AIBUS device driver
The device driver is used for SK series HMI to read and write the data or state of AIBUS device via AIBUS protocols. The serial communication connection is established through the serial port of the HMI and the serial port of AIBUS device, so as to operate AIBUS device. Prior to use of the driver, please carefully read this chapter and the related technical specifications of the AIBUS device.
