Description
Core Product Summary
The B&R (Bernecker & Rainer) ECCP70-01 (CP70) is a legacy central processing unit (CPU) module designed for the B&R Multicontrol / MIDI modular industrial automation architecture. Built to coordinate automated machine control tasks, this module serves as a core processing node within rack-based industrial control systems.
The unit features 42 KB of SRAM application memory (supporting roughly 42,000 instructions) and requires a separate PROM for storage. For system communication and programming, the ECCP70-01 is equipped with versatile onboard serial interface connections, including an isolated TTY online port alongside flexible RS-485, RS-232, and TTY communication paths.

Detailed Product Overview
The B&R (Bernecker & Rainer) ECCP70-01 is a mature central processing unit card built for the Multicontrol (CP70) system family. Designed to meet the modular demands of factory automation control, it combines processing execution with flexible multi-standard serial communication links.
The hardware architecture relies on 42 KB of internal SRAM to execute control instructions, requiring a separate PROM to permanently hold user application files. Communication flexibility is provided via integrated RS-485 (electrically isolated for networking), RS-232, and TTY interfaces. Because of its specific hardware profile, the ECCP70-01 is primarily utilized by engineering teams maintaining, servicing, or extending legacy B&R Multicontrol setups.
Applications & System Role
The B&R ECCP70-01 operates as the central processing brain within legacy B&R Multicontrol industrial automation frameworks. Positioned in primary rack slots, it executes control logic programs, coordinates data flow between modular digital/analog I/O cards, and communicates with external operator panels or supervisory stations via its onboard serial options. It is typically found supporting older machinery cells, production lines, and discrete manufacturing equipment utilizing the B&R Multicontrol platform.
