Ethernet communication

For this communication method, use the MbusTcpIpNetwork component instead of the MbusSerialNetwork component and set up the Ip Address in the properties as required for the unit.
 
NOTE: This includes the port number, which follows the IP part, prefixed by a colon.

Refer to the manual.

Use the built-in Web Server to obtain a set of example readings from the meter, for use in establishing what the manufacturer’s properties represent.

ABB Ethernet Meter

This meter uses manufacturer-specific data, a primary address of zero (0) and the FC bit toggle. A double discovery is required.

For a double discovery, first carry out a discovery, then add the device (do not discover the history or points), set up device properties (see following), remove the device from the network database (a device action), and carry out another discovery. This ensures that the Fc Bit is in the correct state and in agreement with the meter. Now discover the history or points.

Device properties should include: Device Cycle Quantity = 1, Reset Required = true and Fc Bit In Use = true.

After reading the data, examine it and set up the scaling factor to give the correct readings. The scaling factor is defined by the Conversion property in the proxy extension of each point. For example, you might choose a Conversion of Linear with Scale and Offset instead of the default settings.

  • Manufacturer Specific89 was found to represent the Frequency and had to be rescaled by 0.01.
  • Manufacturer Specific24 was found to be the Power Fail Counter no rescaling required, left at 1.0.
  • Manufacturer Specific96 was found to be the Power Factor value, and had to be rescaled by 0.001.
