A method and apparatus for passively monitoring the distribution of fuel and lubrication fluids to track vehicles and other heavy duty work equipment, such as bulldozers, draglines, scrapers, loaders, etc. The system includes means for identifying and recording the identity of the dispensing vehicle, the dispensing operator, the location of the dispensing vehicle, the receiving vehicle, the receiving port on the receiving vehicle, the type of fluid dispensed, the quantity of fluid dispensed, and the time of the dispensing. The system also includes means for verifying that the proper fluid is dispensed to the appropriate port. Use of the system does not in any way interfere with the servicing operations.

Method, system and apparatus for passively monitoring the maintenance and distribution of fluid products to heavy work vehicles

A system and process for generating a control program for execution by a programmable logic control unit including the steps of: providing a variable editing user interface allowing a user to define and edit variables including input variables and output variables; providing a program level editing user interface allowing the user to edit a program level; providing a state editing user interface allowing a user to define and edit a plurality of states of the control program; providing a condition editing user interface allowing a user to define and edit at least one condition for each of the states of the control program; and generating the control program as a function of associative relationships of the variables, states, and conditions.

System and method for programming a logic control unit

A process is provided for generating a flow chart representing a control program defined by associative relationships between program levels, states and conditions, each condition specifying a transition from an associated one of the states as a source state to a corresponding selected destination state upon satisfaction of the condition during execution of the control program by the logic control unit. Each program level defines a sub-process of the control program. The process includes the steps of rendering on a chart: a first group of state indicators each representing a corresponding one of a first plurality of the states, and including an associated first state anchor point; a first group of condition indicators each being associated with a corresponding one of the first group of state indicators, each of the first group of condition indicators indicating a corresponding one of a first plurality of the conditions, and including an associated first condition anchor point; a second group of state indicators each indicating a corresponding one of a second plurality of the states, and including an associated second state anchor point; a second group of condition indicators each being associated with a corresponding one of the second group of state indicators, each of the second group of condition indicators indicating a corresponding one of a second plurality of the conditions, and including an associated second condition anchor point; and for each of the conditions, a corresponding transition indicator indicative of transition information specified by the condition.
