PROBLEM TO BE SOLVED: To provide a logical control unit of which a back plane is directly mounted on the DIN rail, and an integral type device module used for this control unit. SOLUTION: The control unit 2 is composed of the integral device modules 8, 10, 12 and 14 which are plugged into the DIN rail 4 and the back plane 6 provided with the DIN rail 4. The above modules contain a power unit, a logical control member, an input-output unit and various types of members such as a gateway or the like. Each input-output unit is provided with a microprocessor member. In addition, the above modules are provided with a fully slidable mounting arrangement, which is made to move so as to be adjacent to the flexible tabs which engage with the DIN rail 4 thus preventing the deflection of tabs and sampling the above modules from the DIN rail 4 are made possible.
