Product Description:

The CML45.1-NP-500-NA-NNNN-NW Control Main Unit is produced by Bosch Rexroth Indramat for the CML IndraControl Hardware series. Installed as the central controller in a machine cabinet, it executes user logic, manages deterministic task scheduling, and supervises communication with distributed drives, sensors, and machine-level peripherals across the control network. By hosting the runtime software for Series 45 hardware, the unit serves as the processing core of mid-range automation lines that require coordinated motion, safety interlocks, and reliable data exchange with supervisory systems during continuous operation.

The computational platform uses an AMD LX800 embedded processor running at 500 MHz, providing the processing speed needed for real-time control tasks and communication handling. A base memory of 256 MB DRAM is soldered to the board, supplying space for application code, process variables, and visualization data. The CPU is identified as variant 1. For plant networking, an integrated PROFIBUS master/slave port supports 12 Mbit communication with drives, remote I/O, and HMI panels without requiring a separate interface module. This arrangement allows the controller to handle machine logic and bus communication within one compact platform.

The electronics are built into an inline housing that mates directly with neighboring I/O slices, so power and bus connections can pass through the assembly without additional cabling. This format also helps the controller fit compact cabinet layouts where modular I/O is mounted beside the CPU. Thermal dissipation relies on convection because the product is supplied without a fan, which helps reduce maintenance in dusty environments. Persistent storage for recipe or diagnostic data is external because the controller has no NVRAM and no SRAM. This arrangement is suitable for applications where retentive data is stored on flash media or on a network server.
