PCM112-14

ECM-5644A-112-064-1400 DEV

At the heart of the PCM112 control is a powerful 32-bit Freescale MPC5644A microprocessor and an auxiliary 16-bit Freescale MC9S12G microcontroller that both run Woodward’s ControlCore operating system.

FEATURES & FUNCTIONALITY

Application programming is accomplished on the PCM112 via Woodward’s MotoHawk application software tool. MotoHawk is a rapid controls system development tool that allows controls engineers to quickly create controls software directly within Simulink diagrams, which run on any MotoHawk-enabled electronic control modules. Application developers work directly in the Simulink environment and with a one-step build are able to go from an application model to a file that can be programmed directly into Woodward production hardware.

MotoHawk provides a high-level programming environment for users who have control systems expertise but don’t necessarily have specific embedded programming skills. Once the application program has been generated and loaded into the PCM112 control via the CAN port, the user can view variables and tune the control using an appropriate service interface tool such as Woodward’s ToolKit or MotoTune. Connection to other devices, such as a diagnostic tool, is accomplished by means of other CAN ports available on the control. The desired information flow is programmed into the control via MotoTune or ToolKit.

The PCM112 control consists of a single rigid printed circuit board attached to an aluminum housing using thermal adhesive, which is then closed and sealed with an aluminum cover. Connections to the control are made via three automotive style  sealed connectors. The control can be mounted directly to the engine or frame using vibration isolators.

8923-2241 includes the 1751-6685 module plus mounting kit.
