The programmable logic controller (PLC) is changing to
reflect the demands of sequencing and continuous processing
applications. The PLC can be thought of as a hardened
computer with high speed I/O and communications ports with
bus interfacing for multiprocessor or coprocessor
enhancements, and a BIOS that supports those features. PLC
manufacturers now retain control over both aspects of the
PLC which interoperate in a proprietary manner. Via the
delineation of the two may come a standard real time
operating system or real time kernel which would give rise
to true applications portability.
