Product Description:

The CML40.2-SP-330-NA-NNNN-NW belongs to the CML IndraControl Hardware series manufactured by Bosch Rexroth Indramat. Classified as a control main unit, it executes user programs, handles fieldbus exchanges, and supervises motion groups in industrial automation systems. Installed inside an IndraControl cabinet, it provides deterministic scan cycles so packaging lines, material-handling cells, and processing machinery can coordinate drives and distributed I/O without external PCs. Because it is a main control unit rather than an auxiliary interface module, it serves as the central processing point for coordinated machine functions and scheduled data exchange across the automation network.

Processing duties are carried out by an AMD Geode LX800 processor clocked at 500 MHz, which supports real-time PLC logic and embedded visualization. Runtime data reside in 64 MB of soldered DRAM, giving the controller space for application code, communication buffers, and operating data. A built-in PROFIBUS port exchanges cyclic and acyclic data with drives, valves, and remote sensors, eliminating the need for add-on bus cards. Cooling relies on passive convection, and the unit is supplied without a fan, which helps reduce noise and avoids filter maintenance in sealed control panels. No discrete SRAM is fitted, so the hardware layout remains straightforward.

Retentive items such as recipes and machine counters are stored in 128 kB of NvRAM, preserving data through power interruptions without batteries. The electronics sit in an inline housing, allowing dense side-by-side mounting while keeping terminals accessible from the front. Front-accessible terminals help keep wiring organized when modules are packed closely on a rail or mounting plate. The controller uses CPU design variant 2, indicating the second board revision of the Geode platform. Internally, it follows series code 40.
