Fineco - EM115-MOD

Installation

1. 1Wire the RS-485 A and B terminals of the Fineco EM115-MOD to the corresponding terminals on your ModbusCloud gateway (MCG or MLP series), observing correct polarity.
2. 2Install and connect the current transformer around the phase conductor according to the EM115-MOD installation manual, ensuring the CT ratio matches the meter configuration.
3. 3Set the Modbus slave address on the EM115-MOD using the front panel buttons, and verify the baud rate is set to 9600 (factory default).
4. 4Power on the gateway and log in to the ModbusCloud platform, then assign the Fineco EM115-MOD template to the corresponding Modbus address.
5. 5Verify that live readings such as voltage, current, and power appear correctly on the dashboard before closing the distribution panel.

Things to watch for

01

I see zero values for current and power but voltage reads correctly. What is wrong?

This usually indicates a problem with the current transformer installation. Verify that the CT is properly clamped around the phase conductor and that the CT secondary wiring is connected to the correct terminals on the EM115-MOD. Also check that the CT ratio configured in the meter matches the physical CT.

02

My readings appear as very large or nonsensical numbers. What could cause this?

The EM115-MOD uses float32 (IEEE 754) registers spanning two consecutive Modbus addresses. If the register byte order or word order is mismatched, values will be decoded incorrectly. The template handles this automatically, but if you have modified register settings, verify they match the defaults.

03

Can I connect multiple EM115-MOD meters to a single gateway?

Yes. Each meter must have a unique Modbus slave address on the RS-485 bus. Use the front panel of each EM115-MOD to assign a different address. Then add a separate template instance in ModbusCloud for each address.

04

What baud rate should I use?

The default baud rate for the EM115-MOD is 9600 with 8 data bits, no parity, and 1 stop bit (8N1). Ensure the ModbusCloud gateway serial port is configured to match these settings exactly.
