SNMP

The IM151-3 PN supports the Ethernet service SNMP. MIB-2 (RFC1213) is supported. R/W
objects are changeable using SNMP tools and are stored in the device.
Remanent stored SNMP parameters are reset to default settings (
higher) in HW Config dialog "Target system > Ethernet > Edit Ethernet nodes" "Reset" button
under "Reset to default settings". If the module has a station name (stored on a SIMATIC
Micro Memory Card), this will not be deleted. The device name on the SIMATIC Micro
Memory Card is not deleted since the SIMATIC Micro Memory Card does not form part of
the IM151-3 PN. Likewise, the IP address, which is only available when the module is
switched on, is not erased. As a security measure this service is only enabled when the IO
device is not in data exchange mode.

• Data for a firmware update
Service life of a SIMATIC Micro Memory Card
The life of an SIMATIC Micro Memory Card depends substantially on the following factors:
• Number of deletion or programming operations
• External factors, such as ambient temperature
At an ambient temperature up to 60 °C, a SIMATIC Micro Memory Card has a useful life of
10 years at maximum 100,000 write/delete operations.
