Mitsubishi device driver
The device driver is used for SK HMI to read and write the data or state of Melsec FXxn/Q00J/C24N series PLC register. The serial communication connection is established through the serial port on the touch screen and the serial port of Melsec FXxn/Q00J/C24N series PLC, so as to operate Melsec FXxn/Q00J/C24N series PLC. Prior to use of the driver, one shall carefully read the related technical specifications of the chapter and Melsec FXxn/Q00J/C24N series PLC.
How to establish connection with Melsec FXxn/Q00J/Q00U/C24N series PLC

2. Software settings
Select MITSUBISHI 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 Melsec FXxn/Q00J/C24N series PLC.
