TaiAn device driver
|
The device driver is used for SK HMI to read and write the data or state of TaiAn TP03 series PLC register. The serial communication connection is established through the serial port on the touch screen and the serial port of TaiAn TP03 series PLC, so as to operate TaiAn TP03 series PLC. Prior to use of the driver, one shall carefully read the chapter and related technical specifications of TaiAn TP03 series PLC.
