Abstract
A programmable-controller remote terminal apparatus of the invention shortens a system down time generated in replacing an I/O unit, in the I/O unit having a three-divided configuration of a remote terminal apparatus in which miniaturization and low-profile are developed. A programmable-controller remote terminal apparatus, which is connected to a programmable controller through a fieldbus, includes a communication unit and at least one I/O unit which can communicate with the communication unit through a serial bus line, wherein the communication unit has a device which obtains unit information for identifying each connected I/O unit and setting value information set in each I/O unit, and the communication unit has a backup device which can store the obtained unit information and setting value information of each I/O unit in a storage medium included in the communication unit.
