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.

DVP04TC-S/DVP04PT-S & DTE Channel setup

For DVP04TC-s/ DVP04PT-s and DTE its is possible to configure the input channels for different sensor types and also disable the unused channels. This will prevent flashing error LED when no other errors are present.

  • For DVP04TC-s and DVP04PT-S we use Control Register 1 (CR#1):

Example 1: For DVP04TC-S set CH1 for J-type sensor, CH2 K-type sensor, CH3 T-type sensor and disable CH4.

CH1 = (b2-b0) = (0, 0, 0) for J-type

CH2 = (b5-b3) = (0, 0, 1) for K-type

CH3 = (b6-b8) = (1, 0, 0) for T-type

CH4 = (b11-b9) = (1, 1, 1) to disable channel



Example 2: For DVP04PT-S set CH1 for PT100 sensor, CH2 NI100 sensor and disable CH3-4.

CH1 = (b3-b0) = (0, 0, 0, 0) for PT100

CH2 = (b7-b4) = (0, 0, 0, 1) for NI100

CH3 = (b11-b8) = (1, 1, 1, 1) to disable channel

CH4 = (b15-b12) = (1, 1, 1, 1) to disable channel




  • For DTE we use Function Address 10F6H :

Example 3: For DTE set CH1 – CH4 Enable, CH5 -CH7 Disable & CH8 Enable:

CH1(b0) = (0) Enable

CH2(b1) = (0) Enable

CH3(b2) = (0) Enable

CH4(b3) = (0) Enable

CH5(b4) = (1) Disable

CH6(b5) = (1) Disable

CH7(b6) = (1) Disable

CH8(b7) = (0) Enable

Write data 01110000 0r 70H to Function Address 10F6H





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.

You can also download the C2000 fine tuning for this application:

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!




Data exchange between the Delta DVP12-SE PLC and Other PLC via Ethernet

DVP12-SE PLC can be configured to exchange data between other PLCs via Ethernet(modbus TCP/IP) by using DCISoft  Software. DCISoft  Software is an integrated configuration tool of Delta network modules for WINDOWS operation system. Below is how to configure DVP12-SE for Data Exchange with other PLCs.

2. Auto Search

After setting the communication type and communication parameter, then push the “Auto Search” button to search  for the DVP12-SE in the DCISoft for configuration.


3. Setup Overview : after the step above, the interface below will appear. Double-click on the DVP12-SE module icon contained in the interface  below to enter the setup overview page.


4. Overview

After the step above, the interface below will appear which contains several tabs in the tool bar. The first tab is the overview tab, this tab shows the current basic status of the DVP12-SE PLC module. I will further talk about the Basic and the Data Exchange tabs used for the configuration of the DVP12-SE PLC.


5. Basic settings 

Push the basic tab, the interface below for setting the network parameter will appear.


5.1 Module name:  There can be many DVP12-SE on the network. Thus, you can set up a module name for each module to identify the module when you need to use them.

5.2 Network setup: In the IP configuration field, you can Enable DHCP (DHCP: is Automatically updated by the server. There has to be a server in the LAN) or static IP. (Static IP: Is Preset or manually modified by the user).  if you choose Static IP, manually modified  the; IP addressSubnet mask (Netmask ) and the Gateway IP.

6. Data Exchange 

Click the data exchange tab, the interface below will appear. The Data Exchange is used for configuring exchange of data between PLC via network. A Delta Ethernet master can read/write data from/into a slave.

If a device which is not a Delta PLC is connected, users can use the  hexadecimal four-digit MODBUS address of the device for data exchange.

Data exchange.PNG

6.1. Enable  data Exchange:
Users can enable or disable a data exchange. After a data exchange is enabled, the data will
be exchanged

6.2 .Enable Condition:
In the enable condition field,you can select Always Enable,Program Control or PLC Run. If Always Enable is selected,DVP12-SE will execute data exchange continuously until the setting in DCISoft is changed.
If Program Control is selected, DVP12-SE will execute data exchange according to the
program setting. If PLC Run is selected, DVP12-SE will execute data exchange when the DVP12-SE Run Mode switch is activated

6.3. Slave ID, IP Address and Enable (Station Address-IP Address:)
You have to type in the IP address of the slaves. for example, If the IP address of a slave is, and the station number of the slave is 1, you can type 1 in the first Slave ID cell, select the box in the first Enable cell, and type  in the first IP Address cell. You have to enable and include the IP addresses of the other  PLC that will be  slaves

6.4. Master Device, Slave Device, and Quantity:

below is a brief information about the function of Master Device, Slave Device, and Quantity in data exchange dialog box of DCISoft.

In the Master Device, Slave Device cell,  if the the slaves device is a Delta PLC, enter the starting D register that you will use for data exchange.

If the slave is a third party device(not a delta PLC), enter the an hexadecimal four-digit MODBUS address that the device will use for data exchange. see below the meaning of the arrow signs in the master device and slave device column of  data exchange page in DCISoft.

Reading (): Initial reception register in a masterInitial transmission register in a slave

Writing (): Initial transmission register in a master Initial reception register in a slave

6.5. Quantity: A slave station can send 100 pieces of data at most and receive 100 pieces of data at most  Simultaneously

See explanation below on how the Quantity  field of data exchange works.


From the figure above, with the quantity specified as 100, see explanation below what the specified D registers does.

writing data from the slave side and receiving data at the master side ( )

Looking at the first row of the Master Device and Slave Device column as contained in the figure above, The master will use D register ; D0, D1……….up to D99 (that is possible 100 pieces of different data base on the “100” Quantity Specified in DCISoft) to receive the data written by  D99, D100…..up to D199 of the slave  simultaneously. (that is possible 100 pieces of different data base on the “100 ” Quantity Specified in DCISoft)

writing data from the master side and receiving data at the slave side ()

Looking at the second row of the  Master Device and Slave Device column as contained in the figure above, The master can write data to the slave D register using D200, D201……up to D300 and the slave can read this data using D300, D301…D400.

From the configuration above, I can send and receive up to 100 pieces of different data by enabling data exchange and specifying a quantity of 100.

7. Reconstruction


To save your configuration to your PC desktop or USB stick, push the new button as show above and save the DCISoft file


Look at the video below to see how I send and receive data between two DVP12-SE using the configuration that I explained earlier above, I use one DVP12-SE PLC as a master and the other DVP12-SE PLC as a slave for data exchange.
