The DirectLink function of the HMI Delta is used to communicate with the PLC and HMI, making it possible to upload / download and monitor both with a single cable.
In cases where the PLC is connected to the HMI and the PLC communication ports are not accessible, you can use this feature.
To access the PLC via the HMI, it must be configured as [Delta (DVP / AS / AH) PLC] and set the same communication format as the PLC. Delta's standard serial format is: (RS485 / 232: 9600, 7, E, 1).
In DOPSoft 2.0, go to Options> Configuration> Others> USB Download.
1. For Windows XP, the upload / download mode must be set to 0 (Normal Mode).
2. For Windows 7, 8 or 10, the upload / download mode must be set to 1 (Disk Mode).
3. If USB permission is restricted, set to mode 2 (CDC Mode).
4. There is an automatic detection mode (Auto) that automatically detects the connection mode.
Note: For Windows 10, CDC mode is the most recommended.
If the connection between the HMI and the computer is not established before the project starts, it will not be possible to download or upload the new settings. In this case, the user has to configure the system by pressing the system menu from the back of the HMI. Please follow the steps below.
1. Press the system menu button on the back of the HMI for 2 to 3 seconds. When the button is pressed, the bell will respond with a beep as a notification. For DOP-B models that do not have a system button on the rear, you must, with the HMI turned on, press on any corner of the screen for a few seconds until you hear the beep. After the beep, quickly press the upper left corner of the HMI.
2. When entering the HMI system menu, press the screen to enter System Setting> Misc. > USBCommMode and set the mode to 0 or 1 or 2.
Note: 0 = Normal, 1 = Disk and 2 = CDC
3. After configuration, press the upper right corner to return to the HMI project screen.
note:
Models DOP-B05S100, B05S101, B07S201 and B07S211 do not have the CDC (2) communication option, therefore, they are not compatible with Windows 10. In this case, it is recommended to use a virtual machine or a PC with Windows XP SP2.
2. For DOP-100 series HMI
In DOPSoft 4.0, go to Options> Configuration> Others> USB Download.
1. For Windows 7, 8 or 10, the upload / download mode must be set to 1 (Disk Mode).
2. If USB permission is restricted, set to mode 2 (CDC Mode).
3. There is an automatic detection mode (Auto) that automatically detects the connection mode.
Note: For Windows 10, CDC mode is the most recommended.
If the connection between the HMI and the computer is not established before the start of the
project, you will not be able to download or upload the new settings. In this case, the user has to configure the system. Please follow the steps below.
1. To access the system, press on a blank space on the screen for more than 3 seconds. After that you should hear a ringing sound. After hearing the buzzer sound, press the upper left corner within 1 second
to enter the system screen.
2. When entering the HMI system menu, press the screen to enter System Setting> Misc. > USB Comm. Mode and set the mode to Disk or CDC.
Note: For Windows 10, CDC mode is the most recommended.
After configuration, press “Home” and then the upper right corner to return to the HMI project screen.
Before applying DirectLink, make sure that the communication between the HMI and the PLC works correctly via RS232 / RS485. Your personal computer must connect to HMI via USB cable.
3. Select [DirectLink (USB)] as the connection type and select [USB / Disk mode] as the HMI's USB mode.
Before applying DirectLink, make sure that the communication between the HMI and the PLC works correctly via RS232 / RS485. Your personal computer must connect to HMI via USB cable.
1. Go to the HMI system directory> [System setting]> [MISC.] And set USBCommMode to 2 (CDC).
2. Open COMMGR and click [Add] before activating in ISPSoft.
3. Select [DirectLink (USB)] as the connection type and select [CDC mode] as the HMI's USB mode and choose the COM port created by the HMI.
Note: To find out which port is the HMI, go to device manager.
1. Open ISPSoft and go to [Tools]> [Communication Settings].
2. Select the Driver created previously (DISK or CDC) and place the [Station Address] equal to 1. (PLC modbus address.)
3. When the configuration is complete, go to [PLC]> [System Information] to check if the communication was successful.
4. If the communication is successful, a window will appear with the PLC information.
5. It is now possible to upload / download and monitor the PLC
