The Sunlight GroupEMS communicates with the FD‑EC amplifier via Ethernet (Modbus TCP).
Connect the Ethernet cable from the amplifier unit to any free controller network port or network switch on the same LAN.
You MUST give each devicea unique address on the RS485 bus. Check the device manual for instructions.
Use lower addresses first (1, 2, ...) because the Sunlight GroupEMS will find them faster!
For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The Sunlight GroupEMS will scan those first.
IP address – the address of the FD‑EC amplifier (for example: 192.168.1.120).
TCP port – 502 (default).
Slave address – 1 (fixed value for this model).
Save to return to the device list.
Tip
Tip
To find or set the amplifier’s IP address, use the MP‑F Monitor software or the setup menu on the amplifier display.
Keep your controller and the FD‑EC on the same local subnet.
Open the Keyence Flowmeter device settings screen.
Set the number of connected flow sensors (for example, 1 or 2).
For each sensor, enable or disable data channels such as:
Flow rate (L/min)
Total water usage (L)
Temperature (°C)
Heat power (kW)
Energy consumption (kWh)
Save your changes and press Apply Configuration.
Warning
Warning
Avoid polling the same FD‑EC unit from multiple controllers or software tools simultaneously.
Only one active Modbus‑TCP connection is supported at a time.
