• Number of tags

  The maximum number of tags is sum of D2000 objects, which are configured in the particular application. The tags includes the following D2000 objects:

  • User variables
  • I/O tags
  • Eval tags (note: if it is a structured eval tag, the number of rows in the target structure is counted into the number of tags)
  • Remote tags
  • Structured variables (Note: The size of whole structure is included, i.e. number of rows times number of columns, divided by a value of 5 (rows*cols/5),. The columns of "Object" value type, i.e. a reference to other D2000 objects, are not included and fields whose value can not be changed during application run (they do not have an active configuration item Manual control)).
    
    
  More detailed information about the number and structure of the tags can be obtained using the SHOW_CONFIG tell command.
