Product Description:

The CML40.2-NP-220-NA-NNNN-NW is a control main unit manufactured by Bosch Rexroth Indramat for the CML IndraControl Hardware series. It serves as the central controller that executes motion sequences, program logic, and network coordination for automated production cells. By combining the real-time kernel and fieldbus master in one compact enclosure, the device removes the need for a separate industrial PC and helps keep cabinet layouts compact. This arrangement is suited to machines that need one controller to manage axis commands, logic processing, and communication at the same time in packaging, handling, and general factory automation equipment.

Processing is handled by an AMD Geode LX800 embedded CPU clocked at 500 MHz. Bosch Rexroth identifies this hardware as revision 2, indicating the second revision of the CML40 platform. System memory includes a base allocation of 64 MB of soldered DRAM plus a user-addressable pool of 32 MB for application code and data. This split keeps protected resources available for diagnostics and system buffers while leaving a separate area for the control program, motion tasks, and operating data handled by the user application.

Non-volatile resources consist of 64 kB of NvRAM, providing secure storage for recipes, parameters, and fault logs when power is removed. A built-in PROFIBUS interface links the unit to drives and remote I/O without extra communication cards, so distributed devices can be connected over the same control network. The electronics are packaged in an Inline housing that snaps directly onto a DIN rail for tight side-by-side mounting with other IndraControl modules. The controller operates without a fan, so thermal management relies on passive convection and normal enclosure airflow to remove heat from the processor and power regulators while avoiding moving cooling parts.
