Product Description:
The CML20.1-1NP-120-NA-NNNN-NW Control Main Unit is manufactured by Bosch Rexroth Indramat as part of the CML IndraControl Hardware series. Positioned at the core of a machine controller rack, this hardware executes application code, manages deterministic communication with drives, and handles standard PLC tasks required in packaging, material-handling, and assembly systems. Its design links higher-level supervisory software with real-time field signals so that coordinated motion sequences and safety interlocks can be executed predictably.
At the heart of the controller is a STMicroelectronics ST40 processor running at 192 MHz, supplying the instruction throughput necessary for axis-synchronous logic and high-speed I/O scanning. Program and variable storage is supported by 16 MB of DRAM, which hosts the operating system, user project, and communication stacks. For data that must survive brief power drops, the unit provides 2 MB of battery-backed SRAM, while configuration keys and production counters are stored in 32 kB of NvRAM. These memory blocks affect how many motion profiles, recipes, and diagnostic records can be retained locally, and they also influence startup time and watchdog response latency.
Signal exchange with field devices is handled through a front panel with 8 inputs / 8 outputs, allowing direct wiring of limit switches, start buttons, and status lamps without an external slice. The electronics are built into an Inline housing, so the module plugs directly onto adjacent bus couplers, minimizing cabinet depth and easing DIN-rail mounting. The unit is supplied in design variant 1, signifying the standard feature set for the CML platform, and it is classified within series 20. This arrangement supports compact cabinet integration and consistent use with related control hardware.
