SNMP network protocol
Properties
SNMP (Simple Network Management Protocol) is the standardized protocol for diagnostics
of the Ethernet network infrastructure. In the office setting and in automation engineering,
devices from many different manufacturers support SNMP on the Ethernet. SNMP-based
applications can be operated on the same network in parallel to applications with PROFINET
IO.
Configuration of the SNMP OPC server is integrated in the STEP 7 Hardware Configuration
application. Already configured S7 modules from the STEP 7 project can be transferred
directly. As an alternative to STEP 7, you can also perform the configuration with the NCM
PC (included on the SIMATIC NET CD). All Ethernet devices can be detected by means of
their IP address and/or the SNMP protocol (SNMP V1) and transferred to the configuration.
Use the profile MIB_II_V10.
SNMP-based applications can be operated on the same network parallel to applications with
PROFINET IO.
Note
MAC addresses
During SNMP diagnostics, the following MAC addresses are shown for the ifPhysAddress
parameter:
Interface 1 (PN interface) = MAC address (specified on the front panel of the CPU)
Interface 2 (port 1) = MAC address + 1
Interface 3 (port 2) = MAC address + 2
Diagnostics with SNMP OPC Server in SIMATIC NET
The SNMP OPC server software enables diagnostics and parameter assignment of any
SNMP devices. The OPC server uses the SNMP protocol to perform data exchange with
SNMP devices.
All information can be integrated in OPC-compatible systems, such as the WinCC HMI
system. This enables process and network diagnostics to be combined in the HMI system.
