1.3 Other services

S Media redundancy (MRP)

Within an Ethernet network with a ring topology, the CP supports the media

redundancy protocol MRP. You can assign the role of redundancy manager to

the CP.

If you are using IRT communication, no media redundancy is supported.

S Time-of-day synchronization over Industrial Ethernet using the following

configurable modes:

− SIMATIC mode

The CP receives MMS time messages and synchronizes its local time and

the time of the CPU.

(accuracy approx. +/− 1 second)

You can choose whether or not the time of day is forwarded. The forwarding

direction can also be selected (station > LAN or LAN > station).

Synchronization using the SIMATIC mode is only possible on the

PROFINET interface.

− 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).

Via the gigabit interface, synchronization is possible only with the NTP

mode.
