CP 343-1 Lean for Industrial Ethernet / Manual Part B3L
Release 03/2007
C79000-G8976-C198-04
S Time-of-day synchronization over Industrial Ethernet using the following
configurable modes:
− SIMATIC mode
The CP receives MMS time frames and synchronizes its local time and the
time of the CPU (accuracy approx. +/− 1 second);
or
− NTP mode (NTP: Network Time Protocol)
The CP sends time-of-day queries at regular intervals to an NTP server and
synchronizes its local time of day and the time of the CPU (accuracy approx.
+/− 1 second).
S Time of day for the diagnostic buffer
If a time master exists (using the NTP or SIMATIC mode), the time for the
CP-internal diagnostic buffer is synchronized over the LAN (accuracy approx.
+/− 10 ms)
S Addressing using a factory-set MAC address
The CP can be reached over the default MAC address to allow an IP address to
be assigned.
S SNMP Agent
The CP supports data queries over SNMP in version V1 (Simple Network
Management Protocol) according to the MIB II and LLDP MIB standard.
You will find more information on MIB in the manual “Commissioning PC
Stations” on the SIMATIC NET Manual Collection or at the following
SIMATIC NET Internet page:
http://support.automation.siemens.com/WW/view/en/15177711
S IP configuration
You can configure how and with which method the CP is assigned the IP
address, the subnet mask and the address of a default router.
It is also possible, as an alternative, to assign the connection configuration to
the CP using STEP 7 or using a block interface in the user program (FB55:
IP_CONFIG) (see /Part A/).
S Web diagnostics
With the aid of Web diagnostics, you can read out the diagnostic data from a
station connected over the CP to a PG/PC with an Internet browser.
