DPE'S comming of PLC to configure alerts

[ccmelo]

Its possible to defined a DPE for the limiting values on the alert handling?

In my case, I have the limiting values coming from PLC and I need to configure the alert in WinCC OA using the parameters from PLC.

There is no standard solution to assign thresholds defined in the PLC to the _alert_hdl config.
If you want to apply the configuration from the PLC you have to implement a function on your own which maps the values from the PLC to the _alert_hdl configuration.

As a workaround you could generate the alerts in the PLC (a boolean for each alert range) or use a multi-instance alert and raise/lower the alerts with scripting.
