Product Description:

The CML10.1-NN-210-NB-NNNN-NW is a Control Main Unit produced by Bosch Rexroth Indramat and belongs to the CML IndraControl Hardware series. As a compact programmable logic controller, it serves as the central processor in distributed machine architectures and coordinates I/O, motion, and communication tasks across automated equipment. In these systems, the main unit manages cyclic data exchange between local modules and higher-level control functions so separate machine sections can run in a synchronized sequence. Its compact format fits modular control racks used in packaging, assembly, and material-handling lines where predictable control response is required. The controller can also support coordinated task flow between field devices and machine-level functions during continuous operation.

The unit uses CPU design variant 1, which corresponds to the processor configuration used by the controller. It includes 32 MB of DRAM for user logic, diagnostics, and motion data, while 32 kB of NvRAM retains process values after power is removed. That memory arrangement supports routine control execution, status buffering, and retained machine data without requiring external battery-backed storage for basic tasks. An Inline housing profile allows DIN-rail installation beside I/O slices, and passive cooling is provided without a fan, so heat is dissipated by natural convection inside the enclosure. This arrangement helps the controller fit narrow cabinet layouts where space around neighboring modules is limited.

The controller is configured with no additional design features, which keeps the hardware arrangement straightforward for standard applications. It also has no on-chip SRAM, so temporary high-speed data storage must be handled through the available system memory or external resources when needed. This layout is suited to compact cabinets that combine logic processing, communication handling, and distributed I/O management in one central unit. It can serve as the control point for modular equipment that must coordinate sensor inputs, actuator commands, and networked machine sections within a single automation platform. The result is a controller layout focused on core processing, memory retention, and modular integration.
