+ I/O mapping + User-defined browser viewYes DL8 Series System Concept M-System's model DL8 is a remote terminal unit with basic web server function. Various sensor signals are gathered from built-in I/O modules or remote I/Os connected through Ethernet Modbus/TCP, and monitored through Intranet or Internet using a web browser.
Web Browser Views Users do not need any additional application program to view the data. User-friendly browser views are already installed: Data, Trend and Event Log views. Each one is basic but useful, designed for ease of browsing on a small screen of smart phones and tablets.

Data can be uploaded to a cloud server or a PC by FTP, so that multiple users can access it at once without overloading the local DL8 module. Local data logging in CSV format is available by using an SD card memory, thus the DL8 functioning as a stand-alone data logger.
Each signal channel is available with alarm threshold setting to trip alarm contact outputs by adding discrete output modules for buzzers and lamps. E-mailing with a preset message attached with event data is also possible. Mails can be used for regular reporting purposes, too.
At the maximum of 32 analog signals, 64 each of discrete inputs and outputs, and 32 pulse signals can be handled by one DL8 module. M-System's remote I/O model R7E, R3-NE1 and other Modbus/TCP slaves can be connected. Modbus RTU devices such as Multi Power Monitor L53U are connected through a gateway unit (model: 72EM2). I/O data is assigned by using only general address information (IP address, node number and channel), so that other manufacturers' I/Os are also usable.
The DL8 functions as Modbus master to collect data from remote I/O, while it functions as Modbus slave when a supervisory monitoring system (SCADA) polls data of the DL8.
TypeFunctionsDescriptionsBrowse I/O signal status in the DL8 web server can be directly monitored with an internet browser. 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.I/Os located within 500-meter distance can be collected and accessed via single DL8 module. Report Events can be reported by texting.
Regular reporting and test mailing are also possible.Event can trigger an alarm contact at a discrete output module. Specific data can be converted into user defined CSV files and uploaded to an FTP server. Log 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. DL8 Series Setup
Network, I/O, web server, mail, FTP, logging and other parameters are set up by using the PC Configurator Software model DLCFG, connected either locally via a special cable (models: MCN-CON or COP-US) or remotely via network.
