Question: Mass Modbus Tag Import
Is there a way to bulk-import Modbus tags in WinCC OA?
The Modbus driver documentation doesn't mention any import support, unlike S7 which has it built in. For a use case involving thousands of Modbus tags, manual creation isn't feasible.
Does Mass Engineering or ASCII Manager support Modbus peripheral address configs? Or would a CTRL script be the way to go here?
Any pointers appreciated.

Hey, yes ASCII manager would be the way. You can try to create one address manually and export the tag, then mass create everything and import back.

Just check Parameterization and in drop down you need _address and _distrib (will give you which driver number you are using)
If you have the modbus tags already in a format, that is easy to read with a CTRL script then it also an option.
But the tab separated format of the ASCII manager also allows mass parameterization with a spreadsheet program especially if only numbers need to be changed in a consecutive serie
