XM2100.01-01-31-31-301-NN-101N3NN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-301-NN-101N3NN is a compact controller from Bosch Rexroth Indramat in the XM21 IndraControl Systems series. Designed for decentralized automation, the module combines motion logic and fieldbus routing in a single DIN-rail unit. It coordinates servo drives, I/O stations, and visualization clients by running IndraWorks software on an embedded platform. In production cells, packaging machines, and material-handling lines, the device executes deterministic control tasks and exchanges real-time data with higher-level PLCs and SCADA systems.

The controller uses an Intel Atom E620 processor with a clock speed of 600 MHz, which supports multi-protocol communication without a separate PC. It includes 512 MB of DDR2 RAM for user programs, data storage, and buffer operations, while a remanent memory area keeps critical variables available after power-down. Electrical integration is straightforward because the logic electronics use a single 24 VDC supply through spring terminals. The housing has an IP20 rating, so it provides touch-safe openings but requires installation inside an enclosure. Motion synchronization over Sercos is handled every 250 µs, allowing tight position loops for multi-axis assemblies with minimal jitter during trajectory execution.

The hardware supports installation sites up to 4700 m above sea level, allowing use in high-elevation plants without affecting CPU operation or communication timing. Persistent data such as machine counters or recipe identifiers are stored in a dedicated 128 kB sector that is protected from cyclic wear, which helps preserve retained information during unexpected shutdowns. The unit has a mass of 0.62 kg, so it adds little load to lightweight control cabinets. A single USB host port is available for keyboards, data transfer, or WLAN adapters when needed.
