DESCRIPTION


Trusted

TM

TMR Processors contain and

execute the operating and application software
programs in a triple redundant, fault tolerant
controller system..

The fault tolerant design contains six fault
containment regions. The three synchronized
processor fault containment regions each
contain a 600 series microprocessor, its
memory, voter, and associated circuits.

The non-volatile memory is used to store the
configuration and application programs for the
system.

Each processor has an independent
power supply fed from the dual-
redundant 24Vdc power supply of the
Trusted

TM

Controller chassis backplane.

The processor power supplies provide
short circuit protection and regulated
power to the module electronics.

The processors operate concurrently to
achieve triple modular redundancy and
fault tolerance. By providing 2-out-of-3
hardware voting on every inter-
processor exchange and memory data
retrieval, uncompromised fault detection
and error-free operation are assured.

TMR

Processors

communicate with other modules via a
backplane mounted, triplicated Inter-
Module Bus. Additionally, interface
modules

are

used

to

support

communication with I/O sub-systems
and other equipment.

Module

faults

are

automatically

detected, time-stamped, and stored for
historical review. Transient faults, once
they

are

recorded,

are

cleared

automatically without nuisance alarming.
Permanent faults in a processor are
annunciated on the front panel of the
module, without disturbing on-going
processing in the two remaining
processors.

When

a

failed

Trusted

TM

TMR

Processor is replaced, the replacement
module is automatically initialized
without external loaders or other
equipment.

Application programs are developed
using the full suite of IEC 1131-3
languages. The user can load, run,
stop,

single-step

or

delete

the

application program. A front panel
maintenance enable keyswitch allows
the download of application programs.
