Product Description:

The CML75.1-3P-900-NA-NNNN-NW is a programmable logic controller core produced by Bosch Rexroth Indramat as part of the CML IndraControl Hardware series. Installed on a DIN rail beside decentralized I/O terminals, the module executes real-time sequencing, arithmetic, and diagnostic tasks for assembly lines, material-handling stations, and process skids. It hosts application code, manages deterministic cycle times, and exchanges operating data between field devices and higher-level control systems. This makes it well suited to machines that need centralized logic in a compact cabinet layout.

It includes 4096 MB of DRAM, which gives the controller substantial working memory for user programs, runtime data, and motion-related functions. The enclosure uses an Inline form factor, so neighboring power and bus connections align neatly with adjacent modules on the rail. Communication with remote drives and decentralized I/O takes place through a PROFIBUS interface, allowing cyclical data exchange across established industrial networks. The unit operates without a fan, so cooling remains passive and there are no forced-air paths through the housing. It is supplied as CPU design variant 1, which indicates the base processor arrangement used on this controller platform.

There is no NVRAM for battery-backed data retention, and static or additional dynamic memory is not included in the base hardware. The controller belongs to series 75, which places it within the 75-series platform used for this product line. The device functions as a Control Main Unit, so it can take the master role on the backplane while companion modules provide communication or supply functions when the application requires them. Program retention and recipe handling rely on external storage or network-based services rather than onboard nonvolatile memory.
