Setting Modbus TCP Unit ID in Device Configuration

Ignition
1

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.
