XUMG503: Janitza Electronic UMG-503 Modbus RTU Protocol Driver v10.0


XUMG503: Janitza Electronic UMG-503 Modbus RTU Protocol Driver

General Information:


XUMG503 driver allows you to connect to UMG-503 Universal Measuring Device manufactured by Janitza Electronic Gmbh.

This driver is a modified version of the XMODBUSB driver and uses the Modbus RTU protocol to request data from the meter in IEEE754 floating point format and IEEE754 double format.

This driver integrates several Modbus RTU requests into one single request that returns a set of values that are relevant for a monitoring application.

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.

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. 19200,N,8,1 is the recommended setting.

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 any of 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.
