<p>PURPOSE:To simplify a generating work of a sequence data, by constituting so that connecting relation of component parts is substituted for a logical circuit and is logically operated in a logical part, when the connecting relation of the component parts is inputted to the operating part. CONSTITUTION:Connecting relation of component parts in an equivalent circuit of a sequence controlling circuit is inputted to an operating part 20 by use of a prescribed symbol code with an input key. Subsequently, the sequence controlling circuit is simulated by substituting the connecting relation of the component parts for a logical circuit and logically operating it, in the operating part 20. This simulated input becomes an address data, and the simulated output is written in a sequence memory 26. This simulated output written in the memory 26, that is, the sequence data is checked as to whether an error exists or not, in a sequence checking part 29. When there is no error in the sequence data, contents of the memory 26 are written in a P-ROM 28 through a writing circuit 27.</p> |
