<p>PURPOSE: To faithfully reflect the state change of a process input signal on an output signal by extracting the data on a text from one of both ends to the other of the text and vice versa, overwriting and storing the extracted text data for every identification symbol, and outputting the output signal based on the stored data. CONSTITUTION: A received data search part 31 extracts the received data toward an arrow (b), i.e., toward the start position from the end position of the received data against the text of these data in the first time and then stores the extracted data in a received data storage part 32. At the same time, the part 31 sets a stored flag equivalent to an identification symbol of the part 32 corresponding to the extracted data at 1. Then the data are outputted through a process output control part 22. The received data are extracted and stored toward an arrow (a), i.e., toward the end position from the start position of the text in the second time like the first time after a prescribed time. These stored data are also outputted as the process signals.</p> |
