Further functions
Timeofday synchronization over Industrial Ethernet using the NTP mode (NTP: Network Time
Protocol)
The CP sends timeofday queries at regular intervals to an NTP server and synchronizes its
local time of day.
The time is also be forwarded automatically to the CPU modules in the S7 station allowing
the time to be synchronized in the entire S7 station.
Security function: The CP supports the NTP (secure) protocol for secure time-of-day
synchronization and transfer of the time of day.
Addressable with the factoryset MAC address
To assign the IP address to a new CP (direct from the factory), it can be accessed using the
preset MAC address on the interface being used. Online address assignment is made in
STEP 7.
SNMP agent
The CP supports data queries over SNMP in version V1 (Simple Network Management
Protocol). It delivers the content of certain MIB objects according to the MIB II standard and
Automation System MIB.
If security is enabled, the CP supports SNMPv3 for transfer of network analytical information
protected from eavesdropping.
