CPU constitution

Sequence and data, PLC is an integral unit.
In the user view, unnecessarily detailed analysis of the internal circuit of the CPU, but each part is working mechanism should be enough to understand. The controller CPU CPU work, by its reading instruction, interpretation and execution of instructions instruction. However, the pace of work is controlled by the oscillation signal. Operator for digital or logic operations, working under the command of the controller. Intermediate result registers involved in computing, and storage operations, it also means a unitary controller deer Bru ao lt;? Br> CPU speed and memory capacity are important parameters for the PLC, which determines the operating speed of the PLC, IO number and software capacity etc., thus limiting the control scale.
