Nanda device driver

Nanda

The device driver is used for SK HMI to read and write the data or state of Nanda NA-200/400 series PLC register. The serial communication connection is established through the serial port on the touch screen and the serial port of Nanda NA-200/400 series PLC, so as to operate Nanda NA-200/400 series PLC. Prior to use of the driver, one shall carefully read related technical specifications of the chapter and Nanda NA-200/400 series PLC.

How to establish connection with Nanda NA-200/400 series PLC

1. Hardware connection

Connecting cable:

RS232

SK HMI COM1/COM2		Nanda NA-200/400
2	RX	3	TX
3	TX	2	RX
5	GND	5	GND

Terminal of HMI is DB9F, and that of Nanda NA-200/400 series PLC is DB9M.

2. Software settings

Select Nanda Auto Technology 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 Nanda NA-200/400 series PLC.

Note:

d represents decimal system, input range is 0-9;

Word in the remarks: represents the register can only be used as word;

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.

For detailed name and scope, please consult related technical document of the connected device
