Product Description:

The PPC-P11.1N-N-Q1-NN-NN-FW control unit is manufactured by Bosch Rexroth Indramat as part of the PPC Controllers series. It is supplied as a PCI short card that plugs into an industrial PC backplane and executes motion, logic, and diagnostic tasks for distributed automation cells. Acting as the primary coordinator on a fiber-optic Sercos network, the module exchanges real-time data with servo drives, I/O stations, and higher-level PCs, enabling synchronized positioning and process control in packaging, converting, and material-handling equipment.

Physical dimensions are 107 mm in height and 175 mm in length, so the card fits standard 3U slots without obstructing adjacent devices. The board connects to the host through a 32-bit PCI bus at 33 MHz, and this interface supplies power while transferring data between the CPU and field connections. The DAQ03 link ring card handles cross communication and supports fiber-optic traffic to remote nodes. Program storage is provided by 16 MB of CompactFlash memory, and this version does not include additional memory expansion. Front-panel status is shown on a 1-digit 7-segment display that presents initialization codes and runtime errors.

The controller supports up to 40 Drives on a Sercos network, allowing multi-axis machines to be supervised from a single slot controller. A female 15-pin D-Sub connector is provided as the programming port for connection to a laptop or service HMI. The watchdog safety relay can switch external circuits at 24 V and carry up to 150 mA, so critical actuators can be de-energized automatically if processor activity stops. Communication between link ring segments is routed over fiber-optic cable to reduce electromagnetic interference, and the industrial PC housing helps shield the electronics from airborne contaminants during continuous plant operation.
