This list shows the total number of device points at
each update rate - these should be kept to a few
well chosen update rates - many points on very
few update rates that are not more frequent than
absolutely necessary
These indicate that the cdm file has become
corrupted. CX-Supervisor auto generates the cdm
file so if this has become corrupted for some
reason, you can close all Omron software and
delete the file. When you re-open CX-Supervisor
developer the file will be re-generated.
This is the percentage of the network used in the
worst case (Theoretical max bandwidth) scenario.
This is based on an assumption of bandwidth for
the particular network and does not take into
account network traffic or other variables.
This is the theoretical maximum number of bytes
per second of updating points - this is a better
gauge of bandwidth use.
This is the theoretical maximum number of points
that will update each second - the higher this
number the greater chance of comms problems -
this value is very dependent on data type though
so is not the best reflection on bandwidth use.
Some points are arrays so the element count
reflects the number of elements updated per
second. Again this is independent of data type but
when compared with Max Points/Sec can give an
idea of how many points are actually array points.
The total number of points that are output to the
device whenever the value has changed
The total number of points that are only output to
the device when request - this can be more
efficient if the value changes frequently but the
device doesn't need to be notified of this
frequently,
This indicates a big problem - you are using a
point in a script or in some other action which
doesn't exist - this will fail if this script or action
ever runs.
This is a measure of all the points updating all the
time and all points on display for the worst case
page in the project. This figure should be kept as
low as possible and within the bandwidth of your
network.
