Dual modem, double communication channel for a secure monitoring
Equipped with two comumunication channels, for a reliable, secure and redundant remote monitoring and control; it’s the ideal solution for all the applications, that require the highest reliability in the acquisition and logging of data from unattended stations. The Dual Modem WE500 includes two completely indipendent communication channels on mobile network GSM/GPRS/UMTS/HSPA. They allow the parallel interaction with two different carriers. The redundancy of the communication channel is granted : the system is composed of two internal modems, two antennas and two SIM cards. This redundancy, that is unique in the market, provides enhanced availability and reliability of the system, even in case of mobile network failures.
Monitors the system status and detects parameters changes. WE500 provides a sophisticated events system that allows to send SMS, emails or rings when it detects changes in activation threshold, in one or more parameters simultaneously or even based in mathematical expressions.
Stores periodically the system parameters specificed by the user. All the monitored parameters and triggered events are stored in the capable internal memory, in an external USB key or they can even be sent to a web portal at user defined intervals.
Through a VPN channel WE500 provides a direct and transparent communication to the monitored devices and machines. It allows to interact in real time and provide remote assistance.
Remotely handles the different functions of a system: switching on/off, parameters settings and thresholds activation. WE500 provides different communication mechanisms for system controlling, including the most popular protocols of the Indystry 4.0 (Modbus, TCP/IP and others).
Connectivity 2G-3G-4G LAN AND WLAN
Expandable I/O Module complete with 8 digital inputs, 2 analogue inputs and 2 digital outputs on board
The redundancy is provided through three different policies that can be selected according to specific users needs:
SWITCH MODEM ON ERROR
Modem A is always working, but if a connectivity issue arises, such as continuous data connection failures or modem malfunctioning, it switches to modem B and remains on this modem until a new issue arises on this modem, causing switch back to modem A. This is the default mode.
Each modem works for a given period of time. When that period timeouts, it switches to the other modem. The timeouts of each modem can be different. This policy could be useful when the user wants to consume the SIMs credit evenly. If modem A is currently working and presents an issue such as continuous data connection failures or modem malfunctioning, it switches to modem B and remains on this modem until its period times out. At that time, it switches back to modem A.
PRIORITY TO GIVEN MODEM
One of the two modems, eg. modem A, is always working . If a connectivity issue arises, such as continuous data connection failure or modem malfunctioning, it switches to modem B, but it keeps monitoring modem A until it recovers. At that point it switches back to modem A and remains on it.
Since only one modem works at any given time, every time that the system switches from one modem to the other for any reason, WE500 can send notifications via SMS or email to selected users. It also logs these kind of events for future reference.
Simple and intuitive user interface
WE500 can be completely configured and monitored directly through its web interface. There is no need to install additional software.
All data monitored by WE500 can be displayed in real-time using multi-trace graphics or tabulates.
The new Dashboard allows to customize the device interface according to the specific requirements of the application.
It provides a wide choice of ready-to-use tools and allows to upload external images or graphic elements, in order to develop a dedicated and intuitive visualization of the performance of each single plant or device.
Its functioning requires only a power source and an enabled SIM card.
WE500 can be completely configured and monitored through the internal web based interface.
The functioning of the device doesn’t need any kind of human interaction.
WE500 is the ideal device for custom solutions. Its hardware and software can be easily customized according to the specific requirements of the customer, since it has been entirely designed, developed and manufactured by Nethix inside the Italian factory.
For a centralized management of extensive installations, that contain unlimited number of devices, Nethix offers its Cloud service. Real-time control and monitoring on a complete and unique platform, available at any time and from any device.
