  • Page 7: 1-Wire Interface

    However, it is not suitable for long cable runs or environments with high electrical noise. The TCG140-4 supports connecting up to a maximum of eight sensors, whether they are 1-Wire or MODBUS RTU. All Teracom 1-Wire sensors are compatible with this device. Once connected, sensors are automatically detected, and the corresponding measurement dimension is assigned.

  • Page 8: Digital Inputs Connection

    To maintain signal integrity, it is essential to use 120-ohm line terminators at both ends of the RS- 485 bus. The TCG140-4 includes one terminator and should be installed at one end of the line, leaving the other end for the user to terminate.

  • Page 11 7. Initial setup via USB The initial setup of TCG140-4 is performed using a computer with Windows 10 or a newer version of Microsoft Windows. After powering up the module, connect it to the computer using a USB cable. Once connected, the operating system will automatically begin installing the necessary drivers for communication with the device.

  • Page 12: Monitoring Page

    There are two sensor sub-sections on the page: one for 1-Wire sensors and another for MODBUS RTU sensors. The TCG140-4 supports up to eight sensors, which can be connected to both interfaces in a random ratio. This ratio is set in the “Sensors Ratio Setup” section on the Setup -> Sensors page. By default, the number of MODBUS RTU sensors is set to 4.

  • Page 16: Communication Setup

    The TCG140-4 supports MODBUS RTU sensors with a response time-out range of 10 to 500ms. By default, the response time-out for a new sensor is 100ms. It is recommended to use the shortest response time supported by the sensor’s manufacturer to optimize performance. The total system response time-out is the sum of the selected response time-out values for all configured sensors.
