Applications

The PCM112 control platform is suitable for a variety of applications, including powertrain control and electric vehicle monitoring applications.

At the heart of the PCM112 control is a powerful 32-bit Freescale MPC5644A microprocessor and an auxiliary 16-bit Freescale MC9S12G microcontroller.

Both run Woodward’s ControlCore operating system. Application programming is done through Woodward’s MotoHawk application software tool.

MotoHawk is a rapid control system dcs-sis.com development tool that allows control engineers to quickly create control software directly in a Simulink diagram that runs on any MotoHawk-enabled control system.

MotoHawk runs on the MotoHawk electronics control module. Application developers working directly in the Simulink environment.

One-step builds transform application models into files that can be programmed directly into DeWalt production hardware.

MotoHawk provides an advanced programming environment for users with control system expertise but not necessarily specific embedded programming skills.

Once the application is generated and loaded into the PCM112 controller via the CAN port.

users can view variables and adjust controls using appropriate service interface tools such as Woodward’s ToolKit or MotoTune.

Connections to other devices, such as diagnostic tools, are available through other CAN ports on the controller. The required information flow is programmed into the controller via MotoTune or ToolKit.

The PCM112 controller consists of a rigid printed circuit board that is adhered to an aluminum housing using thermal adhesive, then closed and sealed with an aluminum cover.

Connection to the controller is made via three automotive style sealed connectors. The controller can be mounted directly to the engine or frame using vibration isolators.

Description

The MicroNet TMR® control platform features a ruggedized rackmount chassis with in-line replaceable I/O modules and triple modular architecture for 99.999% availability.

This triple modular redundancy-based system consists of three independent cores (A, B, and C) housed in the platform’s compact chassis.

Each core section includes its own CPU, CPU power supply, and up to four I/O modules, which can be used for simplex I/O, redundant I/O, triple redundant I/O, or any combination of redundancy.

I/O can be expanded via a system expansion chassis or the ruggedized LinkNet HT Distributed I/O.

The platform’s high-density modules and integrated application software reduce troubleshooting time by providing first-out indication of monitored system events.

These specialized modules can time stamp discrete events in 1 millisecond and analog events in 5 milliseconds.

The MicroNet TMR® utilizes two power supplies, each supplying power to the controller from a separate power source. Within each power supply are three independent power converters, one each for the CPU and I/O sections.

This triple power supply structure provides maximum protection against single or multiple points of hardware failure.

The controller’s dedicated TMR® Discrete I/O Module is designed for critical discrete circuits.

The module accepts discrete inputs and distributes them to each individual core section, as well as outputs relay contacts to drive discrete application logic.

The module’s special TMR® outputs utilize dcs-sis.com a six-relay configuration and integrated potential fault detection logic that allows any one or two relays to fail without affecting the integrity of the output contacts.

This configuration allows routine relay testing and in-circuit repair without compromising output or system integrity.

Designed from the ground up as a turbine control system, the MicroNet TMR® controller’s actuator drive module is available with the use of single or dual redundant coils,

Proportional or integral turbine valve servos with AC or DC feedback position sensors using single or dual redundant coils.

The MicroNet TMR® controller can accommodate any combination of Woodward MicroNet I/O modules and LinkNet HT distributed I/O to provide maximum application flexibility.

Available inputs and outputs include

 Magnetic pickups (MPUs) and proximity probes

 Discrete I/O

 Analog inputs/outputs

 Thermocouple inputs

 Resistance Temperature Devices (RTD)

 Proportional and integrated actuator drives (integrated AC and DC position inputs)

 Ethernet and serial communications

 Distributed analog, discrete, thermocouple and RTD I/O available with LinkNet HT

Woodward’s MicroNet TMR (Triple Modular Redundancy) controller is a customizable digital control platform that reliably controls and protects steam, gas turbine and compressor trains.

These are system-critical applications where safety issues can arise or cause significant economic loss.
