A system for integrating a software programmable logic controller
functions along with the human machine interface functions for plastics
molding machines is disclosed. A general purpose computer integrates the
programmable logic controller functions of monitoring and controlling
input output devices and sensors along with the human machine interface
functions of monitoring and presenting the status of the plastics molding
to an operator. Through this system, primarily the data latency exhibited
between the human machine interface and the programmable logic controller
are eliminated, along with the cost of maintenance and upgrade of the
machine.
