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

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;
Bit in the remarks: represents the register can only be used as 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.
