5.10 System time with SNTP

Requirement

• COM190 communication module

• NTP time server

• SENTRON powerconfig configuration software, version 3.17 or higher, for commissioning

(optional)

To activate the SNTP function and enable writing of parameters via the Ethernet connection,

the remote parameterization protection (DIP switches) of the COM190 communication

module must be deactivated. You can find information on remote parameterization

protection in the Equipment Manual; see Chapter Reference documents (Page 5).

If two COM190 communication modules are operated simultaneously on the 3WA circuit

breaker, the system time update via SNTP can take place either via the communication

module with role A or the communication module with role B.

Note

According to the Siemens Cyber Security Disclaimer, the COM190 communication module

must not be operated in public networks. The SNTP function of the COM190 is therefore

designed for a local NTP time server in closed networks.

5.10.2

Settings

circuit breaker:
