Rockwell Automation 57C435 Processor Module, AutoMax - Manual (Page 7)

1.0 INTRODUCTION
The products described in this instruction manual are manufactured
by Reliance Electric Industrial Company. The Automax Processor
moduleplugs into thebackplaneof an AutoMax rack and executes
application programs which in turn control other AutoMax modules in
the system. The M/N 57C430A and 57C431 Processor modules are
based on the Motorola 68010 16Ćbit microprocessor. The M/N
57C435 Processor module is based on the Motorola 68020 32Ćbit
microprocessor. All three Processors are programmed using three
highĆlevel application languages: BASIC, Control Block and Ladder
Logic.
The Processor modules have the following memory/speed
configurations:
Model CPU Speed Memory
M/N 57C430A AutoMax
6010 Processor module
8 mHz 256K Parity RAM
M/N 57C431 AutoMax
6011 Processor module
8 mHz 512K Parity RAM
M/N 57C435 AutoMax
7010 Processor module
25 mHz 512K Parity RAM
Up to four AutoMax Processor modules can be used in a rack
(M/N 57C331, M/N 57C332 or M/N 57C334) to increase the
processing capability and the total memory available for application
tasks. M/N 57C430A, 57C431, and 57C435 Processors can be used
in thesamerack. M/N 57C430A Processors make135KĆ150K
available for application programs depending on which operating
system is loaded onto the Processor. M/N 57C431 and 57C435
Processors make 300K available for application programs, regardless
of which operating system is loaded onto the Processor. Multiple
Processors in a rack require the use of the Common Memory module
(M/N 57C413 or M/N 57C423) for bus arbitration and sharing of
systemĆwideinformation. TheCommon Memory modulecan also be
used with a singleProcessor moduleto makeavailablean additional
128K bytes of memory for common, i.e., systemĆwide, variables.
An onĆboard lithium battery and a superĆcapacitor protect the
Processor module from power failures. Should the system lose
power, the onĆboard battery of the M/N 57C430A or 57C431
Processor can maintain the contents of RAM for a minimum of 42
days. Theonboard battery of theM/N 57C435 Processor can
maintain thecontents of RAM for a minimum of 186 days.
The remainder of this manual describes the functions and
specifications of the module. It also includes a detailed overview of
installation and servicing procedures.
