Abstract

This article describes a tool control system in which a number of cards required for the control of a factory machine are controlled by a personal computer (PC) through a parallel computer. This configuration enhances control ability and enables a PC to control a large-scale and complicated industrial machine including various devices such as sensors, motors, switches and solenoids.

Parallel Tool Control System

      This article describes a tool control system in which a
number of cards required for the control of a factory machine are
controlled by a personal computer (PC) through a parallel computer.
This configuration enhances control ability and enables a PC to
control a large-scale and complicated industrial machine including
various devices such as sensors, motors, switches and solenoids.

      In the figure, the system includes a PC, an interface card and
a control card.  The interface card contains a high speed
serial-parallel bilateral converter and is set in a PC slot.  The
control card is connected to the interface card through a high speed
serial link.  The control card has a parallel processor and is set in
an extension standard bus (STD-BUS) slot.  Many kinds of STD-BUS
cards required for the control of the machine, such as data I/O card
and motor control card, are connected to the STD-BUS.  The parallel
processor performs control functions for the STD-BUS cards, including
conversion of processor signals to STD-BUS signals.  Any suitable
commercially available parallel processor can be used for this
purpose.  The programs which control the STD-BUS cards are loaded in
a memory on the control card by the PC through the interface card.
The use of the parallel processor permits multiprocessing and
facilitates programming.  It will be possible to cause programs which
control some devices to communicate with other programs to...
