Product Description:
The CML45.1-3-500-NA-NNNN-NW is a control main unit manufactured by Bosch Rexroth Indramat for the CML IndraControl Hardware series. As the central processor in a modular controller stack, it handles motion coordination, logic execution, and network communication for dispersed drives and I/O stations in automated machinery. The controller is assembled in an Inline housing so that it can clip directly onto a DIN rail alongside power supplies and expansion modules, keeping cabinet depth uniform.
An embedded AMD LX800 processor supplies the computing core, and its clock rate of 500 MHz allows deterministic program cycles for mid-range machine tasks. The board is fitted with 256 MB of DRAM, giving the PLC sufficient volatile memory for user programs, firmware, and motion tables while still leaving headroom for diagnostic buffers. Real-time fieldbus exchange is implemented through a single SERCOS III interface; this Ethernet-based protocol carries synchronized drive commands and status data without the need for separate communication cards. Hardware option code 1 denotes the CPU design variant, identifying the heat-sink profile and component population that match the 45-series backplane and its thermal envelope.
The unit is categorized as a Control Main Unit, positioning it as the master device for the application layer while subordinate modules handle field wiring. Within the CML family, it belongs to series 45, which standardizes connectors, firmware tools, and mechanical dimensions across the product range. Both the digital I/O configuration and the onboard NvRAM are listed as none, so deterministic tasks that demand retain-memory or local signal terminals must be implemented through add-on modules connected to the SERCOS III network or the side-mount bus, keeping the base CPU focused solely on cycle execution and real-time communication.
