ION 7500 / ION 7600 User’s Guide Time Synchronization: ION or GPS

Time Synchronization: ION or GPS

Use ION software for systems where time synchronization is not critical. ION software can synchronize a meter’s clock to within ± 16ms (typical) of other meters in a serial network.

Use a GPS receiver if you require time synchronization to within ± 1ms of Coordinated Universal Time (UTC), or within ± 2ms (typical) of other meters in the network. If you install a GPS receiver, you’ll need an additional serial network.

ION Time Synchronization

This field is in a Device’s Basic Properties screen for Ethernet devices; you set the Time Synch Ethernet Interval property under Advanced Properties. You configure a serial device via the Direct Site advanced properties.

ION software provides time synchronization by default. (It is disabled by default.) The communications port and protocol used for communications between ION software and the networked devices is automatically used to send time synchronization signals to all connected ION devices. ION software sends out a time sync packet and the time is set once the packet is received.

Time synchronization values are set when sites or Ethernet devices are defined in an ION Enterprise network. You enable time synchronization or set custom intervals for any device in any site through the ION Management Console.

Enabling or Customizing Time Synchronization

1.Launch the ION Management Console.

2.From the System Setup Pane, select Sites or Devices.

Select Sites if you want to customize a particular serial, modem, or Ethernet Gateway site.

Select Devices if you want to customize an individual Ethernet device.

3.Right-click in the main window and select Properties.

4.Right-click inside the display window and select Advanced Properties.

The fields for enabling or customizing time synchronization are shown below.

Use these fields on the Site Ad- vanced Properties screen to enable time synchronization or set custom intervals for any device in any Serial Site or Ethernet Gateway Site.
