DIMENSION PLC

DESCRIPTION

This assembly is a large capacity Programmable Logic Controller ("PLC") which performs all Input/Output, control (ladder) logic, and host communications operations for industrial automation applications.

The DIMENSION™ Programmable Controller ("DPC") provides advanced data measurement, closed-loop control, and local/remote communications for industrial automation systems.

Each DPC features a powerful 32-bit CPU (industrialized IBM compatible) running the Tele-Denken SoftPLC™ kernel, combined with one or more intelligent I/O controllers ("IOCs") that can be "distributed" around the plant. These IOC cardfile(s) are populated with applicable multipoint I/O cards.

These units are backward compatible to Allen-Bradley 5/25 PLCs, supporting existing ladder-logic programs as well as Data Highway communications. Combined with advanced ladder development tools, the DPC also supports external "C" subroutines when required for particular applications.

DPCs are also upward compatible with the Company's "open system" ENTERPRISE™ Station Computer family for long term evolutionary capabilities.

Typical Input/Output: 256DI/PI 128AI 128DO 64AO
