MODCOMP Announces MODACS/X Open System Upgrade Solutions for MODACS PIO Subsystems

July 29, 1997, Ft. Lauderdale, Florida - MODCOMP announces the release of its open system upgrade solution for its 1800 Series MODACS(TM) Process I/O Subsystems. Using the VME-based Intel® Pentium® processor, the REAL/IX PX(TM) operating system ­ MODCOMP's real-time implementation of the UNIX® System V operating system ­ and the MODACS/X(TM) Process I/O Controller, provide an easy migration to industry standard open systems technology.

The heart of the upgrade is a four-slot VME chassis taking the place of the existing MODACS controller card file, and an integrated power subsystem that is plug compatible with the existing MODACS power subsystem components. The single-width 6U form factor MODACS/X controller interfaces the MODACS PIO bus with the VME bus. This controls up to six PIO cardfiles. A high performance VME-based Pentium processor manages and provides communication to and from the MODACS Subsystem in the network. The processor, under the control of MODCOMP's REAL/IX PX real-time operating system, also manages the subsystem's operation. It can perform much of the front-end processing such as scan table management, engineering conversion, PID control, etc. As a fully self-reliant CPU, the subsystem is also capable of independent operation if it loses communication with the supervisory/server CPU.

"Preserving our customer's investment in their systems, while providing an easy transition to open systems technologies, is our prime responsibility," said John P. Clary, MODCOMP president.
