Use of a Voice Communications Adapter As a Flexible Communications Method

       This article describes a technique by which a personal
computer (PC)- based automation controller can communicate in a
flexible manner with remote personnel or machines.

      Automation equipment is typically controlled by industrial
computers.  These PC-based systems provide an easy, flexible,
strategic, as well as common, programming and hardware architectural
environment.  The voice communications adapter is a card for the PC
that allows the PC to recognize or synthesize the human voice as well
as controlling a telephone line and acting as a modem.

      Before a tool is shipped from a plant, it is usually operated
for a period of time to produce and eliminate any early life
failures.  In order to meet expected production schedules it is
necessary to consider running the tools unattended.  The problem,
however, is the possibility of soft failures that could disrupt the
process early.  In response to this particular problem, the
controller is provided with subroutines that enable the program to
select personnel names and numbers from a file, and dial that number
in an effort to locate and convey the current error status of the
machine.

      The voice communications adapter disclosed herein provides for
the control and monitoring of a telephone extension.  Among the
functions that are provided is the ability to take the handset off
hook, identify a dial tone, dial a...
