EMH

Teleport can connect to EMH power meters fitted with the Interface Module XC Modbus. You can connect using Modbus RTU using the RS485 serial interface.

Modbus RTU over RS485

1. Connect the serial cable between the serial port of the Teleport and the serial port of the Interface Module XC Modbus.

2. Configure the Buad rate on the meter using the EMH COMBI-TOOL-Software.

   • Navigate to the following menu: Meter —> Interfaces —> Electrical supplement / aditional interface
   • Select a fixed baud rate

3. Teleport is configured to use the following default Modbus interface configuration of the module (let us know if you use a custom configuration):

   • Device address: 1
   • Baud rate: 9600
   • Stop bits: 1
   • Parity: none

4. Configure the Modbus protocol, if that is not already done. All registers should be Holding registers with data type signed integer 32 and register length 2.

Note

With the Anexo Modbus mapping, the current measurements are not included in the report as the current is only available with an absolute value. Therefore, this meter with Anexo mapping is not suitable for our current-based Control strategies

Modbus protocol

Tip

The Modbus map below is the default Modbus map as described in the Interface Module XC Modbus manual. The Teleport also supports the default map programmed by Anexo.
