I have multiple units with the same software running on the hardware. Is there a way to make a tag that uses a device currently viewed, or being polled?
This might not be exactly what you’re asking, but since all the tags would have the same addresses for each device you could make a UDT where the device name was a parameter and the OPC item path for all the tags in the UDT are built using that device name.
That sounds about right, what is a UDT and how do I get the variable replacement. Also, I want the opc server to still grab all the tags from all the devices for BI purposes.
