EMU Professional Modbus TCP

Installation

1. 1Connect the EMU Professional TCP/IP to your local network using an Ethernet cable and ensure it has a valid IP address.
2. 2Wire the meter to the electrical supply either directly or via current transformers (CT ratio /5 or /1A), following the EMU Professional installation manual.
3. 3Verify the Modbus TCP unit ID configured on the meter, accessible through its built-in web interface.
4. 4Connect your ModbusCloud gateway (MCG or MLP series) to the same local network as the EMU Professional meter.
5. 5Import the EMU Professional Modbus TCP template in the ModbusCloud platform and enter the meter IP address and unit ID.
6. 6Confirm that live readings for voltage, current, and energy appear on your ModbusCloud dashboard before closing the cabinet.

Things to watch for

01

Which Modbus TCP port does the EMU Professional use?

The EMU Professional TCP/IP uses the standard Modbus TCP port 502 by default. You can verify or change this in the meter's web interface.

02

Do I need to scale the register values manually?

No. The ModbusCloud template already applies the correct data types and scaling factors. Energy registers are read as uint32, power and current as int32, and voltage, power factor, and frequency as uint16.

03

Can I use this template with the RS485 version of the EMU Professional?

No. This template is designed for the TCP/IP variant only. The RS485 version uses Modbus RTU and requires a different template and wiring setup.

04

The meter shows readings on its display but nothing appears in ModbusCloud. What should I check?

Verify that the gateway and the meter are on the same subnet and that no firewall blocks port 502. Also confirm that the Modbus TCP unit ID in the template matches the one configured on the meter.
