What version is this on? I remember an issue in the past where a bunch of UDT parameters were changed to string type. It may or may not be related to what you are seeing as I was not using the multi-instance wizard. I haven't run into that issue on more recent 8.1.x versions. ---

Sorry for digging up an old topic. I'm working with version 8.1.35 and I encountered the problem described above. All parameters given a value in the Wizard change their type to string. Any ideas how to solve this? ---

Unfortunately, there is no solution with the wizard. Most people simply write a script that builds a list of tag definition dictionaries for `system.tag.configure`. ---

Hello Thanks for fast answer. I expected this. That's why my team suggested using a script. However, I wanted to try this function for a smaller number of tags. ---

Actually, I just remembered that `system.tag.configure` also converts UDT parameters to strings. Where I've done this, I've used `system.tag.configure` to do everything **except** the parameters, followed by `system.tag.writeBlocking` to supply those. ---

In parallel, I corresponded with Support IA, who analyzed the operation of the Multi-instance Wizard. It turned out that the problem I encountered in version 8.1.35 was solved in version 8.1.41 and later. In the current version 8.1.42, parameter types do not change when creating an instance using the Multi-instance Wizard.
