Example: Configuring the NTP server

Configuring time synchronization with your own NTP server
Automation task
You use your own server in your network. Your own server offers the following advantages:
● Protection against unauthorized external accesses
● Every device that you synchronize with your own NTP server uses the same time.
You want to synchronize the CPUs of your S7-1500R/H redundant system with this NTP
server.
Conditions and parameters
● You have your own NTP server in your network with the IP address 192.168.1.15.
● S7-1500R/H redundant system
Solution
1. Navigate to "Properties > General > PROFINET interface > Time synchronization > NTP
mode" in the properties of the first CPU.
2. For "Server 1:", enter the IP address of the NTP server: 192.168.1.15.
Figure 9-16
3. Repeat steps 1 and 2 for the second CPU.
4. Download the hardware configuration to the primary CPU.
Result
The S7-1500R/H redundant system synchronizes the time with NTP server 192.168.1.15.
