Product Description:

The CML65.1-3P-504-NA-NNNN-NW is produced by Bosch Rexroth Indramat for the CML IndraControl Hardware series. Classified as a control main unit, it integrates the application processor, fieldbus interface, and memory resources required to coordinate distributed I/O and motion modules on an automation line. In a machine cabinet, the unit acts as the central PLC and HMI host, handling deterministic task scheduling and supervisory communication to higher-level plant networks. This arrangement allows one controller to manage machine logic, operator interaction, and communication with surrounding modules from a single location.

The unit uses an Intel Celeron M processor running at 1.0 GHz, so sequential logic and numeric routines are executed on an x86 platform used in industrial control systems. Base DRAM is provisioned at 256 MB, while volatile scratchpad functions rely on 8 MB of battery-independent SRAM. These memory resources support real-time buffering of recipes, counters, and diagnostic logs during operation. The module communicates with decentralized drives and I/O over a single-channel PROFIBUS master interface that supports legacy fieldbus integration. Thermal management is passive because the electronics are supplied without a fan, and the CPU uses design variant 1 as the standard performance grade for the 65 hardware family.

The enclosure follows an Inline profile, so power, fieldbus, and service connectors line up with adjacent modules and help reduce wiring depth inside the cabinet. There is no onboard nonvolatile user storage, so long-term data retention must be handled by external flash cards or network servers. This separates retained application data from the controller hardware when recipes or archives are maintained elsewhere on the network. Mechanical code 65 keeps the footprint consistent across the IndraControl range.
