NUCLEAR 1E MAIN PROCESSOR VARIANT
Triconex 3008N Enhanced Main Processor III, 16 MB
Certified 3008N variant mapped to the standard 3008 architecture
SECTION 01
Product Description
The Triconex 3008N is the nuclear-qualified Enhanced Main Processor III, 16 MB variant for Tricon v10.x systems. Its certified-equipment mapping points to the standard 3008 hardware description, where three processor modules execute and compare controller work through the triplicated TriBus architecture.
Inside the 3008N, a 50 MHz Motorola MPC860 performs main processing while a second MPC860 handles communication activity. The 16 MB DRAM supports active application and I/O data, 32 KB of battery-backed SRAM preserves retained information, and 6 MB Flash provides nonvolatile storage.
The 3008N moves processor comparison data over a 25 Mbps, CRC-protected TriBus and exchanges I/O over a 375 Kbaud RS-485 interface. A separate optically isolated RS-232 diagnostic port provides the service path, keeping diagnostic access apart from controller I/O traffic.

SECTION 03
Main Processor III Data Handling
The 3008N uses the standard 3008 processor and memory architecture under its nuclear-qualified model designation.
Communication processor
A separate 50 MHz MPC860 handles the communication interface rather than combining both roles on one execution path.
Retained and stored data
Battery-backed SRAM preserves retentives, while Flash provides nonvolatile storage independently of working DRAM.
SECTION 04
TriBus and Communication Bus Operation
The 3008N separates interprocessor voting, I/O transfer and communication-module traffic across dedicated buses.
Processor comparison
The 25 Mbps TriBus uses CRC protection and isolated DMA to synchronize and compare the three processor channels.
I/O bus path
The RS-485 I/O interface moves module data at 375 Kbaud between the processor bank and installed I/O modules.
Communication path
A separate RS-485 communication interface runs at 2 Mbps for data exchanged with communication modules.
SECTION 05
Common Questions
What does the N mean in Triconex 3008N?
The 3008N is the nuclear-qualified equipment variant. Its official mapping directs hardware specifications and architecture to standard model 3008. The N suffix should remain in the requested model even when standard-model technical data is consulted.
Can Triconex 3008N specifications be read from model 3008?
Yes, because the certified-equipment table explicitly maps 3008N to 3008. This mapping supports the architecture and specification values used for the certified variant. No other 3008-family suffix should be substituted solely because it shares the underlying processor architecture.
How many processor modules are used with Triconex 3008N?
A Tricon controller uses three Main Processors. Their data is synchronized and compared through TriBus. The three modules still operate as separate processor channels rather than one processor with three logical tasks.
Which memory in Triconex 3008N is battery backed?
The 32 KB SRAM is battery backed for retained information. The 16 MB DRAM serves active working data and is a separate memory resource. Flash memory separately stores nonvolatile content and should not be confused with either SRAM or DRAM.
What speed does the Triconex 3008N TriBus use?
The standard 3008 architecture used by 3008N operates TriBus at 25 Mbps. The path includes 32-bit CRC protection and isolated DMA. I/O traffic and communication-module traffic use their own RS-485 interfaces in addition to TriBus.
Is Triconex 3008N the same model as 3009?
No. The 3008N maps to 3008 and uses the 3008 processor architecture; 3009 has a different processor, memory capacity and chassis-dependent TriBus rate. Processor type, memory capacities and diagnostic connector should all be checked before treating two MP models as equivalent.
