Tricon 3008 Main Processor | Model 3008 for v9.6 Systems

Description

Meet the Model 3008 – Tricon Main Processor

• Model 3008 Main Processors work with Tricon v9.6 and later systems.
• Every Tricon main chassis needs three MPs installed.
• Each MP talks to its I/O subsystem and runs your control program.
• They work together using triple-modular redundancy (TMR) for safety.

Technical Specifications (Tree View)

• ▹ Model: 3008 Main Processor
• ▹ System compatibility: Tricon v9.6 and newer
• ▹ Microprocessor: Motorola MPC860, 32-bit, 50 MHz
• ▹ Memory:
  • 16 MB DRAM (non-battery backed)
  • 32 KB SRAM (battery backed)
  • 6 MB Flash PROM
• ▹ Tribus communication rate: 25 Mbit/s with 32-bit CRC protection
• ▹ Tribus isolation: 32-bit DMA, fully isolated
• ▹ I/O Bus & Comm Bus processors: Motorola MPC860, 32-bit, 50 MHz

LED Status Indicators

• PASS – Module passed self-diagnostics
• FAULT – Module has a fault. Replace it.
• ACTIVE – Module is running user control program
• MAINT1 / MAINT2 – Maintenance indicators
• COM TX / COM RX – Transmitting/receiving on COMM bus
• I/O TX / I/O RX – Transmitting/receiving on I/O bus

Sequence of Events (SOE) & Time Sync

• MPs check discrete variables for state changes (events) each scan.
• When an event occurs, MPs save the variable state and time stamp in SOE buffer.
• Connect multiple Tricon systems via NCMs for consistent time base.
• This ensures accurate SOE time-stamping across large plants.

Built-in Diagnostics

• Extensive checks validate MP, I/O module, and communication channel health.
• Transient faults – recorded and masked by hardware voting circuit.
• Persistent faults – diagnosed. Replace the faulty module while system runs (hot-swap).
• MP diagnostics verify:
  • Fixed-program memory
  • Static RAM

Installation Guide

• Install three Model 3008 MPs in the main Tricon chassis.
• Push each module firmly into its slot until locked.
• Check PASS LED after power-up. Green means OK.
• For Tricon v9.6 or later only. Older firmware not compatible.
• Refer to the Planning and Installation Guide for Tricon Systems for full details.

Easy Debug & Maintenance

• LEDs give instant status. No software needed for basic checks.
• Hot replacement – replace a faulty MP without shutting down the system.
• Transient fault log helps find intermittent issues.
• Use Tricon engineering software to read diagnostic records.

Compatibility

• Works only with Tricon v9.6 or newer systems.
• Compatible with all Tricon I/O modules (analog, digital, etc.).
• For integration with other PLCs, use NCM communication modules.
• Can connect to Modicon Quantum via Modbus or gateway.

Certifications & Safety

• Tricon systems are TÜV certified for safety-critical applications.
• Meets IEC 61508 SIL 3 requirements.
• Triple-modular redundancy (TMR) architecture for high availability.
• Designed for use in emergency shutdown and fire/gas systems.

Frequently Asked Questions (FAQ)

• Question: Why do I need three Model 3008 MPs?

  Answer: Tricon uses TMR. Three MPs vote on outputs. One can fail without stopping the system.

• Question: Can I use Model 3008 with older Tricon v8 or v7?

  Answer: No. Model 3008 requires Tricon v9.6 or later. Older versions are not compatible.

• Question: What happens if one MP shows FAULT LED?

  Answer: Replace it while the system runs. The other two MPs keep control.

• Question: Is the 32 KB SRAM battery replaceable?

  Answer: Yes. The battery backs up SRAM. Change it during scheduled maintenance.

• Question: Does this module support hot-swap?

  Answer: Yes. Tricon supports hot replacement. No need to power down.

Experience-based Q&A (Field Notes)

• Question: My system shows PASS on all MPs but one I/O module is dead.

  Answer: Check the I/O bus connections. Replace the I/O module first. MPs are likely fine.

• Question: The ACTIVE LED blinks slowly. Is that normal?

  Answer: Yes. Blinking means the MP is running the control program. Steady on/off indicates a problem.

• Question: We see transient faults recorded weekly. Should we replace the MP?

  Answer: Not yet. Transient faults are normal in noisy environments. Monitor persistent faults instead.

Buying Guide – Select the Right Main Processor

• Choose Model 3008 if your Tricon system runs v9.6 or newer firmware.
• For older Tricon systems (v7 or v8), look for older MP models (e.g., 3007).
• Always buy three units per chassis – one spare recommended for critical sites.
• Check your memory needs: 16 MB DRAM is enough for most safety programs.
• Need SOE time-stamping across multiple Tricon racks? Order NCM modules separately.
• Contact us for bulk discounts or trade-in options for older processors.
