128 CoDeSys 2.3 Runtime Environment
Why does the visualization element "TREND" in the Web visualization only
work "Online"?
The following settings must be selected for the visualization projects: Resources
tab > Target system settings.
Activate "Web visualization" and "Trend data recording within control."
Otherwise, the trend data are saved on the hard drive of the CoDeSys
development computer. This makes a permanent connection between the I/O-IPC
and the CoDeSys gateway necessary. An interruption in this connection can lead
to unforeseeable behavior of the I/O-IPC.
In the TREND configuration dialog, you can choose between the operating modes
"Online" and "History." The I/O-IPC only supports the operating mode "Online"
for visualization projects since it is not possible to configure the maximum size
(quota) of the trend files (*.trd). An uncontrolled expansion of trend files can lead
to unforeseeable behavior of the I/O-IPC.
In most cases, the use of the "HISTOGRAM" visualization element is the better
choice, as this gives full control over the time and number of measurements and
thus the amount of memory required.
What needs to be observed when the visualization element "ALARM
TABLE" is used in the Web visualization?
The status of this component is best described with "Add-On", i.e. an extra that is
free of charge and without warranty.
The following settings must be selected for visualization projects: Resources tab
> Target system settings.
Activate "Web visualization" (checkmark) and "Alarm handling within control".
Otherwise, the alarm data is processed on the CoDeSys development computer.
This makes a permanent connection between the I/O-IPC and the CoDeSys
gateway necessary. An interruption of this connection can lead to unforeseeable
behavior of the I/O-IPC.
