Operation for each action of a machine is individually controlled by providing a file of set of components necessary to carry out the operation and a file of a set of components that are available and then determining in sequence whether each required component is also available and transferring those components that are both required and available in sequence to a fault file. The fault file may then be read in sequence and used to control the action being controlled so that if anyone of the required components is not available, the fault file so indicates and terminates the operation based on the first component found to be inoperative so that it is an easy matter to define the source of the problem. |
