To communicate PLC and HMI you can check the HMI – 3 PLC Communication Example.Īnd to know how to connect the B series servodrive with out CPU, just follow the next Schem. So our intention in this post, is show you the Delta PLC tools to control one axis trough step and direction:Īs always the first is how to connect everything. The other advantage is that you don’t have to rack one’s brains thinking if that protocol is going to work or not, Step & direction is universal. There are several ways to control one axis.īut If you need to control position (no speed or torque), the Step & direction way is normally the simplest and cheapest way. 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.)
Once the PLC is found by the HMI, user can download the program by pressing “Download” button After selecting COM1, HMI will search PLC automaticallyĩ. On the right part of the screen, select the COM port that is connected to the PLC (COM1 in this example)Ĩ.
Click “USB:\” on the left part of the screen and select the PLC program file you want do downloadħ. Select “HMI PLC” transfer mode by navigating through the “LEFT” and “RIGHT” buttons at the bottomĦ. Enter the system menu of the HMI by pressing the “SYSTEM” button (at the rear side of the HMI) for few seconds. Insert the memory stick into the USB port of the HMIģ. Copy the PLC program (.DVP) into an USB memory stickĢ. Let’s explain the procedure in few steps assuming the case of downloading program from USB to PLC:ġ.
Hope this tutorial is helpful to all of you.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.įor this purpose, there’s a way to download/upload the PLC program directly from/to a USB memory stick through the DOP HMI. Press F1 when selecting the TCN Block to access online helpĥ- Inside the properties of the TCON block specify the IP address of the communication partnerĦ.1- Select “General” => “Protection” => “Permit access with PUT/GET communication from remote partner”ħ- Enter the “Properties” option of the System Data Block previously generated and disable the “Optimized block access” option This automatically generates an instance data block for the “TCON” function that you have to confirm with “OK”Ĥ- Set the Input and Output parameters of the TCON block. Settings on Siemens S7-1200 PLC side using TIA Portalġ- Inside the PLC program, the “TCON” system function block (SFB) has to be inserted in order to establish the communication with Delta HMIĢ- Open the Main Operation Block “OB1” and insert the “TCON” SFB as followsģ- In “Instructions” -> “Extended instructions” -> “Communications” -> “Open user communication”, open the “Others” folder and drag the “TCON” block to the operation block.
This tutorial is intended to help all who may have little knowledge either Delta HMI or Siemens PLC in order to make this communication easy to set.īy following the below steps, you will find an easy way to connect both devices using Ethernet as a communication media:ġ- In DOPSoft menu bar, go to “Options” => “Communication Setting”Ģ- Click on the Ethernet port and set the following parameters on the “Device” tabĢ.1- Create a new connection by means of the “+” button:Ģ.2- Select “S7 1200 (ISO TCP) protocol from the SIEMENS list Many users have faced the challenge to connect our DOP series HMI and Siemens S7-1200 PLC.
