Fieldbus Protocols

Fieldbus Protocol Support

The T1.B100 has 4 serial onboard ports (Serial Port 1 to 4) as well as an expansion slot for serial expansion cards (Serial Port 5).

Supported fieldbus protocols

  • Modbus

  • Transparent Mode

  • Application usage (CODESYS, Node-RED, etc.)

Switching between Modbus and Transparent Mode

  1. Enable Advanced Mode

    • Click the gear icon ("Settings") in the top right.

    • Enable "Advanced Mode".

  2. Access to new applications

    • Open the "Applications" menu.

    • You should now see two new, non-uninstallable applications:

      • Modbus Mode

      • Transparent Mode

  3. Select the mode for each port

    • Navigate to the "Serial Settings" menu.

    • Find the "Fieldbus" section.

    • Select the desired mode for each port:

      • Modbus Mode

      • Transparent Mode

Important notes

  • The new applications (Modbus Mode and Transparent Mode) are permanently integrated into the system and cannot be uninstalled.

  • You can flexibly decide which port uses which mode.

  • The Transparent Mode enables the use of serial interfaces over the network, which is particularly advantageous for applications in building automation and industrial control.
