Create integer and real tags

You can specify integer and real tags to show numerical values of processes running in an InTouch application.

The following steps show how to define memory and I/O integer and real tags. Memory integer and real tags must be assigned an initial value. You also must set minimum and maximum data ranges.

For information about setting the I/O properties of an I/O integer and real tags, see Specify integer and real I/O tags.

Important: InTouch real numbers are limited to eight-digit precision. To avoid possible rounding errors, do not exceed eight-digit precision when you specify the properties of your real tags. For more information, see IEEE decimal units.

Define memory integer and real tag values

1. Assign memory integer or memory real as the type of tag in the Tag Types dialog box. The detail portion of the Tagname Dictionary dialog box appears.

   

2. Set the properties for integer and real tags. Do the following:

   • In the Initial Value box, type the integer or real number associated with the tag when the application starts.

   • In the Min Value box, type the minimum integer or real number for the tag.

     The Min Value sets the minimum possible value for numbers associated with memory integer and real tags.

   • In the Max Value box, type the maximum integer or real number for the tag.

     The Max Value sets the maximum possible value for numbers associated with memory integer and real tags.

   • In the Eng Units box, type the label you want to use for the tag's engineering units.

3. Save your changes to the tag.
