XM2100.01-01-31-31-301-NN-102NNNN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-301-NN-102NNNN is an embedded control unit manufactured by Bosch Rexroth Indramat for the XM21 IndraControl Systems series. It functions as a central logic platform that executes motion sequences and coordinates fieldbus traffic. It also hosts application software for automated machinery and production lines. This arrangement allows one compact controller to manage machine logic, network communication, and process timing from a single platform.

An onboard Intel Atom E620 600 MHz processor runs the real-time operating system, while 512 MB of RAM buffers variables and diagnostics during execution. Program code resides in 1 GB of read-only memory, which preserves stored data through power cycles. Control voltage is supplied at 24 V DC, so the unit connects directly to standard cabinet power rails. One engineering Ethernet port rated at 1 (1 Gbit) supports high-speed network access and remote service. Two RJ45 connectors operate as Sercos master ports, EtherCAT I/O master capability supports distributed modules on the same scan, and three extension module slots accept add-on cards for additional interfaces. A single USB device port enables configuration from a PC, and one USB host port connects removable media for log extraction or license keys.

The housing carries an IP20 protection rating and belongs to protection class III, so it relies on an extra-low-voltage supply for safety isolation. Operation is permitted up to a maximum altitude of 4700 m without derating, which covers most terrestrial installations. Physical dimensions of 100×126.3×74.1 mm allow dense mounting on DIN rails inside control enclosures, and the overall mass of 0.63 kg keeps the load on panel hardware low. Cooling is provided by convection through side vents. The platform also provides deterministic sampling rates when the embedded real-time kernel is synchronized over the Sercos network bus.
