6.11 SNMP agent
SNMP (Simple Network Management Protocol)
SNMP is a protocol for managing networks. To transmit data, SNMP uses the connectionless
UDP protocol.
The information on the properties of SNMPcompliant devices is entered in MIB files (MIB =
Management Information Base).
The CP supports data queries using SNMP in version 1. It delivers the content of certain MIB
objects according to the standard MIB II, LLDP MIB, Automation System MIB and
MRP Monitoring MIB.
MIB file and SNMP profile file
You will find the MIB file and the SNMP profile file of the module in the STEP 7 installation in
the folders "S7DATA" > "snmp" under the name of the module.
Further information
For more detailed information on working with MIB files, refer to the documentation of the
SNMP client you are using (example of an SNMP client: SNMP OPC server from SIMATIC NET).
For more information on SNMP, refer to the SNMP manual:
