Product Description:

The PPC-R22.1N-T-Q1-P2-N1-FW belongs to the PPC Controllers series produced by Bosch Rexroth Indramat. It is a modular control unit that occupies one slot in a RECO backplane and coordinates drive-based tasks such as axis interpolation, process sequencing, and data exchange for higher-level PLCs. Its role in industrial automation is to execute motion logic locally so the main controller can offload deterministic, time-critical functions. Because control calculations are handled near the drive hardware, response timing remains more consistent during coordinated motion and sequence changes.

The card communicates with neighboring PPC modules through Cross Communication DAQ03, a backplane channel that transfers position words and status bits in real time. A DPS01 Profibus interface lets the controller appear as a fieldbus slave, giving external PLCs deterministic access to parameters and diagnostic data. The controller uses Design Version 1, which matches the hardware layout and buffer arrangement used by this revision. This keeps addressing and internal data handling aligned with the installed hardware. The unit is supplied without memory expansion, so the available onboard RAM and flash set the application size. Its RECO housing guides cooling air across the PCB and uses keyed connectors that reduce the chance of incorrect insertion.

An optional NSW01 PLS module can be docked on the front panel. It adds position-latch capability for registration or print-mark triggers without increasing the Profibus scan load. The added input is useful when fast sensor events must be captured at the axis level instead of waiting for the higher-level fieldbus cycle. Classified as a Control Unit, the board works with compatible drive and axis modules in the same platform. Its deterministic cross-module timing allows synchronous motion groups to share encoder data and stop conditions even when multiple network segments are present.
