HMI

Download/Upload PLC program directly from/to USB through HMI

When users don’t have easy access to a laptop nor PC nearby the installation or the machine, is difficult to face the task of making some modification or backups by downloading/uploading the PLC program.

For this purpose, there’s a way to download/upload the PLC program directly from/to a USB memory stick through the DOP HMI.

Let’s explain the procedure in few steps assuming the case of downloading program from USB to PLC:

1. Copy the PLC program (.DVP) into an USB memory stick

2. Insert the memory stick into the USB port of the HMI

3. Enter the system menu of the HMI by pressing the “SYSTEM” button (at the rear side of the HMI) for few seconds. You will hear a “bip” sound

4. Enter the “Up/Download” sub menu

5. Select “HMI <->PLC” transfer mode by navigating through the  “LEFT” and “RIGHT” buttons at the bottom

6. Click “USB:\” on the left part of the screen and select the PLC program file you want do download

7. On the right part of the screen, select the COM port that is connected to the PLC (COM1 in this example)

Important note: The file name in the PLC to be uploaded or downloaded using this function must be DVP-xxx.dvp (xxx must be a number between 000 and 999.)

Delta Electronics participated in Middle East Electricity show in Dubai

Delta Electronics has showed its products and solutions in the MEE exhibition held in Dubai (1-3 March).

Various products were demonstrated in the booth, including PLCs, HMIs, Drives, Servo and Delta Multi-Pump Solution (DMPS).

Visitors from all around the middle east were present, good connections were made and costumers showed lots of interest in our products.

Due to the fact that oil prices are going down, and most of the projects in the Gulf area are oil and gas related projects, lots of costumers moved their attention to Delta as an economic alternative to other brands.

Some pictures from the show:

See you soon in Hannover Messe, April.

HMI – PLC Real Time Clock Setting

Real Time Clock Sync

Since real time clock synchronization between HMI and PLC is a normal requirement for most application, we’d like to show you the updating function of real time clock provided by DOPSoft.

You can refer to the below technical document for the complete explanation on how to set real time clock synchronization.

I hope it will be useful for you all !

Good luck !

HMI new Instruction: Grid Box

Do you ever work with huge recipe?
If you did, you will know how uncomfortable is sometimes.

So in this case our programmers trying to make our life easier, they develop the Grid Box tool.
As you can see in the video below makes the Recipe edit much more simple.

But because to manage this tool is not easy, here below you can find the video example together with it’s technical announcement.

I hope it will be useful for you all!

HMI – HMI – PLC – PLC Communication Example (Multidrop)

Another useful Ethernet application with our new HMI´s is the multi-drop connection.

As you can see in the picture configuration, Multi-drop means have 2 mirror HMI´s where can be used and all the actions in one HMI, will be mirrored on the other one.
To do this, we need as always one master and one slave, or with the proper words, one Host and one Client.

Where our customers use Multidrop? The typical applicaion use to be a huge machine with several control points, printing machine, Parking, etc…

If you are interested follow the tutorial.

1. HMI Host configuration

2. Confiurate IP addresss of Host and client on the same Range

3. HMI Client configuration

You can download the full tutorial and some example on the following link.

And as always don´t hesitate to let us know your commentaries
