Product Description:

Bosch Rexroth Indramat produces the CML75.1-NP-900-NA-NNNN-NW as part of the CML IndraControl Hardware series. The module serves as the central computational element within modular PLC and motion platforms on automated production lines. By coordinating input processing, program execution, and network communication, it links field devices with higher-level supervisory systems and maintains deterministic task scheduling required for repeatable machine cycles. It fits into rack-based assemblies common in packaging, assembly, and material-handling cells, where a single controller often coordinates both logic and motion functions.

Inside the controller, a CPU design variant 1 processor governs real-time logic, and its instruction throughput is supported by 4096 MB of DRAM allocated for code, buffers, and diagnostic data. Thermal management is simplified because the electronics are supplied without a fan, so mounting positions must allow natural convection around the housing. The electronics sit in an inline housing that mates with neighboring modules through a backplane, which minimizes cable runs and keeps the assembly compact. Fieldbus traffic is handled through a PROFIBUS interface, enabling cyclic data exchange with drives, remote I/O, and HMI nodes across the plant network. No additional design features are included.

For nonvolatile resources, the hardware is configured with no NVRAM, and it also has no SRAM, so retentive data must be stored externally or rebuilt at startup after a power cycle. The platform belongs to series 75, which places it within the electrical revision used by compatible modules in the same control family. As a Control Main Unit, it manages scan time and bus arbitration for the IndraControl station while coordinating data flow between local modules and networked devices. The lack of moving parts can support stable long-term operation in cabinet-based automation systems.
