Landis+Gyr

Teleport can connect to Landis+Gyr power meters fitted with the E65C CU-XE module. You can connect using Modbus RTU using the RS485 serial interface or Modbus TCP over ethernet, which is recommended. More configuration information can be found in the official documentation.

Modbus TCP over ethernet (recommended)

1. Connect the ethernet cable between the ETH1 port of the Teleport and the LAN port of the CU-XE module. If the LAN port of the module is already occupied (e.g. connected to a router), navigate to our appendix for instructions on how to integrate with a router.

2. In case Teleport connects directly to the meter, open the web interface of the module and navigate to Communication and Network. Configure the following settings, with values as described in Static IPs for a direct asset connection.

   • IPv4 Configuration: Static
   • IP Address
   • Subnet Mask
   • Gateway

3. Enable the Modbus client by opening the web interface of the module and navigating to Protocol Conversion > Clients > Modbus and clicking the checkbox.

4. Configure the modbus map, shown in the table below, if that is not already done. All registers should be Holding registers with data type Float and register length 2.

Modbus RTU over RS485

1. Connect the serial cable between the serial port of the Teleport and the serial port of the CU-XE module. The serial port is an RJ45 socket, where the wires must be connected as follows:

   • RS485_NEG pin on Teleport to pin 5 of the module
   • RS485_POS pin on Teleport to pin 6 of the module
   • GND pin on Teleport to pin 1 or 7 of the module
   • Module bus should be terminated with 120 Ohm termination resistor

2. Enable the Modbus client by opening the web interface of the module and navigating to Protocol Conversion > Clients > Modbus and clicking the checkbox.

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 map, shown in the table below, if that is not already done. All registers should be Holding registers with data type Float and register length 2.
