Product Description:

The PPC-R22.1N-N-N1-N2-P2-FW is a programmable control unit produced by Bosch Rexroth Indramat within the PPC Controllers series. It is installed as a RECO-format rack module and coordinates motion sequences, data processing, and fieldbus communication for connected drive axes in industrial automation cells. By interpreting program logic and passing setpoints, the unit frees the machine PLC from high-speed interpolation tasks and concentrates axis control in a dedicated platform.

This controller operates from a nominal bus of 24 VDC and draws up to 1.2 A through the backplane, so cabinet power supplies must deliver that steady low-voltage rail. A Profibus fieldbus slave interface designated Profibus DPS01 is fitted, allowing deterministic exchange of I/O words with the cell PLC. Internally, program images are stored in a soldered flash device rated at 32 MB, and there is no plug-in memory expansion. Two RS232/RS485 channels provide 2 serial ports for a local HMI or service connection. The housing follows the RECO mechanical standard, uses R22.1 hardware with design version 1, and comes with three slot positions populated as NSW01, NSW01, and DPS01.

The module carries 32 PLS outputs that switch deterministic events such as glue guns or cutter drives. Each line can source up to 250 mA at 24 VDC and is refreshed every 250 µs update cycle for tight synchronization with axis positions. Signals are distributed across two plug-in cards, giving 16 outputs per card and leaving the third bay free for an Option Card PLS module if higher channel density is required. Installation flexibility is enhanced by 3 expansion slots that accept additional NSW logic or communication boards. Because memory expansion is not equipped and Ethernet is absent, the controller relies on its existing flash capacity and fieldbus channel for program loading and network communication.
