Editing a Decision Block

To edit a Decision block expression, follow these steps:

While in Selection Mode, double-click the Decision block to open the “Decision Block...

Configuration” tab (see Figure 4-6).

Click the “Data Type” drop-down list to select the data item type. Only valid data types

appear in the list. Available types are Flag, Input, Output, Keypad Key, Timer/Counter,

and High-Speed Counter.

Enter the “Data Item” using one of the following techniques:

–

Enter the data item number, for example “1” or “01”. The type is known.

–

Enter the data item ID (“DI”), for example “I-01”. When tabbing to the next field,

nanoNavigator displays the data item name associated with the ID.

–

Use the drop-down button to display the list of data items that correspond to the

selected data item type. The drop-down list only shows data items of the “Type”

selected.

Use the “Condition” drop-down list to set the condition desired.

Click the “OK” button.

Yes/No Path Selection

By default, the connection that goes out the bottom of the Decision block is the “Yes” path;

the exit on the right is the “No” path. The “Decision Block... Comments” tab permits adding

a block comment and swapping the positions of the “Yes” and “No” exit paths (another way

is to right-click a block, then select “Swap Yes/No Connectors” from the pop-up menu).

Entering the block’s cell address (“Grid and Cell Address” on page 3-16) explicitly sets or

modifies the target block of the “Yes” or “No” connector.

When selecting an unconfigured Timer/Counter, a small dialog box appears with a drop-

down list that permits configuration of the Timer/Counter as a “Counter”, “Duration

(HMS)”, or “Duration (mSec)”.

Or use the <Tab> key to highlight the field and use the first character to toggle the value.

For example, typing the letter “o” toggles among values beginning with the letter “o”.

Use the

button on the right side of the conditional expression line to delete (make all

fields blank) the expression.
