Problems solved by technology

However, in general applications that do not require special functional units, the connection board connected to the CPU board, the flat cable, the intermediary board connected to the connection board, and the connector are unnecessary devices, and the existing basic unit will become a surplus. Disadvantages of large, expensive installations of components
In addition, even if the short-distance serial communication in the control device is not used by the special function unit, it is necessary to replace the relay board with a relay communication board, which has the problems of poor operability and waste due to discarding the relay board

Abstract

The invention relates to a unit programmable logic controller which relieves the load of a basic unit and is connected to a multifunctional expanding unit. A plurality of expanding units (400) are orderly connected backwards in a medium unit (300) having a frame part (310) and a bridge part (320) and are arranged on left end of a basic unit (100A) having a CPU substrate (110A) inside, wherein an adapter connector (111a) arranged on the CPU substrate (110A) is connected to a second adapter as a limited specification of the expanding units (400) or a first preceding connector and a second preceding connector arranged at the bridge part (320); the first preceding connector (322) is connected to the expanding units (400) through a backwards connector (312) hidden in the frame part (310); and the first adaptor is superposed on the second preceding connector (323).

Description

technical field [0001] The present invention relates to a unit-shaped programmable controller without a motherboard. In addition to connecting a basic unit with a built-in microprocessor and an input-output extension unit connected to the basic unit, the unit-shaped programmable controller also has a mixed Connect expansion units with various functions. Background technique [0002] Built-in microprocessor, corresponding to the operating state of the input signal of the operation switch and various sensors, and the sequence program stored in the program memory, it is a unit-shaped programmable unit that performs drive control of various actuators and electrical loads such as display devices. In the controller, in addition to corresponding to the normal on / off input and output control, in order to correspond to various applications that require special functions such as input and output of analog signals, input and output of serial signals for communication, or input and outp...
