10Ć1 AutoMax 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 DCS modules in the system. 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
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 backĆup to
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 backĆup. 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). With 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.
