SNMP is used for simple, network-based device management. For example, PROFINET devices support the following SNMP functions:
- Monitoring and diagnostics of the network topology through network management services
- Provision of network-specific information, such as details about the IP stack
SNMP is disabled in the basic settings of a PLC. You can enable or disable SNMP via the configuration. You can configure SNMP both for PLCs and for IO devices for the following access types:
- Read and write access
- Read access only
To determine whether IO devices support configuration of SNMP, refer to the respective equipment manuals. IO devices that support the configuration of SNMP behave as follows during configuration or initial loading of the hardware configuration:
- SNMP is disabled by default. Changed SNMP settings do not take effect until the hardware configuration has been loaded.
