ABB TransGuard-TG3 Series Communication using LabVIEW FPGA

[Michael_Smith]

Hi everyone,

I'm currently working on programming an ABB TransGuard-TG3 Series surge protection device. I am trying to interface with it using MODBUS RTU communication and am developing custom code in LabVIEW FPGA.

I'm wondering if anyone has experience in:

Configuring MODBUS RTU for this device.
Using LabVIEW FPGA for MODBUS RTU communication.
Handling any specific challenges that arise when working with ABB's TransGuard-TG3.
Any code examples, resources, or advice would be greatly appreciated!

Thanks in advance!

See Modbus Communication Reference Example for cRIO

I would recommend testing using QModMaster as the Test Panel with a USB-RS485 (a third-party one will do) to figure out what function and data ABB TransGuard-TG3 will response to.
