Product Description:
The CML45.1-2P-500-NA-NNNN-NW is a Bosch Rexroth Indramat control main unit in the CML IndraControl Hardware series. Installed at the center of a machine controller, it executes user PLC code, manages motion profiles, and supervises diagnostic messaging for coordinated automation tasks. By combining deterministic cycle timing with integrated fieldbus access, the unit serves as the processing hub between operator interfaces, servo drives, and distributed sensors. This role allows one controller to coordinate logic execution and data exchange without requiring a separate computing platform for routine machine control.
The core processor is an AMD LX800 running at 500 MHz, providing predictable response while staying within the thermal limits of a control cabinet. The module includes 256 MB of DRAM, which provides space for IEC-61131 task pools, recipe data, and temporary trend buffers during operation. Communication with distributed stations is handled through a PROFIBUS interface that supports cyclic control traffic as well as acyclic parameter access. The electronics are contained in an inline housing, allowing direct side-by-side installation with compatible IndraControl I/O slices and helping reduce wiring distance inside the cabinet. Cooling is passive because the unit is supplied without a fan, which avoids forced airflow through the controller and supports quieter cabinet operation.
The board uses design variant 1, and it does not include NvRAM or SRAM, so retentive data is handled through flash-based resources. The unit is part of series 45, which keeps its boot and diagnostics environment consistent with related controller sizes in the same platform. It has no additional design features, so the configuration stays focused on PLC processing, fieldbus communication, and stable cabinet integration. This layout keeps the hardware centered on core control functions rather than optional multimedia or auxiliary interfaces.
