5.9.4 Synchronization of the TIM time of day by the CPU
Apart from the option of synchronizing the TIM by a master station or using NTP, the TIM
can also be synchronized by its local CPU.
Please note: You require an Ethernet CP in the 400 station.
Follow the steps described below when configuring in STEP 7.
Time-of-day synchronization of the TIM by the 300 CPU
1. In the properties dialog of the CPU, open the "Diagnostics / Clock" tab.
2. In the "Clock" box, select the option "As master" in the "On PLC" drop-down list and
select the time interval.
3. Close the properties dialog of the CPU.
4. Open the properties dialog of the TIM with the "Time Service" tab.
5. Select the backplane bus and set the synchronization cycle to the same setting as
configured on the CPU.
6. Close the dialog and save.
