6.3.6.1 Configuration and diagnostics over SNMP
Configuration of an IE Switch X-200 over SNMP
A network management station can configure and monitor a SCALANCE X-200 using SNMP
(Simple Network Management Protocol). To allow this, a management agent is installed in
the IE Switch X-200 with which the management station exchanges data using Get and Set
requests. X-200 IE switches support SNMP V1, V2, and V3.
The configurable data is in a database on the IE Switch X-200 known as the MIB
(Management Information Base). The management station or Web Based Management can
access this MIB.
SIMATIC NET SNMP OPC Server
The use of the SNMP OPC Server Windows application allows access to device information
over the OPC interface. This allows network visualization, system diagnostics, and plant
status monitoring to be implemented on any OPC client systems. OPC client systems
include, for example, OPC Scout, SIMATIC HMI/SCADA, Office applications. This allows, for
example, not only simple device diagnostics but also detailed information such as redundant
network structures or network load distribution to be visualized. This increases operational
safety and improves plant availability. The SNMP OPC Server has the following properties:
● Full integration in the SIMATIC NET OPC server environment.
● Parallel use of SNMP with other communication protocols such as PROFINET or S7
communication.
● Integrated MIB compiler for creating device profiles. The SNMP OPC MIB compiler can
only compile SNMP V1 objects.
● Configuration and project engineering in STEP 7/NCM as of version V5.2
Supported MIBs
A distinction is made between standardized MIBs defined in RFCs and private MIBs. Private
MIBs contain product-specific expansions that are not included in standard MIBs.
An IE Switch X-200 supports the following MIBs
● RFC1213: MIB II (all groups except for egp, transmission, at)
● Bridge MIB
● Private MIB
Access to the private MIB of an IE Switch X-200
You can save the private MIB of the IE Switch X-200 in WBM menu "System Save & Load
HTTP" with the "Save Private MIB" button.
