FTP Server enables users to download alarms, historical information and recipes from USB Disk or SD storage device to PC. Also possible to upload files from PC to USB or SD storage Device enabling the user to effect changes to alarms, historical information recipes and PLC program.

Supported HMI:

  • Network type

Supported connection methods:

  • Software for file transmission ( for example FileZilla )
  • Windows explorer
  • DOS command line

Connection Limit:

  • Maximum 3 on-line clients at the same time
  • FTP Server will automatically disconnected if unused for 90 seconds

Logon Methods:

  • Anonymous logon:
    • Users cannot add directory, upload/download files, delete files or change file names.
  • Account logon:
    • Users can add directory, upload/download files, delete files or change file names.

Example: Customer would like to upload existing recipe file to PC, make changes and then download to HMI. In this example we will use file transmission software FileZilla available here:

Solution: Please see short video below where we run trough the setup process and run the application. Also available in the attachments are the HMI .dps file and documentation for FTP setup.

Download/Upload PLC program directly from/to USB through HMI

When users don’t have easy access to a laptop nor PC nearby the installation or the machine, is difficult to face the task of making some modification or backups by downloading/uploading the PLC program.

For this purpose, there’s a way to download/upload the PLC program directly from/to a USB memory stick through the DOP HMI.

Picture 1

Let’s explain the procedure in few steps assuming the case of downloading program from USB to PLC:

1. Copy the PLC program (.DVP) into an USB memory stick

2. Insert the memory stick into the USB port of the HMI

3. Enter the system menu of the HMI by pressing the “SYSTEM” button (at the rear side of the HMI) for few seconds. You will hear a “bip” sound

Picture 2

4. Enter the “Up/Download” sub menu

5. Select “HMI <->PLC” transfer mode by navigating through the  “LEFT” and “RIGHT” buttons at the bottom

Picture 3

6. Click “USB:\” on the left part of the screen and select the PLC program file you want do download

7. On the right part of the screen, select the COM port that is connected to the PLC (COM1 in this example)

Picture 4

8. After selecting COM1, HMI will search PLC automatically

9. Once the PLC is found by the HMI, user can download the program  by pressing “Download” button

Picture 6

Important note: The file name in the PLC to be uploaded or downloaded using this function must be DVP-xxx.dvp (xxx must be a number between 000 and 999.)











Customize Keypad Feature For DOP-W

For DOP-W series HMI it is possible to customize the layout and input keys for the onboard keypad entry.

These are the default keypad options in DOPSoft:

These options include all the basic keys that are needed in most applications but sometimes the users needs to customize the character entry for their design.

Example 1 : Customer would like to use the HMI for product rating system and log their details such as email address. For this the “@” character is needed which is not available on the custom keypad.

Solution: Please see link below for short video demonstration and also attached DOPSoft program.

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.
