10Ć1AutoMax Processor Overview

10.0 AutoMax PROCESSOR

OVERVIEW

The AutoMax Processor module plugs into the backplane of an

AutoMax rack and executes application programs which, in turn,

control

other AutoMax or DC

S modules in the system. The Processor

modules have the following memory/speed configurations:

Each Processor contains 32K of EPROM for boardĆlevel diagnostics

and boot software. The operating system, which oversees the

operation of the CPU and the execution of application tasks, is

provided in two versions. The version that includes the Ethernet

functions will occupy approximately 134K of RAM, leaving 122K

available for application tasks on the M/N 57C430A Processor. The

standard operating system will occupy approximately 119K of RAM,

leaving 137K available for application tasks on the M/N 57C430A

Processor

. The M/N 57C431 and M/N 57C435 Processors have 300K

available for application tasks regardless of which operating system

is being used. Both versions of the operating system are included

with the AutoMax Executive software (see section 5.4.3 for loading

the operating system).

Processor

modules come equipped with onĆboard battery back

Ćup

protect against power failures. External battery backĆup is therefore

not required for racks containing a single Processor module. For

racks containing multiple Processor modules, however, external

battery backĆup may be required to protect the Common Memory

module against power failures. If you are using Common Memory

module M/N 57C413 or earlier, external battery backĆup is required.

M/N

57C413B and later have onĆboard battery back

Ćup. Although this

section describes the Processor module in some detail, for more

specific information, refer to instruction manual JĆ3650.

10.1 Single Processor Module in a Rack

A Processor can occupy any slot in the rack from 0Ć4 (refer to figure

10.1). W

ith the standard operating system loaded, a single

M/N 57C430A Processor module in a rack makes available

approximately 137K of memory for application tasks. A single

M/N 57C431 or 57C435 Processor module makes 300K available for

application tasks.
