The SNMP (Simple Network Management Protocol) is a high layer TCP/IP protocol used mainly by IT departments to manage and monitor WAN and LAN networks. With same features as classical SCADA package used in the industry, the SNMP Manager software package provides a MMI (Man Machine Interface) including an Alarm Management module, real-time graphics, etc…

The most popular SNMP Managers are:

• UNICENTER TNG from Computers Associates
• TIVOLI from IBM
• OPENVIEW from HP
• etc…

The eWON makes the interface between the field and the SNMP protocol allowing to manage technical data such as temperature, level, pressure, switch,... with a standard SNMP manager.

The eWON supports SNMP version 1 and is provided with its own MIB.

Every data gathered by the eWON trough its own IO or by UNITELWAY, MODBUS or ASCII protocols can:

• be associated to a SNMP OID (Object ID) to assume SMNP visibility
• generate TRAP when an alarm appears ( see eWON Alarm Management features)
