From the SELECT LETTER screen (Figure 21) the tag may also be selected via a code by
pressing the [F5] key.

Via Code

This method of selecting a tag is initiated from the SELECT LETTER screen (Figure 21) by
pressing the [F5] key. It allows you to select the tag, given that you know the tag code associated
with the desired tag. Every parameter and variable (ie. tag) has a unique code associated to
identify it to devices incapable of making decisions based on a name, such as a PLC for example.

Use the data entry keys [0]-[9] to enter the desired code on the SELECT CODE screen (Figure
23). The entered code may be edited using the [backspace] key. Press the [enter] key.

The screen will display one of two formats. If the code you entered was valid, it will show the
name of the tag associated with the code (Figure 24) This allows you to verify that this was the
tag which you intended to select with the code before proceeding. If correct, press the [enter] key.
If incorrect, immediately repeat the process by typing in another code. If the tag code was not
valid, a message indicating such is displayed as in Figure 25.
