This document provides general information for the Trusted® Processor Interface Adapter T812X.
The Adapter provides easy access to the communications ports of the Trusted Triple Modular Redundant (TMR) Processor (T8110B & T8111) in the Controller Chassis for the Distributed Control
System (DCS) and other links. The unit is also used to enable a number of extended facilities available on the Trusted TMR Processor including facilities for the reception of IRIG-B time synchronisation signals, enabling the use of Dual (‘enhanced’) Peer to Peer and enabling the
Trusted System to become MODBUS Master.
Features:
• Allows easy access for external systems to communicate with a Trusted TMR Processor.
• Easy installation (connects directly to the rear of the Controller Chassis).
• Two RS422/485 configurable 2 or 4 wire connections.
• One RS422/485 2 wire connection.
• Fault/fail connections for Active and Standby Processors.
• Processor diagnostics connection.
• PSU shutdown monitor connections.
• Option for connecting IRIG-B122 and IRIG-B002 time synchronisation signals.
• Option to enable MODBUS Master on the Trusted Communications Interface.
