Date/Time tab

This tab is used to view or change the current date, time, and NTP synchronization information.

The controller's time zone, NTP server address, NTP synchronization configuration, and the date and time can be manually changed.

Date/Time and NTP Status

The information in this area updates every 30 seconds or when a setting is changed using the Date/Time tab.

This area is read-only.

Information Field

Description

Date/Time

This is the local date and time as reported by the controller.

Time Zone

This is the time zone used by the controller.

NTP Synchronization

This is the synchronization status for the NTP service.

The synchronization is defined in two parts.

  • The first part of the status reports:
    • Active if the controller is configured to synchronize its time with an NTP server.
    • Disabled if the controller is not configured to synchronize its time with an NTP server.
  • The second part of the status reports:
    • Synchronized if the controller is synchronized to an NTP server.
    • Not Synchronized if the controller is not synchronized to an NTP server.

  • The controller stays synchronized for several minutes after disabling NTP synchronization.
    A Disabled, Synchronized status is possible.

Update Date/Time

Click in the Date/Time field to open the Date/Time picker.

Select a new date and time and click OK.

Figure 2: Date/Time Picker

Button

Description

OK

Click to load the date and time selected in the Date/Time picker onto the controller.

Cancel

Click to close the Date/Time picker without changing the date/time on the controller.

Load Host Date/Time

Click to copy the date/time from the host (i.e., computer or device running the web browser) onto the controller.


  • The Date/Time picker is disabled if the controller is configured to synchronize the date/time with an NTP server or if not logged into the controller.

Network Time Protocol (NTP)

This area is used to update the NTP settings.

Setting

Description

Synchronize Date/Time with Server

Changing the state of the checkbox immediately changes the configuration on the controller.

  • A checked box indicates that an NTP server is used to update the date and time.
  • An unchecked box indicates the controller does not synchronize its time or date with an external server.

NTP Server

This is the address of an NTP server to use for synchronizing the date and time.

  • If the controller does not have access to the internet, it is still possible to connect to a local NTP server if the local intranet has an NTP server configured.
    • A local NTP server can be useful for manufacturing areas that do not want to connect controllers and other equipment to the internet for security reasons but still want to keep all computer's and controller's date and time synchronized for data collection purposes.

Update NTP Server button

Click the Update NTP button to apply the new NTP server address.


  • The Update NTP button is disabled if not logged into the controller.

Correct an A05 Alarm


  • If NTP is disabled, and the battery is either not installed or dead on power-up, then the system time is wrong and an A05 alarm is generated.

To prevent an A05 alarm on startup, either:

  1. Remove power from the controller.
  2. Insert a new battery.
  3. Power on the controller.
    There will likely still be an A05 alarm.
  4. Use the Update Date/Time procedure to set the system time.
  5. Power off the controller and wait at least 10 seconds before powering it back on.
  6. Verify:
  • The A05 alarm does not occur.
  • The time is correct on the web page.

Set Time Zone

This area is used to update the time zone used by the controller.

To set the controller’s time zone, select a new time zone from the drop-down box and click the Update Time Zone button.

Time zones are often specified by the largest city in that time zone.

Example: The US Eastern Time Zone is specified by America/New_York.
Typing the first two or three characters of a city or region name filters the list to easily locate a specific time zone.
For New York, typing ne reduces the time zone list to two entries.


  • The Update Time Zone button is disabled if not logged into the controller using the Web server.
