摘要： PURPOSE:To enable on-line maintenance of the main body of control unit, by enabling the removal of module without disconnecting the power supply, in the functional module provided removably with the control unit main body sectioned by functions. CONSTITUTION:The connector socket 2 is provided in the control unit main body 1, the terminal 2a of the socket 2 is connected to the power supply, and the power supply loop 10 is connected between the terminals 2b and 2n. For the functional module 3 having the connector plug 4 corresponding to the socket 2, the terminals 5a...5n are provided, and the power supply terminals 5a, 5n at the both ends are formed short than the terminals 5b...5m. Thus, the confirmation of the removal of the functional module, its detection, and prevention of output of the external output signal, and missignal due to block release of the operation module can be made. As a result, the removal of module is made possible without interrupting the power supply, allowing the on-line maintenance of the main body 1.

摘要： PURPOSE:To perform the memory storage, by providing a plurality of connector pins at one end of the printed board, providing the card removal detecting circuit and power supply monitor circuit, and preventing the malfunction of the function module even at card removal and power failure. CONSTITUTION:The card 200 is formed every one control block of the printed board 1, and a plurality of connector pins 2a-2q are provided with a given interval on one end of the board 1, and the card removal detecting circuit 8 is connected among the pins 2a-2m. On the other hand, the power supply monitor circuit 9 always monitors the lowering in the power supply voltage fed to the card 200 provided with the board 1 and power supply voltage drop due to the card removal itself. Further, when the power failure signal 10 is at low potential, the outputs of the AND circuits 171, 172 are made low to prevent the production of malfunction. Thus, at the removal of card, and power failure, the malfunction of the function module can be prevented for memory storage.
