SNMP OPC server
2
■
Overview
•
Status monitoring of SNMP-capable devices in any OPC client
systems; e.g. SIMATIC WinCC/PCS 7
•
Easy access to SNMP-capable devices over the OPC
interface
•
Devices without SNMP agents can be monitored using the
ping mechanism
•
Configuration with STEP 7 (up to STEP 7 V5.5) or NCM PC
•
Ready-to-use SNMP diagnostics profiles for Siemens devices,
e.g. SCALANCE X/W
•
Generation of any SNMP diagnostics profiles by means of the
integral MIB compiler
•
Easy setup of the monitored devices with the help of an
Autodiscovery function
■
Benefits
•
Network view and process view in a single system
•
Easy network diagnostics in SIMATIC HMI/SCADA systems
and office applications
•
Easy configuration and engineering without the need for
detailed knowledge of SNMP:
embedded in the SIMATIC tool landscape
•
It can operate in parallel with other communication protocols
■
Application
The SNMP OPC server makes data available for the administra-
tion of TCP/IP networks for any OPC client systems.
SNMP (Simple Network Management Protocol) is a protocol that
has been specifically designed for administration of TCP/IP
networks. The individual nodes in the network (network compo-
nents or data terminals) are equipped with a so-called SNMP
agent that provides information in structured form.
OPC (Openness, Productivity & Collaboration) provides a
standardized, open, multi-vendor interface for automation
engineering.
The SNMP OPC server supports access to device information
over the OPC interface. This means that network visualization,
system diagnostics and plant status monitoring can be imple-
mented in any OPC client systems (with OPC clients such as
WinCC, WinCC flexible, PCS 7). In addition to simple device
diagnostics, detailed information such as redundant network
structures or network load distribution can be displayed. This
increases the operational safety and improves the availability of
the plant.
The device information can be visualized according to individual
requirements and can be adapted to the special requirements of
the respective customer installation. The information that is
made available can also be integrated into the signaling system
and alarm log of an HMI/SCADA system for example.
Using the SNMP information, it is possible to expand an existing
HMI/SCADA system as far as a customer-specific network
management station.
The SNMP OPC server can be operated over the following
interfaces:
•
CP 1613 A2 (PCI)
•
CP 1623 (PCIe)
•
CP 1628 (PCIe)
•
Integrated Industrial Ethernet interface or CP 1612 A2
