Delta HMI and Windows 7 drivers

Nothing remains!
And finally Windows XP have a proper substitute, Windows 7.

Unfortunately, the people from Microsoft doesn’t think in HMI programmers, because the internal drivers has been changed…
Because of that we have found a solution to support those new drivers on our HMI’s.

So if you have a new Windows 7 or Windows Vista and your drivers doesn’t works, don’t worry, and just follow the next steps:

1 – Check the firmware of your HMI.
The first firmware version with the new Windows 7 drivers is V2.0170. If your HMI have a lower firmware version, please Update the HMI trough XP computer or serial port.

2 – Once you have the proper firmware, go to the system menu, and choose system setting.

3 – Then look for the MISC menu, and there you should found the option called “USBCommMode.

4 – You only need to change that USBCommMode option from 0 to 1.
USBCommMode = 0 (Windows XP)
USBCommMode = 1 (Windows Vista & Windows 7)

If do you want further information of how to update the firmware trough serial port, please download the DOP-B and W7 trouble pdf from our ftp.

We will exhibit this year at the Hannover Messe from 4-8 April, Hall 11, A49.
Just like last year we will organise a seminar to inform you about our newest products. This will take place on Wednesday 6th April from 12.30 to 17.00. We will send out a separate invitation with all the details.

We look forward to see you in Hannover.

Delta Customer FTP

Dear Readers,

I have been receiving a few complains regarding the FTP links doesn’t works.
I’d try to arrange them, but it seems that still need user and Password.
I’m sorry about that!

To solve this issue, I’ll upload all the information of this blog on the next FTP address

On the other hand, on that FTP site you will found all the new Software, Brochures, Manuals, Certificates, Pictures, etc.. of our products.

HMI – 3 PLC Communication Example

Another communication example for our blog library.
The easy one, should be do it only one HMI and one PLC. But to do it more interesting we are going to set up a Modbus ASCII network of one HMI(master) with 3 PLC’s(slaves).

To setup any system I always divide the problem in two basic parts, Hardware and Software.

Hardware (physical level):
Take a look to the pinout of all the devices to connect, in our case the PLC is easy, and for the HMI, take a look to the next image extracted from the instruction manual.

Software (Protocol):
An old trick that I learn after a couple of communication challenges is write in a post it the communication protocol that you are going to use. Basically, because you will need it so many times, and is very easy to make mistakes!!

Protocol used:
7,N,2 (Modbus, ASCII), 9600 bps

Network configuration:
HMI Address: 0 (master)
PLC1 Address: 1 (Slave)
PLC2 Address: 2 (Slave)
PLC3 Address: 3 (Slave)

Software (Computer level):
And finally, to show you how to configure the communication with the ScreenEditor and WPLSoft, I’ll ask you to download the next file, where you can file the programming examples, and some video file with the exe extension, to follow all the process.

New PLC Instructions Announcement

As a programmer, sometimes I really miss some instructions in the Delta PLC’s. Recently, I discover that the others Delta programmers miss exactly the same instructions!
Because of that, I’m glad to announce a new group of instructions/functions for the new batch of Delta PLC’s.

DVP PLC New Functions

Here related the most interesting news in my opinion
Bit control:
Finally the eagerly awaited Specific Bit control instructions!!

Mask Area Functions: Essential for Labeling applications
DZRN: Improving the Homming functions!
DVSPO: Variable Speed Pulse Output (Useful for control the speed of our motor using some analog input).
DICF: Immediately change frequency (another motion instruction thinking in typical motion applications like fly-on-the-cut).

Improving the comunication performance with the new function codes and special registers on the MODRW and PLCLink instructions.

Transform and Move Data:
New DTM instruction with several different features. I attach a temporary translation for your information, the formal translation will be released in the revision V of the manual
DTM Instruction sheet

Before you ask us how can I use that new instructions, please take a look to your PLC firmware version, and check it with the table at the end of the document.

And finally the promise of a very soon release of the new ISPSoftv1.08

Trend Graph vs. Historical Trend Graph

Some people use to doubts what Graph utility is better for his application, in this case I would like to explain the differences between Trend Graph and Historical Trend Graph.

The historical Trend graph is the typical tool to see graphically the evolution in time of some variable, for example, temperature or pressure.

The Trend graph is the tool to show graphically several values in the same graph without the time basis. This graph could be useful, for example, to show the evolution of the different temperatures in a different oven’s chain.

To make easy the implementation of these tools, please check the next examples:
