Configuring time synchronization

5.8 Configuring time synchronization on an AS

Time synchronization (V7.1)

102 Function Manual, 03/2009, A5E01216578-01

Result

The communications processor uses the SIMATIC mode for time synchronization.

Note for redundant systems

If in a SIMATIC H-station (high-availability process control systems) multiple CPs are present

that are connected to the same network, then time synchronization can only be switched on

for one of these CPs. The following table shows the possible arrangement:

Plant bus CPU 1/rack 1 CPU 2/rack 2

Plant bus 1 CP 1/1 Time synchronization enabled CP 1/2 Time synchronization disabled

Plant bus 2 CP 1/2 Time synchronization disabled CP 2/2 Time synchronization enabled

Setting CP 443-5 Extended (PROFIBUS DP)

To configure time synchronization for the CP443-5 Extended, proceed as follows:

1. Open the project in SIMATIC Manager.

2. Select the station that will be synchronized.

3. Open the configuration of the hardware.

4. Select the CP 443-5 Extended, followed by Edit > Object Properties.

The "Properties - CP 443-5 Ext" dialog box opens.

5. Switch to the "Operating Mode" tab.
