Description
NI PXIE-8861 Bus Interface Module
PXIE-8861 consists of operators, controllers, registers and data, control and status buses to realize the link between them, the CPU unit also includes peripheral chips, bus interfaces and related circuits. Memory is mainly used to store programs and data, is an indispensable component of the PLC unit.
PXIE-8861 should still have enough understanding of the working mechanism of each part. the controller of the CPU controls the work of the CPU, which reads instructions, interprets instructions and executes instructions. However, the working rhythm is controlled by oscillating signals. Operators are used to perform digital or logical operations and work under the command of the controller. Registers are involved in the operations and store the intermediate results of the operations, which also work under the command of the controller.
