Product Description:
The CML65.1-3P-500-NA-NNNN-NW is a compact logic controller produced by Bosch Rexroth Indramat within the CML IndraControl Hardware series. It serves as the primary processing unit in distributed automation cells, coordinating motion axes, I/O islands, and human-machine interfaces over fieldbus networks. This arrangement lets the controller exchange commands and status data locally, which helps keep distributed equipment synchronized during fast machine cycles. By mounting the controller on the machine frame, the design shortens signal paths and reduces cabinet space while retaining deterministic cycle times for machine tool, packaging, or material-handling lines.
The unit uses an Intel Celeron M running at 1.0 GHz, giving enough processing capacity for PLC logic, interpolation routines, and diagnostic services. A base memory pool of 256 MB DRAM buffers real-time variables and recipe data during normal operation. That memory supports temporary storage for process values, status tables, and application data while the controller handles cyclic tasks. The CPU is built as variant 1 within the modular hardware family. For plant communication, the inline backplane includes a dedicated PROFIBUS interface that supports cyclic I/O exchange and acyclic parameter access at rates up to 12 Mbit/s. Neither NvRAM nor SRAM is installed, so retentive data must be stored in DRAM or transferred to a supervisory system when required.
The controller uses an inline housing, allowing adjacent modules to slide together on a DIN rail without external cabling between the CPU and expansion slices. The format keeps the control assembly compact and reduces the number of jumper connections between neighboring modules. Thermal control is passive, and the unit operates without a fan, which avoids forced airflow and helps in dusty environments. Within the IndraControl portfolio, it is identified as a Control Main Unit. Its position in the 65 series indicates compatibility with 24 V DC rail supplies and matching digital and analog I/O slices.
