The Schneider 140CPU11302 is a CPU module used in the Modicon Quantum Automation System. It is a programmable controller with built-in memory and communication ports.
140CPU11302 The Central Processing Unit (CPU) is a super-sized integrated circuit that is the core of a computer's computing and control unit. Its function is mainly to interpret computer instructions and to process data in the computer software.
The CPU consists mainly of an operator (Arithmetic Logic Unit, ALU) and a cache (Cache) and a bus (Bus) for data, control and status between them. Together with internal memory and input/output (I/O) devices, these are the three core components of an electronic computer.
The CPU can be logically divided into three modules, the control unit, the computing unit and the storage unit, which are connected by the internal CPU bus.
The 140CPU11302 is a single-slot programmable controller with built-in executive memory, application memory, and communication ports. It uses flash memory technology for the CPU's executive memory and instruction set. The application program is stored in battery-backed RAM, and the battery can be serviced while the CPU is running.
The 140CPU11302 is part of the Modicon Quantum range by Schneider Electric. The CPU module is designed for material handling, packaging, and textile machines usage.
The CPU module is for use on the Quantum local I/O backplane and must be plugged into the backplane. It supports 3 distributed and 2 remote networks. It has 1 Modbus Plus port and 1 Modbus RS232 port. The bus current requirement for the CPU module is 780 mA, and it requires a lithium battery with a capacity of 1.2 AH and a battery life of 10 years.
The CPU module is programmed using the ProWorx 32 software. It has 256 K RAM and 8 K User Logic. The digital and analog outputs of the CPU module can be used to control processes and machines based on programmed instructions. The CPU module can be used for logic, process sequencing, timing, coupling, and arithmetic functions.
The CPU module is part of the Quantum system, which includes Quantum Interface modules and Quantum I/O modules. Different system configurations require different power supply modes, such as Standalone mode, Standalone Summable mode, and Redundant mode. The clock frequency of the module is 20 MHz.
