Has anyone seen this error before? I have a device simulator programmed and in the Status > Logs it's showing the following error as well so I think the simulator is at the root of it:

That means you've configured something in the DB=>OPC direction, and that OPC target is read-only. Or it's an Ignition tag set to read-only.

Or you are triggering from a read-only OPC source and you've configured the transaction group to reset it.
