Product Description:

The PPC-P01.1A-N-A3-NN-NN-FW EP is a control unit manufactured by Bosch Rexroth Indramat and placed within the PPC Controllers series. As a stand-alone industrial PC, it serves as the central automation node for motion sequences coordinated over Sercos networks and other fieldbus layers, providing deterministic command execution for drives and I/O. The housing design matches standard control-cabinet layouts so the module can be seated beside power supplies and interface cards with minimal additional wiring.

This unit employs 4 MB SDRAM as its data buffer, while a separate block of 8 MB SDRAM acts as the main operating memory for the real-time kernel and application tasks. Non-volatile program storage is supplied by 4 MB of on-board flash, eliminating the need for rotating media in vibration-prone installations. Maximum load on the back-plane is limited to 1.5 A, and the board draws that current from a regulated logic rail rated at 5 VDC. A keyed connector accepts an additional 4 MB plug-in module so the controller can host larger part programs, PLC symbol tables, or diagnostic snapshots without modifying the base board.

Long-term data retention is handled by 64 KB of NVRAM, and cyclic parameters are safeguarded by an EEPROM segment sized at 256 Byte; both areas survive power loss without a battery. Processing bandwidth is delivered by a Power PC microprocessor that integrates an arithmetic unit tuned for control loops. For fiber-optic motion buses the board includes a dedicated SERCON 816 Sercos controller, enabling isochronous axis updates while freeing the CPU for interpolation and diagnostics. Together with the memory expansion socket, these embedded resources allow firmware upgrades and feature additions to be deployed without replacing hardware modules.
