READING AND WRITING I/O DATA VIA MODBUS-RTU COMMUNICATION
The device is intended to be used with PC recorder software (model: PC Recorder), but it is also possible to read and write I/O data via Modbus-RTU communication through USB (virtual COM port).
When the PC and the device are connected with a USB cable, a virtual COM port is created on the PC.
The node address is fixed at 1, and communication is possible with any settings for baud rate, parity, and stop bit.
