XM2100.01-01-31-31-301-NN-113N3NN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-301-NN-113N3NN is a programmable automation controller manufactured by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. It acts as the central logic and motion unit in industrial machines, executing PLC sequences, coordinating real-time fieldbus traffic, and linking higher-level supervisory networks. By combining embedded computing resources with dedicated communication ports, the device replaces multiple stand-alone PLC, motion, and gateway modules and streamlines cabinet layouts in material handling, packaging, and machining applications. Its role is to keep control tasks, network exchange, and machine response inside one compact platform so surrounding hardware can be reduced.

The controller's processing core is an Intel Atom E620 600 MHz CPU that handles cyclic tasks, interrupts, and protocol stacks. A paired 512 MB RAM block supplies workspace for variable tables, motion data, and visualization buffers, while the operating image resides in 1 GB of onboard flash so it is retained after power isolation. A control voltage of 24 V DC lets the unit share the same supply rails used by standard sensors, relays, and other cabinet devices. The integrated 1 Gbit Ethernet port supports rapid project transfer and low-latency diagnostics, allowing direct connection to standard computers or plant networks. Local execution of logic and communication tasks helps the controller respond quickly to machine events without depending on a separate industrial PC.

On the field side, the Sercos interface can operate with cycle times down to 250 µs, giving axis drives tightly synchronized position updates during coordinated motion. User data that must survive an emergency stop is stored in 128 kB of retentive memory, and removable archiving is available through the SD card slot and two USB interfaces. The device meets Protection Class III, enabling operation on separated extra-low-voltage circuits, and it continues to function at elevations up to 4700 m without additional cooling. Mechanical loading on DIN rails remains low because the housing weighs only 0.7 kg, which helps when several control components must be installed close together in a compact cabinet.
