Product Description:
The CML25.1-PN-400-NN-NNC1-NW is a control main unit produced by Bosch Rexroth Indramat within the CML IndraControl Hardware series. Deployed as the central processor in modular automation racks, it manages program execution, fieldbus communication, and deterministic task scheduling for motion or process lines. This role lets the controller coordinate logic, communication, and responses across linked machine sections from one rack-mounted control point. It can also serve as the timing reference for both discrete control and synchronized automation tasks within the same installation.
Computation is handled by a Renesas SH 7785 CPU that operates at 576 MHz, providing the cycle time required for multi-axis interpolation and fast Boolean operations. The controller is factory-equipped with 128 MB of DRAM, giving adequate runtime space for IEC 61131 task stacks, user variables, and real-time buffers. For plant-wide communication, the unit carries an integrated PROFIBUS interface, enabling deterministic exchanges with drives, valves, and distributed I/O under the DP protocol. This connection supports data exchange with distributed devices where consistent update timing is required for coordinated machine behavior. Cooling is passive, and the electronics are specified without a fan, so airflow calculations and filter maintenance are eliminated.
The mechanical layout follows an inline housing concept that mates directly to neighboring modules through bus connectors, minimizing wiring and preserving DIN-rail width. A factory-installed connector set is included, noted as with a connecting plug, allowing immediate field termination of power and network leads. The CPU design variant is 1, which standardizes boot diagnostics and memory mapping across the 25 series. The unit has no NvRAM, so recipes or trend logs must be stored on external media or transmitted to a supervisory system. External retention keeps long-term records separate from controller memory and leaves the processor focused on runtime control tasks.
