Setting Modbus TCP Unit ID in Device Configuration

I’m using Ignition 7.9.9 on Windows Server 2016.

I’ve set up my Modbus device and can poll data from it by setting the Tag’s OPC Item Path like so:

[OPC Device Name]243.HR1

Which would poll register 40001 of the device with unit ID 243.

My question is, is there a way to set the unit ID when you configure the device’s settings in the gateway? That way instead of having to manually specify the Unit ID for each tag I could just do:

[OPC Device Name]HR1

No, it’s part of the address. A single driver connection can address tags from more than one unit/slave id.

Thanks Kevin, that’s what I figured, but I wanted to make sure.
