DL8 시리즈 Features
- Direct Access (1 : 1)
-
- I/O signal status in the DL8 web server can be directly monitored and manipulated with an internet browser.
- I/O signal status in the DL8 web server can be directly monitored and manipulated with an internet browser.
- Cloud Access (N : N)
-
- The DL8 operating as FTP client uploads web use files to a cloud server.
- Multiple users can access it at once without extra load at the DL8.
- Multiple DL8 data can be managed by directories in the server.
-
- I/Os located within 500-meter distance can be collected and accessed via single DL8 module.
- The remote I/O model R7E, R6-NE1/2, R3-NE1 and other general Modbus/TCP slaves can be connected.
- Local I/O data collected at the DL8 can be polled by a SCADA system via internet or intranet (LAN).
*1. Pi is for pulse accumulation and 32-bit signed integer data.

- Events can be reported by text message.
- Selected channel data can be attached.
- Regular reporting and test mailing are also possible.
- SMTP over SSL encryption
- Events can trigger an alarm contact at a discrete output module.
- Specified Do can be turned on after a mail delivery
-
- Specified channel data can be converted into user defined CSV files and uploaded to an FTP server.
- Data transfer in the preset time intervals
| Data | 32 channels selected among Ai, Di, Di count, Pi, Do, Ao |
| Storing interval & FTP transfer cycle | 1 / 2 sec : Transferred every 1 min / 10 min / 1 hour (selectable) 5 / 10 / 30 sec : Transferred every 10 min / 1 hour (selectable) 1 / 2 / 5 / 10 / 30 min : Transferred every day Dateline can be specified. |
-
- Data is sampled and stored in CSV format in an SD card.
- The host supervising system (PC) can upload CSV data files from the DL8 operating as FTP server.

-
- Peer-to-peer connection between Modbus/TCP slaves
- Di/Do and Ai/Ao signal marshaling is easily set up on the DL8
- Remote multiplex transmission on IP network
EASY SETUP
Simply choose input and output on the list.
-
- DL8 allows I/O expansion by connecting with the SLMP-compatible CPU unit of Mitsubishi programmable-controller MELSEC; and collectively handles data from measuring points in multiple locations.
- Type E is added with 'Expanded Communication' functions of SLMP client, HTTPS, and FTPS protocols.
