How to connect multiple sensor devices via RS485 interface with EC32/EC60 series RTU?
Guide on connecting multiple devices via RS485 interface with EC32/EC60 RTU
EC32/EC60 series RTU remote terminals are equipped with standard RS485 communication interface supporting Modbus RTU protocol, capable of connecting up to 32 sensor devices simultaneously. When connecting via RS485 bus, each device must be assigned a unique slave address.
Key connection configuration points:
- Use twisted pair or shielded cable for RS485 wiring
- Add 120Ω termination resistors at both ends of the bus
- Set appropriate baud rate (1200-115200bps) and data format
- Configure device polling interval and timeout parameters
- Support various devices like electromagnetic flowmeters, pressure transmitters, temperature sensors
The RTU data collector automatically polls each device, with collected data uploaded to cloud platforms or SCADA systems via 4G network. Works optimally when combined with Ecolor's LGF series electromagnetic flowmeters.
