Modbus ASCII/RTU Slave Board
This Modbus solution from Renesas is widely used in the automation industry
Renesas’ winning combination Modbus is widely used in the field of factory automation and plant automation because its specifications are open to the public, free to use, and relatively easy to implement. Therefore, Modbus is the most common serial communication protocol for connecting industrial equipment.
Modbus is based on serial communication and has two transmission modes, Modbus ASCII and Modbus RTU. The physical layer often uses the RS-485 standard. By combining the RL78 microcontroller (MCU) with sample programs and RS-485 transceiver products, users can easily implement slave devices that communicate using Modbus ASCII or Modbus RTU. The RL78 microcontroller has excellent low power operation, making it ideal for simple functions such as low power operation, I/O control, and temperature and humidity measurement.
- Modbus ASCII/RTU enables 1: N connection and communication with a maximum transmission distance of 500 m by using RS-485 for the physical layer
- Modbus can manage the environment in the factory by acquiring the illuminance, air quality, and temperature and humidity information to control the equipment and air vents
