Configuration of an IE switch using SNMP
Using SNMP (Simple Network Management Protocol), a Network Management Station can
configure and monitor SNMP-compliant nodes, such as an IE switch. To allow this, a
management agent is installed on the node with which the management station exchanges
data using Get and Set requests. The X-200 IE switches support SNMPv1, SNMPv2 and
SNMPv3.
The configurable data is stored on the IE switch in a database known as the MIB
(Management Information Base) and this can be accessed by the management station or by
Web Based Management.
SIMATIC NET SNMP OPC Server
The SNMP OPC server makes the SNMP information from TCP/IP networks with SNMP
available on the OPC interface. With the aid of the SNMP OPC server, any OPC client
systems (such as WinCC) can now access diagnostics and parameter data of SNMP-
compliant components.

Non SNMP-compliant components can also be included in the plant visualization using their
IP addresses. This allows, for example, not only simple device diagnostics but also detailed
information such as redundant network structures or network load distributions of entire
TCP/IP networks to be displayed. With the additional monitoring of this data, device failures
can be detected and localized quickly. This increases operational safety and improves plant
availability.
With STEor alternatively NCM PC, you configure which devices are monitored by the SNMP
OPC server.
