Abstract

PURPOSE:To improve the working efficiency of a connection switch device by switching the connection among a programmable logic controller PLC, a numerical controller and a programming controller after switching a switch circuit via a changeover switch. CONSTITUTION:When a changeover switch 11 of a control panel 5 set at a remote place from a composite controller 3 is operated, the operating states of the switch 11 are transmitted to the control input terminals of switching elements 16 and 17 via inverters 18 and 19. Therefore, it is possible to set one of two elements 16 and 17 set in a switch device 10 at a low impedance with the other element set at a high impedance respectively with operation of the switch 11. For instance, the input terminal of an inverter 18 is grounded in case the element 16 set between a PLC 1 and a programming device 4 is set at a low impedance. Then the device 4 is connected to the PLC 1 after the element is set at a low impedance and signals are transmitted and received. While the element 17 is set at a low impedance when the switch 11 is switched adversely. Then the device 4 can be connected with a numerical controller 2.
