  • Modbus TCP setup
    • Modbus Port - the port that the Vista Touch meter will communicate with your system via TCP
    • Modbus Timeout - the amount of time the master will attempt to send a message

  • Modbus RTU setup
    • Slave ID - the address of the device, it can take a value from 0 to 247
    • Baud Rate - the speed of the data transmission
    • Number of stop bits
      • Allows time for the reception and processing of the current byte and the preparation for the next byte
