If the network connections are in the same network segment you cannot be sure that both network connections are used, because the OS decides over which connection it sends the data and the WinCC OA will close the second connection from the same source IP address.

I have the warning "Unsupported data type 589824" in the log. but how to know what is this data type XXXXXX ?

Convert the value to hex (0x00090000), search for this value in '<API_ROOT>/Libs/Basics/Variables/Variable.hxx' and find 'BIT32_VAR'.

Values sent by 'DrvManager::getSelfPtr()->toDp(...)' are not affected by 'forwardDp(Type)' config entries. They are simply discarded from the passive driver.
For a driver (watchdog) status use 'dpSet(...)' to set an internal driver (watchdog) datapoint element.

Use 'StrUtil::catgets'.

Driver: Asked and answered in topic OPC UA method call.

The (classic) S7 driver could also be used to connect to a S7-1500 in compatibility mode.

In case the contents are scaled you could get the 'window size' by multiplying the width and height (as returned by panelSize) with the zoom factor.

The additional texts could also be set with the 'curveValuesTexts'. For a trend curve no dpe is needed, you could for example put the state information in a trend curve. Read the values from the trend, make the json strings event values from this data and put these in the event curve. A control mana...

Another option would be to:

• define an event
• connect to this event
• trigger this event

The benefit of using an event is that the script context is the same regardless of from where the event is triggered.

Also the 'strwalk' function should be able to read a single Unicode character.
