What is Modbus RTU protocol for industrial instruments? How to configure Modbus RTU communication for electromagnetic flowmeters?

Modbus RTU protocol is a widely adopted serial communication standard in industrial automation, utilizing binary encoding and CRC error checking for reliable data transmission. LGF electromagnetic flowmeters and EC32/EC60 RTU series fully support standard Modbus RTU communication.

• Communication Parameters: Typically configured with 9600 baud rate, 8 data bits, 1 stop bit, and optional parity checking
• Device Addressing: Each device requires a unique slave address (1-247) to prevent communication conflicts
• Function Code Support: 03 Read Holding Registers, 04 Read Input Registers, 06 Write Single Register, 16 Write Multiple Registers
• Register Mapping: Instantaneous flow, totalizer, temperature, and pressure parameters correspond to specific register addresses

Ecolor Technology products ship with default address 1 and 9600 baud rate. Users can modify communication parameters via configuration software or handheld terminals for seamless integration with PLC and DCS systems.
