Since actions in the Control block execute in the order they appear, Control blocks permit

reordering actions. To reorder an action, select it (it appears highlighted), and then use the

“Move Up” or “Move Down” buttons to move the selected action. For these buttons to be

available, there must be more than one action defined in the block.

Editing a Control block

To edit a Control block’s expression, follow these steps:

Double-click the Control block to open the “Control Block... Configuration” tab (see

Click the “Type” cell, and select the data item type desired.

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

–

Enter the data item name in the “Data Item”

field. While typing, nanoNavigator

attempts to auto-complete the name. When tabbing to the next field,

nanoNavigator displays the data item ID associated with the data item name.

–

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.

From the “Action” drop-down list, select the action desired. The choices available in the

drop-down depend on the data item type selected.

Repeat steps 2. through 4. as required for additional expressions. A block must have at

least one expression. After entering more than one expression, the “Move Up” and

“Move Down” buttons become available. These buttons permit re-ordering the

expression, since the nanoLC executes them in the order they appear in this dialog box.

Select one of the expressions, and then click the desired button to move it in the list.

Click the “OK” button.

The order rarely makes a difference. This feature is primarily to improve readability. It

does, however, make a difference when starting a timer, and then resetting that timer, as

opposed to the inverse. This is applicable if the timer was previously stopped but did not

complete (elapsed time operations).

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

down that permits configuration of the Timer/Counter as a “Counter”, “Duration (HMS)”,

or “Duration (mSec)”.

Use the

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

fields blank) the expression.
