インＬ１を介し上位計算機１に伝送することができる。The input/output device 2 sequentially receives a plurality of input signals by an input switching means 21, amplifies and digitizes them by an input circuit 22, and processes linear rice or the like according to each input signal by a processing means 23 such as a micro combi coater. Processing is performed and these measurement data are stored in memory 24. The data in the memory 24 can be displayed on the display means 26 by the operation means 25, and can be transmitted to the host computer 1 via the communication means 27, the conversion means 28, and the transmission line L1.
逆に上位計算機１から入出力装置２の動作の制御を行う
ことができる。Conversely, the operation of the input/output device 2 can be controlled from the host computer 1.

の開閉制御を行う。The host computer 1 sets only the input of a specific channel among all the channels of the input/output device 2, and prevents unnecessary channels from being input. In other words, the processing means 23 of the input/output device 2 stores the upper weight 1 in the memory 24.
The input channel data set in , for example, is stored, and switching means such as a relay of the input switching means 21 is controlled to open and close so that only the data of channels 1, 3, 5, 6, and 7 are taken in, for example.
