Hi all,
I have an UDT tag with some alarms and I’d like to configure the display paths as an expression, but I am having some troubles… I would to concatenate an UDT parameter and a tag value (string), then I tried:
{[~]Alarm_Configuration/Alarm_root_path} + {id}
where “Alarm_root_path” is the tag, while “id” is the UDT parameter.
With such expression the system return (tag diagnostic): “Error forwarding data: Duplicate entry”
I’ve tryed several solutions (also using cast to string, concatenate() and so on) but they didn’t work. However, using the expression tab I noticed that:
{[~]Alarm_Configuration/Alarm_root_path} --> works
{[~]Alarm_Configuration/Alarm_root_path} + “/test” --> works
{id} --> doesn’t works
Then I am quite sure that the problem is the {id} expression, but I can’t figure how to fix it…
Thank you,
Alessandro
