1.0 INTRODUCTION

The products described in this instruction manual are manufactured

by Reliance Electric Industrial Company. The Automax Processor

module plugs into the backplane of 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 the same rack. M/N 57C430A Processors make 135KĆ150K

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

systemĆwide information. The Common Memory module can also be

used with a single Processor module to make available an 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. The onboard battery of the M/N 57C435 Processor can

maintain the contents 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.
