      Communicating with Q.bloxx Modules via Modbus RTU

      Acquiring data from Q.bloxx modules via Modbus RTU

      Modules can be accessed directly via Modbus RTU. Module addresses can be configured either using DIP switches or with ICP 100. This address also serves as the Modbus ID for the module.

      Setting the module address via DIP switches

      Setting the module address using ICP 100

      1. Connect the module directly to the PC using a USB-to-RS-485 adapter.

      2. Click the Scan button to detect the module.

      3. Once the module is identified, change the address in the "Module Settings" tab.
