Temperature controllers: How to Return to Default settings

The ones of you who deal with Delta temperature controllers, sooner or later found on the situation to reset the Temperature controller to default values.

How to do that without using DTCOM?
Please follow the below instructions if you have a DTA or DTB
untitled
In case you have DTD4848 just change the keys [V] & [SET], for [] & [SET].

But what happen with DTC? This device have no buttons.
So If you change the Modus Address, and you do not remember what address you use… you´re in a trouble.

In this case, you have 2 options:
Or you use the LED code of the manual to guess the protocol and address
qqqqqqq

Or just follow the below instructions to take the DTC back to factory defaults:
1. Switch to “RUN, and Power on the device.

2. After 5 seconds, the device should show as below picture.

3. Switch to Stop and wait until the RUN LED is off

4. Switch to RUN and wait for the RUN LED is on again.

5. Repeat the steps (3) and (4) three times within 60 seconds, and If everything is OK, all led should switch to ON as below picture.

This feature is available starting from Firmware v1.5

In case you’re a communication guy, download the attached manual to reset to factory default all Temperature controllers using out software DTCOM.

Default reset by Communication.

PLC Password: How to protect your program?

How to protect you program?

I’m pretty sure, that If you´re a programmer is not the first time you need to protect your work.
Maybe to avoid last time changes, or maybe because is your everyday bread.
So in any of the cases, we would like to explain what password locking possibilities new ISPSoft provide to you.

1st Program Lock
In this case, you lock the computer file, to open the file you need to have the pasword, but If the program in on the PLC customer can upload without password.


full screen is recommended

2nd Subroutine Lock
Your customer can open the program with no problem, but you can lock your Function Blocks to avoid anybody steal your Know-how.


full screen is recommended

3rd PLC Lock
In this case you’re locking the PLC, to be able to upload the program from the PLC you need the password.
The password resets if you come back to factory settings, but be aware that you´re going to lose the program also!


full screen is recommended

To all of you, who have a machine in you hands with a Password, and need to extract the program for whatever reason is. I’m afraid there´s no crack or universal password.
The only think you can do is contact with your machine provider.
Or just reset to factory settings, loosing the program on the process

Successful Application: Top cleaner greenhouse deck

Another successful application from our parters in Netherlands Innomotion.

On below video new top cleaner unit for cleaning the glass roofs of greenhouses, and since last year fully equipped with delta inverters

For the cleaning brushes they use VFD-L, And to drive the car over the roof our VFD-E.
And finally to control all the sequence a simple SS2 makes all the job.

Congratulations Innomotion!

Announcement: Delta Smart Viewer

New software available on the Delta web page, and as always for free!

Delta Smart viewer is the new tool to allows us to check our PLC status using Android device, like for example our Smart phone or tablet.

TargetSetting_phone

On this recent version is only supported wifi communication, but is planned in near future to support 3G communication, being able to monitor and control our installations using our smart devices.
Up to 10 devices can be supported with the actual version.

TargetSetting

Able to monitor temperature or any other graphic value using run-chart, with a top samples number of 5000.

Furthermore, the export/import profile, makes it easy to configure other devices with same connection.

So If you have Android in your smart phone, feel free to download it from our website!
Delta Smart Viewer v1.01
In case you´re iOS user, am afraid you will need to wait
(and for windows mobile… we’ll see ;)

Warning
Delta Smart VIEWer 1.01 supports Android 2.2 ~ Android 4.2
Before downloading the software, please find and tap Settings > Security on your Android home screen and mark the Unknown sources checkbox to allow the installation of applications not from Google Play™

Successful Application: Metal bar feeder

Another successful application, and this time comes from the company Thelen Tech from Finland.

This company engineer is a big an of Delta and our step and direction solutions, and for this simple but effective solution they use 750W ASDA-B2 drive for the motion together with DVP28SV2 for the control.
And to monitor or configure speed, they add DOPB04 HMI.

Check the machine!

Originally this was planned as full automatic system, plan was there is gripper
which would push material to cutting length, then saw it, then push more… and
whole it should be fast (over 30m/min speed)

20130424_113907

The cutting length can be adjusted using manually using hand-wheel, or automatic using HMI.
There is also possibility for closed loop feed back, but in these case feedback is taken from D1336 register

20130424_114203

Also +/-10V speed command is possible, motion control just calculates difference between real and wanted position and turns it PWM (or voltage).
This pretty nice arrangement for relative (like MPG) and absolute positioning using at the same time.

Diagnostics Screen, very useful for the designer.

Thank you very much Thelen Tech to share this new machine with us!
Keep impressing us like that!

Successful Application: 11 Axis Cutting / profiling machine

Another successful application from our Netherlands distributor Innomotion.

This time is a Woodcutting / Profiling machine with 11 axis control!

Kast

As you can see on the picture our partners use 7 VFD-E drives for transportation and high speed spindle, and 4 servodrives ASDA-A2 400W for the cutting/profiling.
Everything controlled by central CPU with Master CANopen module (DVPCOPM-SL).

stootborden1

Via the PC Cad drawings are imported to the Machine and machine settings are executed. The PLC is controlling all the I/O and servo’s for the motion.
In this machine the wooden boards for the stairs are cut to length , width and angle on front and end of the board. The PC software is written in Labview.

I hope you like it!
And with some luck, you can use it as inspiration for your next project!

PLC RS232/RS485 send frames

This trick is for the very special application when we want to communicate with unknown device trough serial communication using our Delta PLC.

If the slave is Delta, we can always use PLC Link.
But what happens when the slave is not delta?

In this case we have 2 options.
First use our DVP12SCM-SL module with 2 extension ports to help us on the frame configuration.
Second the solution we’ll show in this post.
Basically all our PLC have by default 2 communication ports RS485 (below) and RS232 (in front).
And some have a 3rd RS485 port, usable also to send single frames to other slaves.

111111
COM1 – RED
COM2 – GREEN
COM3 – BLUE

Once you got the port selected, then you need to set up the port configuration.
Use the below table, or our WPLSoft wizard if you are still WPLSoft users.

untitled

On our examples below we used D1036=87H what means:
- Data Lenght 8
- Parity Even
- Stop Bits 1Bit
- Baudrate 9600 bps

Use this table to create the Hexadecimal number, or use WPLSoft wizard
untitled1

Before COM port configuation, we´ll going to use RS instruction.

untitled23

Basically RS instruction is to configure where I’m going to save the data to be sent and received.
But to trigger the frame, you will need to trigger special mark.

COM1:M1312
COM2 M1122
COM3 M1316

Once this mark is high, the PLC send the frame configurated in the RS instruction.
If on the other way around, our PLC is waiting for some transmision, then we´ll need to wait until the data is recieved.
The mark that will tell us when the data is available is:

COM1:M1313
COM2 M1124
COM3 M1317

And you will find the info on D1070 – D1085 special registers range.

To help you on this special application, download the following Send Frame trough RS232 and Send Frame trough RS485.
We also add some section of the manual with the special marks to be aware when you play with this instruction.

Send Frame Help

Recomendation!
When you work with comunications, is always advised to have some sniffer, to see what happens on the network. In RS485 case, I recommend to have IFD6500 and any freeware Modbus sniffer.
And remeber, with comunications…always patience.
Good luck.
