Abstract
PURPOSE:To simply connect a PLC, a numerical control (NC) device and a programming device and to instantaneously switch the connection by switching also system software of the programming device simultaneously with the switching of the connection of the PLC, the NC device and the programming device. CONSTITUTION:A connection switching signal for the programming device is outputted from a contact 29 by a change-over switch 28 and transmitted to a switching circuit 10 through a cable 12. An I/O control part 24 in the programming device is connected to an objective device PLC1 or the NC device 2 with a cable 15. Since a contact 30 is also driven interlocking with the contact 29 at the time of operating the switch 28, an objective system software 25 or 26 is connected to the I/O control device 24. Consequently, the switching of connection can be executed simultaneously with the switching of a system software.
