Title: Improvements in Apparatus for a Method of Diagnostic Testing of Electrically Controlled Machinery
IPC: G05B19/042
Filed: 1979-12-21
Abstract: In a method and apparatus for testing electrically or electromechanically controlled machinery, a plurality of input signals representative of the operative states of preselected parts of the machinery, and provided at an input (32) are received and stored in a predetermined order in a first storage means (42). Data signals representative of the required values of said input signals are stored in a second storage means (44). The data from the respective stores (42 and 44) is compared in a predetermined sequence by means of a microprocessor operating according to a predetermined program contained within a program store (40). In the event of a mismatch between the compared data signals, the relevant data signals which have been received from the signal input (32) are caused to be read from the relevant store (42) and displayed on a visual display (50). A further display (52) indicates the particular comparison step at which a mismatch was found, and thus enables identification of the relevant part of the machinery from which the input signals were received. <IMAGE>
