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

Terminal of SK HMI is DB9F, and that of GE Fanuc series PLC is RJ45.
2. Software settings
Select GE Corporation in connection device service.
Select the corresponding item in connection device service according to the connected PLC model or supported protocol.
Ensure that the communication parameters in touch screen connection parameters and PLC station number are consistent with the PLC connected.
For settings of the PLC connected, refer to the technical documents of the GE Fanuc series PLC.

Note:
d represents decimal system, input range is 0-9;
o represents octal system, input range is 0-7;
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;
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.
For detailed name and scope, please consult related technical document of the connected device.
