ICS T8123 TMR Processor Interface Adapter

The Trusted Processor Interface Adapter T812x is designed to be connected directly to the rear of a Trusted TMR Processor position in a Trusted Controller Chassis T8100. The Adapter provides a communications connection interface between the Trusted TMR Processor and remote systems. The Adapter also provides the option of connecting IRIG-B time synchronisation signals to the Processor. Connection between the Adapter and the Trusted TMR Processor is via two 48-way DIN41612 E-type connectors (SK1), one each for connection to the Active and Standby Processors.

• 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.

 The Adapter should be fitted on the rear of the chassis behind the Processor slots, as shown. The two connectors should fit into the third and sixth slots from the right, where the Processor connectors will fit. In the correct position, two empty slots will be visible on the right. Insert the Adapter into position about 5 mm lower than its final position, and ensure it is slotted in on both sides. Raise the Adapter upwards until the retaining clips click into place.

The following table lists the variants of the Trusted Processor Adapter Unit and the Trusted TMR Processor options that can be made available by using them. All the variants below will enable the use of Dual ('enhanced') Peer to Peer with other Trusted Systems, using the dxpnc40 I/O definition and its associated data transfer I/O definitions.
