Announcement: Phase out DOP-B07Sxx

Due the new DOP-B07S415 / DOP-B07E415 HMI model, we decide to phase out the DOP-B07S200 / DOP-B07S201 / DOP-B07S211 models.

The pannel cutout of this new HMI is exactly the same of the older ones.
And of course inside those new HMI you can found many improvements.

See the following ones:

The most sharp, probably may see another important difference.
In this new Delta HMI we decide to discard auxiliary Buttons.
In fact this is a company policy decision, because none of the future Delta HMI will have buttons any more.

Finally, I would like to share with you what is the new Delta HMI scene, compiling all the phasing out and new product launch on the next table

HMI Getting Started

Here it is!
Again thinking in the begginers (and in this case not only them), let me share with you all our kit HMI Getting Started.
For the ones who uses PLC Getting started, and for the other too

HMI used to be more intuitive and user friendly than the PLC, but If you are trying to accomplish a complete program with reciepe, graph pictures etc.. you need some knowledge.
So our intention is give you some tutorials and examples and all the necessary tools to made your learning time as short as possible.

In this HMI getting started you will find:
1. eRemote / eServer Tutorials
2. HMI communication Examples with Delta devices
3. Manuals for DOPA and DOPB
4. Program examples for many features (graph, password, History, Event, Alarm, etc…)

Don’t hesitate to share with everybody.

HMI Getting Started

Announcement: New products DVP02LC-SL and DVPSCM12-SL

The new S series models upgrade, give us the capability to start to use high speed left bus more often.
In the past we only have DVP-28SV, but now we could connect our high speed modules in two new CPU’s DVP-12SA2 and DVP-20SX2.
Because of that, our Delta engineers develop new high speed modules to make our life easy.
The first one is DVP02LC-SL.

DVP02LC-SL is device designed for two functions: Tension control applications and Weight applications.
It provides 24-bit resolution applicable for 4-wire or 6-wire load cells with various eigenvalues.

Below you can download the official product announcement with the features of the device. Furthermore, we add some real field application to understand the functionality of this device.

This device is already available

The other important launch in relation with High speed left side modules, is this 2 multi-use Serial communication ports.
Basically are 2 serial expansion RS485/RS422 ports with the capability to change the frame construction. This allows us to communicate with every kind of device with serial communication.

The principal assets are:
1. Can be used as extra port to monitor and program the MPU.
2. Can add to the PLC up to 16 ports, these means that our 32 node limitation of RS485 can reach now up to 512 devices.
3. Strongly noise immunization with 120 ohm terminal resistor embedded.
4. User-defined communication (UD Link) provides flexible communication protocol interface. It’s made
DVPSCM12-SL can connect to all kinds of serial communication device.

PLC Link (PLC to VFD)

PLC-Link is not only a tool to exchange data between PLC’s.
With PLC-link you can also share memory space with a servo, inverter, temperature controller, etc…
In this case I would show you the procedure to do it with VFD-E series drive.

The advantage of this method agains the “sending frames one” is that you don’t need to program and trigger one frame for every value read or write to the slave.
With this method, you only have to configurate the communication, and you will have any Slave value in your master buffers.
follow the next steps:

1. Hardware
use exactly the same advices as the PLC-VFD communication post.

2. Decide the protocol to be used.
And write it on a post it in front of you. In this case we use protocol Modbus ASCII, 9600 baud,7,Even,1

3. Inverter configuration (almost same as PLC-VFD communcation post)
The important think on this step is get ready the inverter to receive orders from RS485 interface, so depending the inverter the values are going to be different. In this example I use VFD-E.
Check the parameters If you are going to use another inverter.

2.00 = 3
Source of First Master Frequency Command
3: RS-485 (RJ-45) communication

2.01 = 3
Source of First Operation Command
3: RS-485 (RJ-45) communication. Keypad STOP/RESET enabled.

9.00 = 2
Communication Address
in my example 2

9.01 = 1
Transmission Speed
3: Baud rate 9600bps

9.04 = 1
Communication Protocol
0: 7,E,1 (Modbus, ASCII)

4. PLC Software
In this case I recommend to have the manual opened, because basically is a matter to configure the PLC-Link special registers properly.

D1399:ID address of the first slave
D1434:Number of consecutive registers to be Read (by the master)
D1355:First register direction of the slave to be Read (H2102 = Frequency command)
D1450: Number of consecutive registers to be Write (by the master)
D1415: First register direction of the slave to be Write (H2001 = Frequency command)
D1480:Readed values Master Buffer (Slave 1)
D1496:Writed values Master Buffer (Slave 1)

To find what register I need to edit in each case, look in the manual for any of those registers, and look for the proper one.

And Check the following program and test it.

I’m pretty sure that system will save you a lot of time and efforts.
