I'm having a time setting up a Shark Power Meter configuration in Ignition. I'm unsure which address configuration to use. The meter is connected. Any help would be greatly appreciated. I'm new to the Modbus protocol.

Create **two** OPC Tags in Ignition, with datatype "float4". Set their item paths to `[deviceName]0.HRF1000` and `[deviceName]1.HRF1000`.

Adjust the advanced settings on `deviceName` for zero-based addressing and word swapping until on of those works and yields the expected value.

Extrapolate from there.
