I am working on a development project which requires me to add multiple OPC-UA devices (Modbus-TCP). I am essentially adding 120 of the same device with the device name incrementing (i.e. Device1, Device2, etc...). I was doing some digging in hopes of discovering a method for me to efficiently add 120 of the same device. I looked in the folder structure where ignition data is stored and found the folder path C:\Program Files\Inductive Automation\Ignition\data\opcua\devices, but nothing was there. Is there any way to achieve what I want? Thanks!
