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.

Features and Functionality

Application programming is done on the PCM112 using 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 Simulink diagrams.

The software runs on any electronic control module that supports MotoHawk.

Working directly in the Simulink environment, application developers can convert application models into files that can be programmed directly into Woodward production hardware in a single build step.

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

Once an application has been generated and loaded into the PCM112 controller via the CAN port, the

users can view variables and tune the controller using appropriate service interface tools such as Woodward’s ToolKit or MotoTune.

Connections to other devices (such as diagnostic tools) are accomplished through other CAN ports available 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 attached to an aluminum enclosure using thermally conductive adhesive and then closed and sealed with an aluminum cover.

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

The 8923-2241 includes the 1751-6685 module and mounting kit.
