Access the Last 10 Values of a Tag

About this task

This topic describes how to access the last 10 values of a tag up to the current time. The difference in the timestamp of consecutive values depends on the time resolution of the tag. For example, if the time resolution is seconds, the timestamp of consecutive values of the tag will be one second apart.
Note: If a tag name contains a comma or a semicolon, you cannot view the last 10 values of the tag.

Procedure

  1. Access Configuration Hub.
  2. If you want to access all tags, in the NAVIGATION section, select Tags.
    A list of all the tags appears.
  3. If you want to narrow down the search results, select Search.

    Enter the search criteria, and then select Search. You can add more attributes by selecting Add Attribute. You can enter a name or a value partially or use the wildcard character asterisk (*).
    The list of tags are filtered based on the search criteria.
  4. If you want to access the last 10 values of a single tag, right-click the tag (or select ), and then select View Last 10 Values.

    If you want to access the last 10 values of multiple tags, select the check boxes corresponding to the tags, right-click (or select ), and then select Trend. You can select up to 10 tags.
    The last 10 values of the tag appear, along with the timestamp and quality of each value. You can switch between the trend view and the table view. In addition:
    • For an array tag, all the values in the array appear for each timestamp.
    • For a tag using an enumerated set, values of all the states appear for each timestamp.
    • For a tag using a user-defined data type (UDT), values for all the fields appear for each timestamp.
    Tip: You can also filter the values by changing the duration, sampling type, time interval, and so on by selecting .
