Quick Help

This template based set of calculations provides a means of programming for very simple operations such as logically ANDing or ORing a couple of binary objects to produce a result to be sent out to another object. Select the operation to be performed from the drop list. All but logical NOT operations require two operands. Enter object numbers as applicable.

Some operations are valid for ranges of objects. Select "and" or "thru" to select two objects or multiple objects in a range. Average, sum, and logic operations are valid for ranges of multiple objects (of same type).

Delete will remove the rule number shown in the "Showing" box. Insert will insert a new rule before the rule number shown, and is used for placing rules between existing rules. It is not necessary to use Insert to add rules to the bottom of the list or to define any rule presently having "none" for an operation (unused rule).

Error checking will prevent entry of an invalid object in the rule. However, if a previously valid rule is invalidated by that object being later deleted, the now invalid rule will prevent other updates. Because error trapping happens sooner than the insert/delete process, the delete will not remove the invalid rule. To get around this problem, enter zero for object number, update, then delete (or enter a new valid object number if you intend to keep the rule).

Selecting "none" as the operation effectively deletes the rule even though it will still appear in the list until deleted. Unused rules at the end of the list will always show "none" as the operation. If you wish to prevent these from being displayed, reduce the number of rules enabled.

The number of rules enabled simply limits the scope of rule review so that you do not have to review a lot of unused rules.
