11.10.1 Example: Configuring and changing NTP server
Configuring time synchronization with your own NTP server
Automation task
You use your own server in your network. Your own server provides you with the following
advantages:
● Protection against unauthorized accesses from outside
● Every device that you synchronize with your own NTP server uses the same time.
You want to synchronize the ET 200SP CPU with this NTP server.
Conditions and parameters
You have your own NTP server in your network with the IP address 192.168.1.15.
They are located in STEP 7 in the Inspector window in the properties of the PROFINET
interface X1.
Solution
1. Navigate to "Properties > General > PROFINET interface > Time synchronization > NTP
mode".
2. For "Server 1" enter the IP address of the NTP server: 192.168.1.15.
Figure 11-10 Example: Configuring the NTP server
3. Download the hardware configuration to the CPU.
Result
The ET 200SP CPU synchronizes the time with the NTP server 192.168.1.15.
