PURPOSE:To suppress an abnormal data transmission due to a setting miss or a hardwear trouble by providing a monitoring circuit at a final output terminal in a one-way information transmitter. CONSTITUTION:Parallel data are outputted from an inputting part 1 to a basic processing part 2, converted into serial data in a prescribed form, and outputted from a data transmission processing part 3. The output data are checked by a data content check circuit 5, data sequence check circuit 6, and data amount check circuit 7, and the presence or absence of the abnormality of the data is discriminated by a discriminating part 8 based on each check content. When the abnormality is generated, an alarm bit is added to the output data, and the data in the previous cycle are outputted from a memory part 4. |
