Simple Network Management Protocol (SNMP)

SNMP is a network protocol to monitor and control routers, servers, switches, printers, computers etc. from a central station. The protocol controls the communication between the devices and the monitoring station.

SNMP Service SL Library

Use the SNMP Service SL library to read out information from devices via the SNMP protocol. The library provides function blocks for sending and receiving SNMP messages and is part of the software package "IIoT Libraries SL".

In the integrated library documentation (within the library manager) you find further information on a respective library as well as on the functionality and application area of the contained function blocks.

Application example

An ‎⮫ application example describes the SNMP communication in a scenario in which an AC500 PLC acts on the one hand as SNMP agent and on the other hand as SNMP manager. In this case, the SNMP protocol is used for network monitoring. The PLC can receive SNMP requests and respond to them as an agent. As a manager, it can query managed information from any network device that supports SNMP.
