German Text in OPC UA Alarm ALM_STATE Structure, ALM_REGISTER

Hallo everyone,
i have implemented a modular OPC UA Alarming-System using the Systems fb “ALM_REGISTER”.
It works fine, but i am having trouble showing special characters, especially in German Language (for example: äüö etc).
The ALM_STATE structure has a Message string which is used for that.
image.pngsince a string is defined as ANSI Coding, special Caracters shut be no problem.

but at the OPC UA Client special characters cant be shown. The OPC UA Alarm-Message has the OPC UA LocaleId “en” i dont see a way to set the correct id (“de”) for the alarm Message.
image.pngThe ALM_STATE Structure has a LANG element, but the online help says not to use it…

Is there any known way to solve this problem?

Hi Harm,
thanks for your request.
The “LANG” option is currently not implemented, but the issue occures as the string type seems not be able to handle the ANSI extension - only ASCII.
I’ll check this with the product owner, but as they are currently on the SPS trade fair this might take until next week.
Keep you posted.

BR,
Frank

Hi Frank,
do you have any news about this topic?
Due to European standards, I am obliged to use German alarm texts, So a nice Solution for special characters would be great.
With kind regards
Harm
