The eWON is a IPR - Industrial Programmable Router - integrating not only the advanced functions of any advanced RTU or telemetry programmable controller (datalogging, management of alarms, scripting, integrated modem...) but offering moreover : 

	an 100% Internet compatibility: Web pages server, transmitter of emails, SMS, files by FTP
	a complete agent SNMP, exposing a selection of variables (via of OIDs) and generating exceptions (traps)
	a set of intelligent bridges towards programmable controllers and acquisition units (MPI, Profibus, Unitelway, XIP, MODBUS-RTU, MODBUS-TCP, ASCII, Siemens controllers, Schneider, etc...)
	a complete TCP/IP routing between its telephone line (PPP) and its Ethernet connection as well as a RAS type server
	a true local supervision serving standard and customized Web pages

Supervision Architecture

A solution of remote supervision and monitoring based on TOPKAPI SCADA software connected to a network of eWONs makes it possible to combine the advantages of a centralized architecture (multi-stations management and  control, generation of reports and consolidated balance-sheets) with those of a decentralized architecture (teleprocessing of the interventions, redundancy, telediagnosis,
remote maintenance, etc...) 

Supervisor TOPKAPI dialogues with the automats eWON by a modem connection or direct connection with protocol TCP/IP (Ethernet network, Internet, Intranet) :    

	Management of the real time data. Immediate access to the real time data and remote controls after the establishment of connection.
	Reception and treatment of the whole of the time stamped data, and automatic incorporation to the logs and sampling files (1).
	Processing of the remote controls (logic and analog).
	Management of the incoming calls (reception of alarms, periodic calls) and outgoing (periodic and on event, manual).
	Follow-up of the durations and frequencies of communication, call test (2).

^{(1) Whatever the form and the origin of the horodatées data (newspapers, samplings, assessments), TOPKAPI exploit them without restriction for all the variables of supervision which refer there.
(2) The call test consists in checking that connections are established recurringly, in order to detect the breakdowns of the stations.}
