E+E Elektronik EE074 - Temperature Probe with Modbus RTU

Installation

1. 1Wire the EE074 probe to the RS-485 terminal (A, B, GND) of your ModbusCloud gateway (MCG or MLP series).
2. 2Set the EE074 slave address using the probe's configuration method and ensure it is unique on the RS-485 bus.
3. 3Configure the gateway serial port to 9600 baud, odd parity (1 stop bit) to match the EE074 default settings.
4. 4Import the E+E Elektronik EE074 template from the ModbusCloud template library and assign it to the correct gateway port.
5. 5Verify that temperature values in Celsius, Fahrenheit and Kelvin appear on the ModbusCloud dashboard after the first poll cycle.

Things to watch for

01

I see zero or incorrect temperature values on the dashboard. What should I check?

Confirm that the gateway serial port is set to 9600 baud with odd parity. Also verify the float32 byte and word order matches the EE074 output. Swapping word order is the most common cause of garbled readings.

02

Can I connect multiple EE074 probes on one RS-485 bus?

Yes. Assign a unique Modbus slave address to each probe and add a separate template instance per address in ModbusCloud.

03

Which register addresses does this template use?

The template reads holding registers 1002 (°C), 1004 (°F) and 1008 (K). Each value is a float32 occupying two consecutive registers.

04

Do I need to enable Modbus on the EE074 before connecting?

The EE074 ships with Modbus RTU enabled by default. If communication fails, verify that the slave address and baud rate have not been changed from factory settings.
