Introduction
The Power PMAC UMAC ARM CPU board (part number 604112-10x) provides a powerful
computing engine for UMAC (Universal Motion and Automation Controller) rack-mounted
systems. This 3U-format Eurocard (100 mm x 160 mm) can communicate with multiple
accessory boards over the UBUS backplane. These accessory boards provide interfaces to the
various machine elements for both motion and non-motion I/O, digital and analog.
The Power PMAC UMAC ARM CPU board can communicate with all accessory boards that the
older Turbo PMAC2 UMAC CPU board (603766-10x) could use. In addition, it can
communicate with a new generation of “PMAC3” UMAC accessory boards for motion, MACRO
ring, and I/O that employ a new generation ASIC and a 32-bit data bus on the backplane.
The Power PMAC UMAC ARM CPU board acts as both a dedicated controller and a general-
purpose embedded computer. It uses the Linux operating system with a hard-real-time kernel that
guarantees determinacy of tasks such as servo loop closure.
