Product Description:
The CML40.2-NP-330-NA-NNNN-NW is a Control Main Unit produced by Bosch Rexroth Indramat for the CML IndraControl Hardware series. Installed in machine cabinets, it supplies deterministic application logic, synchronizing drives, I/O slices, and human-machine interfaces throughout an automated cell. By combining a low-power processor with industrial communication ports, the unit provides a compact platform for real-time control tasks such as axis interpolation, safety interlocks, and process monitoring. It is intended for OEM machine builders that need embedded control performance without using PC-class hardware.
A core clock of 500 MHz sets the execution rate for the controller’s task scheduler, giving predictable scan times for PLC and motion functions. Application code executes from a base DRAM pool of 64 MB, and this volatile memory supports user programs, operating system kernels, and communication buffers. Retentive data, such as machine counters and recipe values, is preserved in a dedicated 128 kB NVRAM, so power cycles do not erase production metrics. Thermal management is simplified because the hardware operates without a fan, allowing silent operation in sealed cabinets where airflow is restricted. Field connectivity is provided through a PROFIBUS master/slave interface, enabling deterministic exchange of I/O images with drives, sensors, and remote terminals over a single twisted-pair bus.
Processing tasks are handled by the embedded AMD Geode LX800 system-on-chip, which balances low power dissipation with the integer performance needed for motion algorithms. The controller is supplied in CPU design variant 2, which supports floating-point arithmetic for kinematic calculations. An Inline housing profile aligns the device with adjacent I/O modules on the DIN rail, reducing wiring distance and maintaining a consistent installation depth. The hardware is revision level 40, which keeps the platform aligned with current IndraControl software tools without adding extra design options to the base unit.
