CP351

1.2 Board Introduction

1.3 Product Overview

The CP351 is an intelligent PROFIBUS controller board providing PROFIBUS FMS
master/slave and PROFIBUS functionality with high communication speeds. The
PROFIBUS protocol FMS is particularly well suited for general purpose communication
at cell or field level, while DP is designed for time-critical communication between sys-
tems and distributed peripherals.
To exchange data between the Motorola M68360 host CPU and the CPU bus, a CPU-
to-PCI processor bridge, an SRAM interface architecture and an interrupt mechanism
are realized.
