NTP server

The x500 IoT gateway runs a Network Time Protocol (NTP) server, which automatically and periodically syncs its own time with the X4 remote.

The Real Time Clock and NTP server built into the x500 IoT gateway allows the entire machine line connected to the x500 IoT gateway to sync their time, preventing time drift. This guarantees identical internal clocks.

Time zones

NTP does not acknowledge time zones, instead it manages all time information based on UTC. To convert UTC to local time, you’ll need to apply the local time zone in the PLC/HMI itself.

How can I set NTP?

In order to use NTP on your PLC and HMI, perform the following steps:

  • Enter the x500 IoT gateway’s LAN IP address in the NTP settings of the PLC/HMI.
  • If possible, apply the correct time zone in your PLC/HMI’s settings.

NTP and Cloud Logging

Cloud Logging timestamps are based on UTC. After pulling the data from the PLC or HMI, the data is timestamped and pushed to the cloud. Therefore, altering the local time in a PLC/HMI won’t affect Cloud Logging data.
