3.8. Communication Busses

3.8.1. Expander Bus

ach TMR Expander Processor Module contains a Bus Interface, isolation components and

transceivers to the Expander Bus. The triplicated Expander Bus provides communication

interconnection between the TMR Processor Chassis and the Expander Chassis at a data transfer rate

of 1.5Gbps via UTP cables.

3.8.2. Inter-Module Bus

Each TMR Expander Processor Module FCR contains a Bus Interface to the Inter-Module Bus. The

triplicated Inter-Module Bus provides communication interconnection between modules in the TMR

Expander Chassis, at a data transfer rate of up to 12.5Mbps.

The Inter-Module Bus handles the following triplicated signals:

Data

8-bit, bi-directional bus.

Control

Bus clocks, module enables and bus direction control.

System Watchdog

System Watchdog signal to the I/O modules.

Power Fail

System power fail warning to I/O modules.

Slot

Indicating the left or right Trusted

TMR Expander Processor slot

position to the Trusted

TMR Processor.

Chassis ID

a 4-bit code indicating the chassis number or id.

3.9. Module Configuration

The Expander Processor requires no configuration to the module itself. The module provides status

information that available to the application programmer. The IEC1131 TOOLSET provides the

interface to configure and use this status information.
