Hi,
I try to import a modbus table from a schneider PLC. When I try to import the file, I get the following message :
The value of 'prefix' is not between 1 and 12 characters long.

Is it possible to get a prefix with more than 12 characters? Why is there any restriction?
Thank you!|
The import and export on the modbus mapping pages is meant for Ignition (created) mapping. It does not support importing from 3rd parties.

Most recommend to not use the mapping feature at all, instead manually create tags using the following format:

I only use the mapping feature if I have a large amount of consecutive tags.
