ABB 57520001-FE DSTC 408 semiconductor card

The Trusted CI provides the Trusted System with an intelligent Communications Interface, acting as a relay between the Processor, other Trusted Systems, the Engineering Workstation and third-party equipment.

The module has a Motorola Power PC Processor. Bootstrap software is stored on Erasable Programmable Read Only Memory (EPROM). Operational firmware is stored in flash memory and may be upgraded via the Front Panel Port. The Trusted Operating System is used on both the TMR Processor and CI. The real time kernel is a high speed, high functionality kernel made for fault tolerant distributed systems. The kernel provides basic services (such as memory management) and interference free software environments.

A module watchdog monitors processor

 operation and the power supply unit (PSU) output voltages. The module is supplied with a dual redundant +24 Vdc power feed from the chassis backplane. An on-board power supply unit provides voltage conversion, supply conditioning and protection. The Trusted CI communicates with the Trusted TMR Processor via the triplicated InterModule Bus. When polled by the Trusted TMR Processor, the module’s bus interface votes the data 2 out of 3 (2oo3) from the Inter-Module Bus and transmits back its reply via all three Inter-Module Bus channels. The remainder of the Communications Interface is simplex. All communications transceivers are electrically isolated from each other and the module and have additional transient protection measures. The module internal supplies are isolated from the dual 24 Vdc feeds

Communications 

Ethernet Media Access Control (MAC) address configuration is held by the CI as part of its configuration information. Other information regarding port and protocol configuration is obtained from the TMR Processor, as part of the System.INI file. Data is transferred between the TMR Processor and the Communications Interfaces using a common interface called the Network Variable Manager. When data is read from a Trusted System, the data is obtained from the local copy maintained on the Communications Interface, providing a fast response.
