I have a BRX PLC behind a StrideLink VPN device. Once per week, I would like the PLC to enable the VPN device (allow outside connection) and use the NETTIME instruction to retrieve the current time and date from the NTP server at 0.pool.ntp.org I 've got the logic in the PLC set to enable the VPN device every Sunday morning between 2:00:00 and 2:00:59. At 2:00:00 + (20) seconds, the PLC triggers the NETTIME instruction.

What, if anything, do I need to do with the StrideLink VPN device to allow this to work? Does StrideLink have a NPT server I can use, or will any NTP server work?

Thanks,

Don't know if it is relevant to your effort, but Do-more uses SNTP, not NTP. Don't remember what the major differences are, but ports should be different.

Does this mean that the following quote from the Help file for NETTIME is incorrect?

"This instruction can use either an NTP Server or an SNTP Server as the time server. "

No, it's right. NTP servers also support SNTP.

I thought the ports were different, but I misremembered. Been doing this too long...everything blurs together. Disregard.
