Set Ntp Time Synchronization - Siemens SINAMICS S120 Function Manual

Communication
11.8 Time synchronization between the control and converter
Changing the time format
The time format is entered via parameter p3100. This parameter cannot be changed online
To change the value, proceed as follows:
1. In STARTER, using the "Project > Connect to target system" function activate the
ONLINE mode.
2. Upload using the "Target system> Load > Project to PG" function.
3. In STARTER, using the "Project > Disconnect connection to target device" function exit
the ONLINE mode.
4. Offline, in the expert list of the control unit, make the setting p3100 = 1.
5. Reactivate the ONLINE mode.
6. Carry out a parameter download ("Target system > Load > Load project to target
system") followed by copy from RAM to ROM.
You have now changed over the converter time format to UTC format.
Application example
You can find an application example for SINAMICS time synchronization in the SIEMENS

Set NTP time synchronization

Setting time synchronization with NTP
1. Using p3100, changeover the time format from operating hours into the UTC format (see
"Changing the time format").
2. Set the synchronization technique NTP (p3103 = 4).
3. Set the IP address of the NTP server used (p3105[0...3]).
– Special case: To use a PROFINET controller as NTP server, set p3105[0...3] = 0.
4. Set the local time zone (p3106).
Result:
After successful NTP time synchronization, the NTP time is converted to the already existing
UTC time.
If a previously defined tolerance window is exceeded, then alarm A01099 is output. The
tolerance window for time synchronization is defined using p3109. If alarm A01099 occurs,
then generally the synchronization interval is to large.
If the set NTP server cannot be reached within 10 minutes, the warning A01097 is output.
