3.8. Communication Busses
3.8.1. Expander Bus
Each 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 TM TMR Expander Processor slot
position to the Trusted TM 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.
