Circuit Board
The circuit board features state-of-the-art circuitry. On the
board are nonvolatile random access memory (NVRAM), random
access memory (RAM), read only memory (ROM), a microproces-
sor running at 16 megahertz, direct memory access (DMA) cir-
cuits, Elsag Bailey custom bus circuits and various support
circuitry. The board attaches to the faceplate with two screws.
The module assembly occupies one slot in a module mounting
unit.
HARDWARE APPLICATION
The multifunction processor module is ideally suited for appli-
cations requiring multiple loop control and module I/O. Since
it handles both analog and digital signals, the MFP module fits
into virtually any control scheme.
FEATURES
The MFP module has the following features:
•
A high speed redundancy link.
•
A serial communication port for station support.
•
Two general purpose serial channels.
•
Direct memory access circuitry.
•
512 kilobytes of RAM memory.
•
256 kilobytes of NVRAM memory.
