The Simple Network Management Protocol (SNMP) is used to provide the data and services required for managing a network.
The data is stored in a Management Information Base (MIB). The SNMP protocol is used to read or write MIB data. Implementation of the Ethernet SNMP services is minimal, as only the compulsory objects are handled.
M241 controllers support the standard MIB-2 objects.
This table presents the supported standard MIB-2 server objects:

The values written are saved to the controller via SNMP client tool software. The Schneider Electric software for this is ConneXview. ConneXview is not supplied with the controller. For more details, refer to www.schneider-electric.com.
The size of these character strings is limited to 50 characters.
The M251 Logic Controller includes an SNMP client library to allow you to query SNMP servers. For details, refer to the SNMP Library Guide.
