1 Properties / Services

STime-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).

STime 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)

SAddressing using a factory-set MAC address

The CP can be reached over the default MAC address to allow an IP address to be assigned.

SSNMP 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:

SIP 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/).

SWeb 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.
