Product Description:

The PPC-R02.2N-N-T2-P2-NN-FW is a modular control unit produced by Bosch Rexroth Indramat within the PPC Controllers series. It functions as a motion and I/O coordinator, supplying deterministic command processing to linked servo drives and field devices in automated assembly lines, packaging cells, and material-handling systems. By combining computational logic with network interfaces, the device manages axis positioning, sequence control, and data exchange between higher-level PLCs and subordinate drive modules. This allows one controller to synchronize drive responses with machine events such as sensor changes, interlocks, and sequence handoffs.

The unit belongs to design version 2, and its backplane pinout matches second-generation PPC racks. For network communication, it includes an Ethernet 10 Mb interface identified as ETH01, which provides TCP/IP connectivity for programming, diagnostics, and peer-to-peer data transfer. A separate Profibus DPS01 port allows it to operate as a fieldbus slave so that a master PLC can read registers and issue control words with standard Profibus telegrams. That arrangement lets the controller exchange process data with plant-level automation while keeping motion-related tasks local to the rack. The controller is built in a RECO housing, so it slides into a RECO rail and uses the rail for protective grounding and heat dissipation.

Because the internal RAM and Flash are fixed, the unit is supplied with no memory expansion, so program size and data logging must fit the factory baseline. Despite that limit, the module operates as the primary control unit inside compact cells where cycle times favor embedded logic over external PCs. This layout suits machines that rely on onboard execution instead of a separate industrial PC. Deterministic bus refresh rates are managed by the Series 2 scheduler, and watchdog functions preserve state integrity during power interruptions.
