Product Description:

The CML20.1-NP-120-NA-NNNN-NW is an IndraControl central logic module built by Bosch Rexroth Indramat and placed within the CML IndraControl Hardware series. As a dedicated controller, it coordinates machine sequences, manages distributed inputs and outputs, and links motion drives to supervisory systems in industrial automation environments. This unit runs the control software that handles deterministic task scheduling and fieldbus communication for assembly cells, packaging lines, and material-handling stations. Its central role allows connected modules to exchange commands, status signals, and process data through one logic platform.

Processing performance is supplied by a STMicroelectronics ST40 CPU clocked at 192 MHz, giving adequate cycle time for interpolation, logical branching, and diagnostic routines. Both the base and configured DRAM capacity are 16 MB, providing volatile workspace for the real-time operating system during active control tasks. Non-volatile program retention is handled by 64 kB of NvRAM, so power-off parameters and machine counters persist without external batteries. The board integrates a PROFIBUS interface, enabling deterministic communication with remote I/O and drive amplifiers over the common serial fieldbus. This communication path supports consistent data exchange between the controller and connected automation devices.

Hardware layout follows an Inline housing format that allows the unit to snap directly onto adjacent modules without extra wiring depth. Thermal management relies on convection because the unit is supplied without a fan, so cabinet airflow must accommodate the heat produced by the controller. The device uses CPU design variant 1, which matches the installed peripheral set for this module. Classified as a Control Main Unit, it occupies the head position in the rack and forwards power and data to extension cards. This arrangement supports orderly expansion when additional fieldbus or I/O modules are added beside the controller.
