Overview Manuals Applications Programming Diagnostics Firmware

Features:

  • Executes one channel of the three-processor Tri-GP architecture.
  • Uses a dedicated I/O processor for the 2 Mbit/s field-data path.
  • Provides flash, DRAM, shared memory and monitored NVRAM resources.
This ordering code identifies the Tri-GP v2 main processor fitted to the 2101S2 processor baseplate.

Three processors run the project in parallel and use TriBus communication to maintain channel agreement.

Firmware, application checksum, baseplate wiring and all network settings must be controlled during replacement.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Executes process-control and safety logic in a Tri-GP v2 controller.
  • Coordinates triplicated I/O data and controller diagnostics across the three channels.
  • Restores one processor channel while the approved online-maintenance procedure is followed.
  • The control application is stored in flash and executed from local processor memory.
  • TriStation 1131 manages the controller project, downloads and online maintenance functions.
  • Project checksum and retentive-variable behavior must match the validated system baseline.
  • TriBus and diagnostic buses allow the three processors to compare channel operation.
  • Battery, power, communication and alarm states are exposed through front indicators and system diagnostics.
  • A fault in one channel is isolated so the remaining processors can continue the configured control function.
  • Processor firmware must be approved for the installed Tri-GP v2 hardware and TriStation project.
  • Firmware changes are controlled maintenance events and require a saved application and rollback plan.
  • All three processor channels should be checked for the intended revision after service.
Description
Triconex 3101S2 is one of the three main processors required by a Tri-GP v2 controller. Each channel runs independently while high-speed TriBus links let the processors compare data and maintain fault-tolerant operation. Three MPC860A processor channels use separate DRAM, flash and retentive memory while exchanging voted information across the TriBus.

A dedicated I/O processor handles the two-megabit-per-second I/O bus, leaving the program processor to execute application logic. Local flash, DRAM, shared memory and battery-monitored NVRAM support program storage, diagnostics and retained data. A dedicated I/O processor and the high-speed I/O bus keep field-data handling separate from application execution in the Tri-GP v2 controller.

Replacement planning must preserve a three-module processor set, approved firmware, project checksum and the 2101S2 baseplate arrangement. Record Ethernet, Modbus, alarm-relay and debug connections before disturbing the controller. Dual logic-power inputs, network and serial service connectors, alarm relays and the 2101S2 baseplate define the installed processor assembly.

Technical notes
3101S2 replacement requires a verified Tri-GP v2 firmware and application baseline; do not mix an unapproved processor revision into the three-channel set.
