Product Description:
The CML40.2 is manufactured by Bosch Rexroth Indramat and belongs to the CML IndraControl Hardware series. Classified as a control main unit, it serves as the central processing element in modular automation racks. By coordinating motion axes, fieldbus interfaces, and local I/O, the unit executes deterministic logic for assembly lines, packaging machines, and other automated equipment. Its hardware architecture combines computation, memory, and communication in a compact form that integrates directly with IndraControl peripheral modules. This setup allows the controller to manage machine sequences and communication tasks from one housing.
At the core of the controller is an AMD Geode LX800 processor clocked at 500 MHz, supplying the throughput required for deterministic PLC cycle times below ten milliseconds. The board carries 64 MB of DRAM, which stores the real-time operating system, user application code, and data buffers without relying on external memory cards. Keeping these resources on the main board reduces dependence on add-on storage for basic operation. Hardware layout follows CPU design variant 2, where the LX800 is paired with the CS5536 companion chipset for integrated graphics and bus arbitration. An Inline housing type permits direct stacking on DIN rail signal modules, eliminating ribbon cables and shortening connections between the control unit and adjacent I/O. Direct stacking also helps keep cabinet wiring short and orderly.
Within the IndraControl product hierarchy, the controller belongs to performance class 40, placing it above entry-level logic units and below high-end motion platforms. Its designation as a Control Main Unit means no onboard I/O channels are present, so the CPU works with distributed terminals through SERCOS and PROFIBUS masters. Because the CPU depends on external terminals rather than fixed onboard channels, the control station can be adapted to different machine layouts with matching interface modules. This arrangement keeps the processing section separate from field-level hardware and supports modular rack expansion without changing the base controller.
