyse Application' dialog
box.
Network Tab The 'Network' tab provides information specific to the
selected network configuration. Where more than one
network is configured, each network can be selected
independently from a drop-down list.
PLC Tab The 'PLC' tab provides information specific to the
selected PLC. Where more than one PLC is configured,
each PLC can be selected independently from a drop-
down list.
Pages Tab The 'Page' tab provides information specific to the
selected page. Where more than one page is configured,
each page can be selected independently from a drop-
down list.
This following information explains what data will be analysed when the
'Analyse Application' feature is run.

Inputs On Request
The total number of points that are always
updating whether they are on display or not - this
should be kept to a minimum to reduce bandwidth
use - only use this if the point value is required by
scripts or other actions on pages where this point
is not otherwise used.
The percentage of points that are always updating
- this should be reduced in favour of update on
display
This is a count of points that are set to Always
update at the specified rate. It is best to have a
small number of different update rates as this
helps CX-Server to optimise. Whilst good to have
a low number of different update rates it is also
worth remembering that the more updates per
second the more bandwidth is used.
The total number of inputs that are on request.
These are potentially less efficient than an 'on
interval' - a single point being requested is not
optimised by CX-Server when sending to a PLC
many points at the same interval can be sent in the
same message with negligible overheads.
