A method for searching and eliminating program faults by run of a block modes barrel

摘要

the invention concerns a method for debugging a follow-up programme, on the basis of eingabeinstruktionen, one will be provided to be supplied by a programmable controller is carried out.the program is stored in an intermediate language, the input from a leitersprache or will be provided and a sequential funktionssprache has been translated, and the program using a variety of methods can be fehlerbereinigt.a first method includes execution of einzelinstruktionen, starting with a predetermined word and under execution of a bedienerspezifischen number of instruktionsworten.a second method comprises a schleifenspezifisches procedure in which a startwort followed by a stoppwort are identified, and the number of loops between the two words pass through, while the procedure as long as is until the schleifenzu00e4hlung zero wi rd.a third method comprises a blockmodusdurchlauf, a startwort than at the beginning of the iteration is identified during the end of the iteration, the last word in the block to which the startwort refers. the endwort automatically as a transition between a ausgabeinstruktion and a subsequent eingabeinstruktion identified.the number of words of startwort until the end of the block is calculated, and as a basis for determining the length of blockmodusdurchlaufs used.
