About the Tag Editor

Tags are stored in the tag database associated with a Logix Designer project. Use the
Tag Editor
 to create and manage tags.
TIP: To open the Tag Editor, select
Logic > Edit Tags
.
Access the
Tag Editor
 from the
Edit Tags
 tab in these windows:
  • Controller Tags
  • Parameters and Local Tags
     (when working with Program tags,
    Equipment Phase
     tags,
    Equipment Sequence
     tags, or Add-On Instruction tags)
Use the
Tag Editor
 tab to:
  • Create a new tag or parameter.
  • Delete an existing tag or parameter.
  • Modify tag or parameter attributes (for example, Name, Alias for, Produce a Tag, Display Style, Data Type, and Description).
  • Filter existing tags or parameters.
    TIP: A tag is not case sensitive. For example, FLT and flt are recognized as the same element. However, the tag display always matches the element as shown in the tag database. For example, if AutoMode is the tag shown in the database, typing automode on a bit is recognized as the same element. Once accepted, the tag displays as AutoMode, matching the database.
  • Add a tag-based alarm for a tag.
  • See the number of alarms created for each tag.
  • Open the alarm list for a tag.
  • Choose millisecond or nanosecond precision for time stamps for LINT data type tags:
    • Select
      Date/Time
       to display the time stamp and tag value as date and time with millisecond precision. This is an example of this style:
      DT#2014-05-28-19:00:01.200_000 (UTC-05:00)
      The supported date range is January 01, 1970 to December 31, 2250.
    • Select
      Date/Time (ns)
       to display the time stamp and tag value as date and time with nanosecond precision. This is an example of this style:
      LDT#2014-05-28-19:00:01.200_000_000 (UTC-05:00)
      The supported date range is January 01, 1970 to December 31, 2250.
      TIP: A tag is not case sensitive. For example, FLT and flt are recognized as the same element. However, the tag display always matches the element as shown in the tag database. For example, if AutoMode is the tag shown in the database, typing automode on a bit is recognized as the same element. Once accepted, the tag displays as AutoMode, matching the database.
