Checking the communication contents with the SNTP server
●
You can check the communication contents with the SNTP server through the values of the HMI Special Internal
Relays and the HMI Special Data Registers.
■ LSM57
When the value of this bit changes from 0 to 1, get the current time from the SNTP server. The acquired current time
is written to the MICRO/I internal clock and stored in the MICRO/I internal current time data (LSD13 to 19).
■ LSD29
The execution result of communication with the SNTP server is stored.
Status
0: Successfully Completed
2: Timeout error
4: Other error
LSD30
■
The elapsed time (0 to 65535 minutes) from the time last obtained from the SNTP server to the current time is stored.
If the current time is successfully obtained, the value will be reset and the elapsed time will start counting. Even if it
fails to get the current time, the elapsed time counting continues without interruption until it succeeds.

• Host Name of the SNTP server is incorrect.
• IP address of the SNTP server is incorrect.
• A connection cannot be made to the preferred DNS server and alternate DNS server.
MICRO/I cannot perform communication with SNTP server
