A production method of an input/output device is provided, including a cable connecting step of connecting a cable to be connected to a field device disposed outside a casing main body to a terminal block in a state where the terminal block is housed in the casing main body having an opening portion, an electronic device attaching step of attaching an electronic device to the casing main body by housing the electronic device having a connector portion, which the terminal block can be attached to and detached from, in the casing main body through the opening portion, a terminal block attaching step of attaching the terminal block to the connector portion, and a closing step of closing the opening portion of the casing main body by an opening/closing member.

Production method of input/output device, and input/output device

A duplex control device includes: two systems of duplex controllers and a switching device. The switching device includes, in a feedback path of each system, a transmitter configured to generate feedback data including data for fixing failure detection and a receiving device configured to determine the presence or absence of a fixing failure based on the feedback data output from the transmitter.

Duplex control device and duplex system

A sending part sends a data generated by a second device from the second device to a first device. A data collating part collates the data sent from the sending part with a data generated by the first device, and determines that it is abnormal when a mismatch between these data occurs. Thus, a data generated by the first device is collated with a data generated by the second device and when a mismatch between these data occurs, it is determined that it is abnormal, so that abnormality can be detected surely.
