MODBUS TCP communication between C2000 and AH500 in speed mode

Modbus RTU is a famous layer 2 fieldbus protocol used in wide range of applications since the mid 80’s and it has its encapsulation in a Ethernet frame, on TCP/IP protocol of layer 4 – 3 of OSI model. It can be used on Ethernet networks though a logic IP address, Modbus TCP uses the same function codes of RTU. The main advantage is that it is faster and can be used to send or receive data through any Ethernet device such as switches and routers in different topologies like star, tree or other line topologies using TCP/UDP/IP protocols in Layer 3-4. It can be installed in Standard 10, 100 or 1000 Mbit/s Ethernet technology based on copper cables, fiber optics or wireless standards can be used. Number of stations is almost infinite and it can go up to a speed of 1.5 Kbyte per telegram frame.

Homing and Positioning with C2000 with S7 1500 / 1200 via Profibus-DP

Positioning is one of the main applications of drive technologies and motion control and  the necessity of positioning in industrial applications is quite wide and there are many applications where positioning could be applied. Some of these applications are a process machine valve, a conveyor, the thread of a ball-screw, a lifter, a drilling machine pattern or a driving cart through an assembly line. Precise positioning (tenths of millimeters for CNC for example) takes into account many other factors and are driven by Servo-controllers like the Delta ASD family servo-drives. However, the  C2000 can be used for a variety of positioning functions with all robustness of a power drive for non-precise application where millimeters or less are not a problem. In this application we are going to learn how to set a drive system with C2000 for positioning, and how to transfer a position command using Profibus-DP from a S7-Siemens PLC with  TIA PORTAL.

C2000 as a Master for Modbus RTU for P2p using TPEditor for display

MODBUS RTU is a layer 2 network protocol created in the end of the 70’s with the necessity of a fieldbus protocol in industry to transmit and receive data in a simple way through the many devices of a network, in mind. MODBUS RTU uses RS-485 electrical standards and works on a Master-Slave setup, where a master writes and reads data into the registers of the slaves in the network. It has become the default protocol in many industry devices like PLCs, drives, sensors and it is highly used nowadays.

The Delta C2000 also uses MODBUS RTU as a built-in communication protocol. In this application note we are going to learn how to set up a Master – slave configuration, write, read and program the internal PLC with ISPsoft to work on a peer-to-peer (P2P) application with 2 motors, one used as a master and other as a slave. P2P is used when we want both motors to run at the same speed together in an application and monitor their current, its typical use can be applied to pumps, fans, conveyors, rollers. It can be also taken as an alternative for the analog input/output of the drive, when we need more than just 2 measurements. Delta C2000 also permits to create a small Text panel customized display with TPEditor, which we will follow at the end of the chapters.

Easy control of Delta VFD drives

This week we would like to show you two new function blocks (FB) that we have developed to make even easier to use Delta Industrial Automation products.

Usually we need to control several AC drives from a single Master PLC and Modbus communication is a cheap and helpful way to get it.

In order to reduce programming and commissioning time we have developed two FB:

  • COM2_VFDLINK: Configures the communication parameters (baudrate, number of bits, parity,…) that all the nodes on the network have to share and informs about the communication state of each node.
  • DELTA_VFD: Controls each one of the slaves VFD, we can Start/Stop, Forward/Reverse, frequency command and reset faults. On the other side, the FB informs us about the status of the drive, alarm code, output frequency and output current.

Below you’ll find the FB library ready to be imported in your ISPSoft and a little pdf explaining the I/O of each FB, enjoy it!




How to connect C/CP2000 to S7 1500/1200 using Profibus-DP

PROFIBUS DP is a widely used layer 2 industrial network protocol patented by Siemens and a default protocol in many Siemens automation products. In this application note we will learn how to exchange data between Delta C2000 drives and S7 1500 PLC through Profibus-DP Fieldbus. In the first part, the  hardware setup of it will be covered including GSD installation.

After that, we will check how to communicate through PZD (cyclic data), memory addresses, words and bits on both sides of communication with practical examples of C2000 Delta drives.

The example was made with S7 1500 and TIA portal with Delta C2000, but it can surely also be used for the S7 1200 and CP2000.

Succsessful Application: Galvanizing production line on metal industry

Another Delta successful application!


This time, the problem comes because of the big number of drives needed for the application.
Up to 68 Slaves to be controlled by a PLC, and even in Modus the theoretic limit is 128 nodes, the ones who are really in the field should know than more than 32 nodes means big troubles.

According to this, we recommend to our customer to use CANOpen in two different CANOpen Networks of 34 slaves each.
See the below picture with the network configuration


Just let you know that it wasn’t easy, but is working, thanks for the great technicians of our Turkish distributor FastLTD.

Feel free to download the presentation with full explanation of the application.
CanOpen_ Galvanizing production line on metal industry

Succesful Application: Electric Concrete Truck

This is a new application for our Netherlands distributor Innomotion.
The idea is to make a concrete truck more economic and silent.

Normally the drum is turned with diesel power (hydraulics) from the truck.
Now the drum is loaded at the factory on electric power (cable) and on the road a small generator is supplying just enough power for slow turning and unloading of the truck.

It will save fuel but most of all were possible the truck can unload on the cable so in the innercities there is less pollution on the building site and less noise.

Inside the big cabinet there is a C2000 45KW delta PLC and HMI.
Nice eco-project Innomotion!
Dank u wel

Successful Aplication: C2000 for Injection Molding Machine

Injection Molding machines is a quite common application, because of that, Delta develop several solution depending on the different type of injection moldign machine.


In frirst place, we develop specific solution for this application called HES
This system provides precise pressure and flow controls, with our Delta key point in power: The energy savings.
In this moments, this product is under field test in Asia, and really soon on the rest of the world!
But If you want to take a look over our technology, check the below presentation

HES Techology

But for standard systems we got another solution.
Probably many of you already hear about our new C2000 Delta Inverter series, and possibly many of you already work with it in some application.
So this is one of the multiple ways to squeeze the capabilities of this versatile product.

Hybrid System based on C2000

The keypoint in this system is use the internal PLC and the PG card (encoder feedback) of C2000 to create a standalone control system able to adjust itself without any extra controller.
On the below links you will find the parameter configuration and PLC program to beable to test by yourselves.

CANOpen Communication: DVPCOPM-SL with VFD-EC

Why Can Open?

Modbus is strong an with a long and successful story of applications, but when interpolation is needed, you should need something else..
Is strong, easy to use, and more important fully compatible with many different brand devices on the market.

Because of that we want to start a new Can Open Category with simple applications, easy to work on.
In the near future we will keep adding Can Open examples with all our new compatible Can Open devices (ASDA-A2, C2000, etc…) but for start our cost effective CANOpen drive VFD-EC will work.
Let´s start with the Hardware.

Hardware Configuration:

1. DVP-SX2 + DVPCOPM-SL (CANOpen Master)
2. VFD-EC (CANOpen Embedded Slave)
3. TAP-CN03 (CANOpen Splitter with terminal resistor)
4. TAP-CB03 (CANOpen Cable)

Be aware on the following advices:
– Use CANOpen wirings, Ethernet cables have the same pin-out, and they will work on short distances, but it can give you problems due they don´t have same internal impedance.
– Remember to turn on the terminal resistor switch of TAP-CN03! If you don´t want to use it, remember to put 120 Ohm terminal resistor.
– No need to supply V+ and V- connections for short distances, for long ones is recommended.

So at last, you may have something similar to this:

VFD-EC Configuration:

P0.02 -> 9 Reset fatory default values

P2.00 -> 5 CANopen of First master frequency command
P2.01 -> 5 CANOpen of forst operation command
P4.08 -> 23 multi-function input terminal (MI6) as Emergency STOP (link MI6 and DCM to work)
P9.20 -> 2 CANopen Station Address
P9.21 -> 0 CANOpen Baudrate 1Mbps
P9.24 -> 1 Adapt DS402 protocol

CANOpen Builder Configuration:

Full screen recommended

As you can see in the video, once you link on the EDS files the inverter parameters with the PLC registers, you just have to work with them as local registers in the PLC.
The PDO frames are going to be sended automatically in a continuous matter, so every change will be automatically updated in the other device.

HMI and PLC Program:
And after that, you only need to download the PLC and HMI programs.
You will find it in the following link.
The HMI and PLC are connected trough RS232 (DVPACAB2030), but you can change it with no problem.
