How the BMENOP0300 NTP time synchronization works ?
Issue:
Product Line:
M580 CPUs, BMENOP0300
Environment:
EcoStruxure Control Expert, Windows 10
Resolution:
The BMENOP0300 IEC61850 communication module does not have an internal clock. It requires synchronization with an external time source, which can be either:
- An NTP server, or
- The CPU time.
Time synchronization process:
-
At PLC startup:
The BMENOP0300 retrieves the time from the CPU and uses it as its local time. This occurs only once during power-up. -
If an NTP server is configured in the BMENOP0300 settings:
The module automatically switches to the NTP server for time synchronization. -
If no NTP server is configured:
The BMENOP0300 continues to use the CPU time obtained at startup.
Important:
To ensure correct time usage for services such as syslog and generated reports, the following settings must match in both the IEC61850 Configuration Tool and the EcoStruxure Control Expert project:
- Daylight Saving Time (DST) option
- Time zone configuration
