Product Description:
The MDCP41-01 central processing unit is produced by B & R Automation and belongs to the MDP CPU Controllers series. It is intended to host the user program, manage local memory resources, and coordinate digital and analog signals between machine sensors, actuators, and higher-level networks. By integrating processing, nonvolatile storage, and a serial maintenance port in one compact assembly, the module serves as the control core of smaller stand-alone machines or distributed cells that require deterministic logic execution. This layout keeps essential control functions in a single unit and supports straightforward integration into compact automation systems.
Its computing core uses a Motorola 6303 microcontroller, and each thousand instructions in the program requires about 4 ms/K Instructions of execution time, allowing predictable cycle calculations. Application code can reach 4.7 K Instructions, and dynamic variables reside in 16 KByte SRAM, which is retained only while power is present. For recipe data or calibration constants, a block of 16 KByte EEPROM provides nonvolatile storage without external cartridges. The processor can address 7168 8-bit registers for arithmetic, bit manipulation, and buffer handling. One online port is included with a TTY electrical layer and supports a single concurrent online session for program download or status monitoring.
The controller offers 800 one-bit flag addresses for internal coils and status markers. Field expansion allows up to 264 discrete points and 80 analog channels through modular backplane adapters, while four peripheral processors can offload tasks such as axis control. The TTY maintenance connection is electrically isolated to protect both the host PC and the PLC electronics. A software clock provides time stamping for sequence timing or shift reports without a hardware real-time clock. These functions support applications that need orderly I/O handling, stored operating values, and stable control behavior during routine machine operation.
