XGAVWM14: Carlo Gavazzi WM14 and CPT Basic Serial Protocol Driver v10.0


XGAVWM14: Carlo Gavazzi WM14 and CPT Basic Serial Protocol Driver

General Information:


XGAVWM14 driver allows you to connect to Carlo Gavazzi Controls meters of the WM14-DIN BASIC, WM14-96 BASIC and CPT-DIN BASIC series using the serial communication protocol Ver. 3 Rev. 0.

WM14 and CPT are provided with a RS485 serial interface. The underlying communication protocol is an adaption of the Modbus RTU/JBUS protocol.

The data format is fixed:
  • 1 start bit

  • 8 data bit

  • 1 stop bit

  • 9600 baud

  • Parity: none

  • Make sure that the controller station address, baudrate, parity, databits and stop bits are correctly configured in the driver and matches those used by the meter.

    This driver expects that you connect to your device through its serial port. The device should behave as a slave in your RS-232/485 network. This driver supports serial-over-ethernet so you can alternatively use some kind of transparent ethernet/serial converter to reach your device using your LAN.

    If you cannot communicate or if you are using RS-485 to connect to the device, you should set the RTS signal during the communication. This can be done by setting the RTSEnable argument when calling the read and write methods. If you still cannot communicate, check that your RS-485 cables are not inverted.

    Licenses

    The licenses of all our drivers are unlimited in terms of the number of machines where they can be used, the number of I/O that can read or written, and the number of components that can be included in each application.

    After purchasing a license, the owner can use the driver and all its components to assemble and distribute as many applications to as many users as needed.

    The license owner retains full control of his applications by deciding himself what target machines can they be run at. For this, each driver is provided with two runtime license management tools: GetPCId.exe and MakeLic.exe.
