NTP/SNTP settings for ION9000

[p_dejarmy_encos]

Hello,

I have 4 ION9000 meters which are connected to an internet enabled ethernet connection, and have been trying to set them up to synchronize using NTP but I have not been able to. The meter is setup to synchronize every 5 minutes, but it doesn't do it. I have tried using the IP address of a windows NTP server, and also using pool.ntp.org but it doesn't work.

Could you please help me out?

Thanks.

First question, have you looked at the meter's eventlog?

You may see something like Time about to change/time change

If not using IPv6, does disabling this help?

Hi Charles,

There are no time events in the eventlog. Just checked it.

I've also disable IPV6 but it makes no difference.

If possible, can you run a wireshark trace for 3 intervals and contact technical support to start a case. Please include the wireshark trace, NTP server info, meter configuration report, eventlog, any screenshots etc.

It seem that you did not set something in clock module setup use advance option for ION Setup check this option.

Enable NTP Time Sync
Set this register to determine the meter’s NTP/SNTP time synchronization
behavior.
• NO: NTP and SNTP time synchronization are disabled.
• YES or SNTP: SNTP time synchronization is enabled. YES applies to meters
without NTP capabilities. SNTP applies to meters with NTP capabilities.
• NTP: NTP time synchronization is enabled.
NOTE: Setting this register to YES, SNTP or NTP causes the meter to ignore all
other time synchronization sources.

I encounter this issue three weeks ago.

You definitely need to access some type of internet NTP server like pool.ntp.org but you also need to ensure that the NTP port (port 123) is not being blocked between the meter and the internet.  The DNS settings look correct, but the ETH1 NTP Server needs to be set to an internet NTP address like pool.ntp.org.
