Invensys Triconex 3008 Main Processor
A Tricon chassis houses three Main Processor Modules, each serving one channel (also referred to as a leg) of the controller. Each processor independently communicates with its I/O subsystem and executes the control program.
The three MP Modules compare data and the control program at regular intervals. Each Main Processor operates autonomously with no shared clocks, power regulators, or circuitry. Processor specifications are listed in the specifications table for each MP.
A high-speed proprietary bus system called TriBus provides these functions: interprocessor communications, hardware majority voting of all digital input data, and comparison of control program variables. TriBus uses a fully isolated, serial communication channel operating at 4 megabits per second. A direct memory access controller manages the synchronization, transfer, voting and data correction independent of the control program or executive software.
DRAM (dynamic random-access memory) is used for control program, sequence-of-events data, I/O data, diagnostics, and communication buffers. SRAM (static random-access memory) is used for the defined program retentive and configuration of disabled points. Memory is regularly validated by the TriBus hardware-voting circuitry.
The model 3008 Main Processors provide 16 megabytes of DRAM, which is used for the control program, sequence-of-events data, I/O data, diagnostics and communication buffers.
In the event of an external power failure, the integrity of the user-written program and the retentive variables is protected for a minimum of six months.
