Claims

[Scope of utility model registration request]

A dual analog input system for multiple loops that includes a processor, memory, and a data base containing control loop input/output data, and sends/receives the input/output data of this database to and from the control target in the form of analog signals. An auxiliary control device for a multi-loop control device connected to an output circuit by an internal data bus, the claw-operated device having an analog indicator corresponding to input/output signals of the plural loops and operation keys for an operator. A database that is connected to the internal bus of the controller and multiple loop control device and can hold input/output data for multiple loops, and displays the input/output data for each loop in this database in the form of analog signals. An output conditioner feeds the indicator of the controller, an input conditioner reads the state of the operation keys on the display controller and writes it to the database, and a manual When not in the control state, the content of the data base is made to match the content of the database on the active side of the redundant analog input/output circuit, and when in the manual control state, the content of the database of the redundant analog input/output circuit is made to match the content of the database on the active side of the redundant analog input/output circuit. An auxiliary controller comprising an interface circuit with firmware matching the contents of the data base.
