Product Description:

The CML40.1-SP-220-NA-NNNN-NW is a Control Main Unit produced by Bosch Rexroth Indramat for the CML IndraControl Hardware series. As a standalone CPU module, it provides deterministic logic and communication functions to coordinate axis drives, I/O, and HMI stations inside distributed factory cells. The unit is installed on a DIN rail within a control cabinet and acts as the primary decision layer for motion sequences, safety interlocks, and process supervision across an automation network. Its hardware resources and fieldbus support allow tight cycle times when integrating multiple servo drives or valve terminals.

At the heart of the controller is a National Geode SC1200 processor that operates at a core speed of 266 MHz. This embedded x86 CPU handles IEC 61131 tasks and user programs within a real-time operating system. Base memory is fixed at 32 MB of DRAM, giving enough space for sizable PLC projects and temporary variables during runtime. No onboard SRAM is configured, so temporary registers reside entirely in DRAM. For retentive data, the board carries 64 kB of nonvolatile RAM, allowing the application to store machine counters or calibration offsets across power cycles without external media. The controller uses CPU design variant 1 for standard IndraControl compatibility.

The mechanical layout follows an Inline housing concept, so the module clips directly beside matching power supplies and I/O slices without an additional backplane. The hardware has no additional design features. Heat is removed passively, and the model is specified without a fan, which supports use in dusty environments and sealed cabinets. Network traffic is exchanged through a built-in PROFIBUS interface, allowing cyclic data exchange with drives or remote I/O at configurable baud rates. Function blocks can reference libraries classified under Series 40, which identifies the product generation and diagnostic structure for this hardware family.
