Instructions

  1. Download and install the following software

    1. KUNBUS Scripter: https://www.kunbus.de/downloads.html
      (or see attached ZIP)

  2. PuTTY: https://www.putty.org/

  3. QModMaster: https://sourceforge.net/projects/qmodmaster/

  4. Connect the USB-PiBridge Plug with the Serial Gateway

  5. Connect the 24V power supply. The power led should light green

  6. Connect the PiBridge Plug via USB to your PC

  7. Open the Scripter and load the script “ScriptExample_64Registers.pbs” see top of the page.

  8. Go to File → Settings and enter the serial connection details

// // KUNBUS GmbH // 07.08.2019 // Example Script for a Gateway Serial Rx Module. // // This script demonstrates how to receive and transfer // a variable amount of up to 64 Registers (2Bytes) to a partner // Gateway Module. // // We define a serial protocol as follows // // Byte | 1 | 2 | 3 | ... | 129 | // -----+-----------+--------+--------+-----+----------+ // Desc | Registers | Byte 1 | Byte 2 | ... | Byte 128 | // // On the Partner Gateway Modbus-RTU the data is mapped as follows // // Reg. | 1025 | 1026 | 1027 | ... | 1091 | // -----+--------+-----------+---------+-----+---------+ // Desc | Status | Registers | Word 1 | ... | Word 64 | // // Attention: Command "setMBReg(address, parameter);" writes // the value in parameter in the register address. The parameter // can be a constant, variable or an array. If the parameter an array is, // must be the number of occupied bytes a multiple of 2.
