Programming and supervision
WebLog is equipped by a software for the programming and the supervision by which, the programmer is able to set up the system quickly and the user to have the real time under control system. DevTool is a software based on graphic simple and intuitive interface, thanks to which you can set up inputs and outputs, users, alarms, the datalogger and relative sampling times. Furthermore DevTool allows to define the alarm events, the messages and the notification modes.

PlantManager is a software which allows:
− realtime systems monitor through the synoptic pages creation
− receive the alarms and the historical data of the peripheral units
− display the historical data in tabular or graphic format
− plan a tracebleness calendar of the operators assigned to the maintenance

Internet Connection
The internal GSM/GPRS modem allow WebLog to send data using internet and WEB protocols to act as a WEB client that sends data to a server. WEB server publish the data received from the WebLog to the users enable to this service.
