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 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.

At the heart of the PCM112 controller is a powerful 32-bit Freescale MPC5644A microprocessor

and an auxiliary 16-bit Freescale MC9S12G microcontroller, both running Woodward’s ControlCore operating system.

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.The MicroNet TMR®’s “2-out-of-3” voting structure ensures that problems are responded to correctly and that prime movers continue to operate safely with or without any single point of failure.

The controller’s robustness, fault tolerance, accuracy and availability make it the first choice for turbine and compressor OEMs and operators worldwide.

The superior architecture and diagnostic coverage of the MicroNet TMR® results in 99.999% system availability and reliability.The MicroNet TMR® can be

MicroNet TMR® can be used as a component of a protection and safety system, making the entire system compliant with IEC61508 SIL-3. IEC61508 calculation and application assistance.

 Typical MicroNet TMR® application experience and use:

 Refrigeration compressors (ethylene, propylene)

 Methane and Syngas Compressors

 Gas Cracking Compressors

 Gas charging compressors

 Hydrogen Recovery Compressors

 Critical turbine generator sets

 Turbine Safety Systems

For IEC61508 SIL-3 based applications, MicroNet systems require a MicroNet Safety Module (MSM).

The MSM serves as the system’s SIL-3 logic solver, and its fast (12 ms) response time and integrated overspeed and acceleration detection/protection make it ideal for critical high-speed rotating motor, compressor, turbine or engine applications.
