8.9 SNMP
The Simple Network Management Protocol (SNMP) is the standardized protocol for
diagnosing and configuring the Ethernet Network infrastructure. SNMP-based applications
can be operated parallel to applications with PROFINET on the same network.
Properties
The IM 153-4 PN supports the SNMP Ethernet service. LLDP-MIB and MIB-2 (RFC1213) are
supported. R / W objects can be changed using SNMP tools and are saved in the module.
Following replacement with a factory-new module, the R / W objects of the interface module
are set to factory settings.
Resetting SNMP parameters to factory settings
NOTICE
When factory settings are restored, the stations in a line can fail.
"Reset to factory settings" is only possible if the IO device is not exchanging data with an IO
controller.
To reset retentively-stored SNMP parameters to factory settings (
higher), select Target system > Ethernet > Edit Ethernet node and press the Reset button
under Reset to factory settings.
The following data is not deleted when resetting:
● The MAC address
● I&M data
Having deleted the device name you can then assign a new device name. Open the
properties dialog box of the interface module in HW Config. Confirm the properties dialog
box without entering a device name in the "Assign device name" field.

Note
With the IM153-4AA01 interface module it is possible to reset to factory settings also
during the data exchange with a controller. The station is unavailable during this
resetting.
The maintenance data 1, 2 and 3 (I&M1, I&M2 and I&M3) are also reset with this
interface module.
Note
Deleting the device name
The device name is deleted after resetting to factory settings
