Product Description:

The PPC-R22.1N-T-Q2-P1-NN-FW is a programmable control unit produced by Bosch Rexroth Indramat within the PPC Controllers series. It occupies a compact RECO housing and has IP20 protection, so it is intended for installation inside a protected cabinet. In an automation cell, the unit coordinates motion or process sequences by exchanging data with drives and higher-level PLCs, thereby acting as the central processor for axis and machine control tasks. Its cabinet-mounted format suits machine sections where the control platform must remain protected from direct contact and airborne debris.

Electrical consumption is limited to 24 VDC at a maximum draw of 1.2 A, yielding a total power demand of 52 W. A PowerPC 266 MHz processor runs the operating software and user application, while 32 MB of SDRAM stores dynamic data used during control operation. The controller supports fieldbus timing through a Sercos interface that reaches 16 MBaud. Three digital inputs and two digital outputs permit direct connection of sensors or relays for local interlocking. Additional panel information is provided by a 4-digit alphanumeric status display, and two serial ports allow connection of service interfaces or local communication devices. Version 1 keeps the standard RECO form factor so the unit can be mounted alongside other automation modules without special adapters.

For networked installations, the device offers 2 × ARCNET channels for deterministic cross communication, a Profibus-DP master interface for distributed I/O, and an Ethernet port rated at 10/100BaseT (RJ45) for cell-level data exchange. Application code and the operating system are stored on a 32 MB CompactFlash module, while nonvolatile variables reside in 128 KB NVRAM. This separation allows stored software and retained machine data to be handled independently during normal operation. No additional memory expansion slots are present, which keeps the hardware layout fixed and easy to follow in controlled machine designs. The combination of onboard networking, local I/O, and solid-state storage supports compact control architectures without requiring external cooling devices.
