How to transfer a HMI and PLC program from a USB Flash Drive
This application note includes three parts:
Part 1) Steps on how to save the HMI program in .znv file format and the PLC program in .zld file format
in USB Flash drivePart 2) Steps on how to configure the settings in USB Auto-Run Software Tool for the HMI and the PLC
buttons
Part 3) The last part of this document shows exactly how to go about programming the HMI and PLC
from the USB drive, with screen captures of what you see as you go through the process.
In this example, the HMI IP address is 192.168.1.6 and the PLC IP address is 192.168.1.5.
Below are the steps on how to save the HMI program in .znv file format in USB Flash Drive1)
2)
3)

E:\HGDATA01\NVDATA
4) Click OK to close the dialog box.
Next, Click on “Button 2 Not Registered” to repeat the step 2 for the PLC program.
5) In Command Settings, enter Title, Select “Download PLC Program” in Command, enter Path,
Select “Ethernet” and enter PLC IP address. Click OK to close the dialog box.

6) Click “File” and select “Save As”. Select E:\ drive and click Save. It will save the file with thename hgauto.ini

Please double check to see if you have all the necessary files in the USB flash drive. You shouldhave .ZNV file, .ZLD file, and hgauto.ini file. The .ZNV file usually can be found in HGDATA01  NVDATAfolder.

Lastly, this document shows exactly how to go about programming the brandnew HMI and PLC from the USB drive, with screen captures of what you see as
you go through the process.
When you power up the brand new HMI, the System Mode Top Page will be displayed as below.

If the brand new PLC is used, please make sure the battery is inserted into the PLC.

And also, turn the digit switch to a position 1 as below.

1) Unplug USB memory stick from your computer and plug it into the HMI onto USB2 slot.

2) A window will pop up with a Data Transfer Mode follow by another window Confirmation thathas “Download Project” buttons on it.

3) Download the HMI program first by pressing “Load ZNV” button. When ZNV button is pressed,
the HMI project in the USB memory stick will be started transferring into the HMI.

4) When the transfer is completed, the screenshot below will pop up. Press ACK to close the dialogbox.

5) Next, press “Load Zld” to download the PLC program from the USB stick to the PLC via HMI.

6) The “PLC Program Transfer” message will be displayed.

7) When it’s complete, below message will be displayed as “The function completed”. Press ACK.
