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

Bit in the remarks: represents the register can only be used as bit;
Word in the remarks: represents the register can only be used as word;
Double-word in the remarks: represents that the data type of the register in configuration must be 32-bit;
Read only in the remarks represents that the register can only be read but not be written;
The names of the registers supported by different equipment model may be different, and the scopes may also be different.
