Product Description:

The CML75.1-3P-905-NA-NNNN-NW is a control processor produced by Bosch Rexroth Indramat for the CML IndraControl Hardware series. It serves as the core of distributed machine architectures, executing motion logic and coordinating field devices across automated lines. By combining user application code with network communication in one modular housing, the unit can replace separate PLC and communication modules in compact cabinet designs where controller space is limited.

The controller is equipped with 4096 MB of DRAM, giving the runtime environment enough volatile memory for large application programs and buffering of process data during operation. For real-time variables that must survive power cycles, it includes 16 MB of battery-backed SRAM. The unit has no NvRAM, so long-term data retention must rely on external storage or network-based data handling. An integrated PROFIBUS interface supports cyclic communication with drives, I/O stations, and operator panels on the same fieldbus segment. The housing uses an Inline mechanical format that mounts flush with adjacent modules and shares a common backplane connection. Thermal management relies on the metal enclosure and operates without a fan, which reduces moving parts in the controller.

The CPU design is identified as variant 1, which indicates the baseline processing version in this hardware family. The numerical code 75 places the unit among the higher-capacity CML models, making it suitable for larger applications and shorter control cycles than lower-tier members of the line. As a Control Main Unit, it can act as the central processor while additional expansion slices provide the required digital or analog I/O for the machine. Attached slices can be added as application needs change, while control execution remains in the main unit.
