คู่มือและคำแนะนำการใช้งาน SONBUS

ซนบัส (Shanghai Sonbest Industrial Co., Ltd) is a leading manufacturer of professional sensing equipment and industrial instruments. Operating brands such as ซันเบสท์, เคแอลเอชเอ, และ ทรานบอล, the company specializes in solutions for agricultural automation and intelligent industrial control.

The SONBUS product line includes high-precision sensors for measuring temperature, humidity, soil conductivity, soil moisture, and various gas concentrations. Designed for system integrators, these devices typically support standard protocols like RS485 MODBUS-RTU, 4-20mA, and 0-5V/10V analog outputs, ensuring seamless compatibility with PLCs, DCS, and other monitoring systems.

• What communication protocols do SONBUS sensors typically use?

  Most SONBUS sensors utilize the standard RS485 MODBUS-RTU protocol. Some models also offer analog outputs (4-20mA, 0-5V, 0-10V) or wireless options like LoRa, Zigbee, and WiFi.

• How do I change the device address on a SONBUS RS485 sensor?

  You can change the device address by writing to the specific register (often register 0x66) using the RS485 Modbus write command (function code 0x06). Refer to the specific product manual for the exact register map and command structure.

• What is the default baud rate for SONBUS Modbus devices?

  The default baud rate is typically 9600 bps with 8 data bits, no parity, and 1 stop bit (9600, 8, N, 1). This can usually be modified via software commands.

• Where can I find the software to configure SONBUS sensors?

  Configuration usually requires a standard serial port debugging tool or Modbus poll software connected via a USB-to-RS485 converter. SONBUS may also provide specific utility software for their devices on their official webเว็บไซต์.
