Abstract

PURPOSE:To carry out simply the logic and operation check of the process control device by carrying out the logic and operation check of either of the processing device and the input and output device based on the memorized input and output data. CONSTITUTION:The buffer memory incorporated in the process input and output control device 9 is disposed between the processing device 8 and the process intput and output device 500 and can be separated from one of two devices. In this instance, the input and output data of the remaining device separated from the other is memorized in the buffer memory. In accordance with the memorized input and output data, the logic and operation check of one device is performed. In this manner, the process control device, especially the logic and operation check of the processing device and the process input and output device can be carried out easily.
