1. Does the energy meter support communication module CU-P22?

To communicate with the energy meter, we need module CU-P22, which can be seen on the right side of the picture below.

2. How to psychically connect Landis+Gyr E650 with CU-P22 module to Reduxi Controller?

To connect over RS485 please see picture bellow.

3. Get the Physical device address (HDLC address)

For example:

Serila number: 73852799
HDLC device address: 2799+1000=3799

4. Add the device to Reduxi Configurator

First, you can log in to Reduxi Configurator using Reduxi Configurator via the browser.

1. Click Add Device

2. Enter Basic Settings

3. Select Communication Channel

4. Enter Device Configuration

Serial number = read it from the Iskraemeco energy meter

Physical device address: please see above

Logical device address = 1 (default)

Client address = 32 (default)

Password = please ask your utility provider for password

External CT ratio = ratio of the currents - if you have 250A/5A, the result is 5

External VT ratio = high voltage ratio. Only in case the counter is at medium voltage instead at 230V

5. Enter and choose Advance settings
