9.9 SNMP agent

SNMP (Simple Network Management Protocol)

The CP supports data queries via SNMP in Version 1. It returns the contents of

certain MIB objects according to the MIB II standard, LLDP MIB and automation

system MIB.

SNMP is a protocol for managing networks. To transmit data, SNMP uses the

connectionless UDP protocol.

The information on the properties of SNMP-compliant devices is entered in MIB

files (MIB = Management Information Base).

Where to find 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).

You will find more information on MIB on the following SIMATIC NET Internet
