Trend (Pen Configuration)
Use a tag placeholder to mark where you want to insert a tag name at runtime. A tag placeholder is a cross-hatch character (#) followed by a number from 1 to 500. Tag placeholders let you create one display that you can use to represent a number of similar operations. At runtime you supply the tag names associated with the particular operation and these are used in place of the tag placeholders. You can also use the Tag Substitution menu option to replace tag placeholders.
To provide tag names at runtime:
Run a parameter file that lists the tag names in the order they are to be used.
or List the tag names in the command line when you give the display command.
For example, to run a display called Canning that has three tag placeholders, with the tags Pea_Weight, Pea_Level and Pea_Temp, you would type in the command line:
Display Canning /TPea_Weight,Pea_Level,Pea_Temp
Tag placeholders can also use folder names. For example, if there are two folders named Peas and Carrots, the graphic could contain the placeholders:
#1\Weight, #1\Level and #1\Temp
At runtime you can use Canning for Peas or Carrots by giving the command:
Display Canning /TPeas
or
Display Canning /TCarrots
