Learn about how cpu execute a program in the siemens plc, it reads the inputs from the input module then values are saved to pii (process image. The monitoring of plant status and control of its actuator elements is done by devices connected to the controller's hardware Siemens plcs dominate industrial automation worldwide, powering everything from simple machine control to complex process automation systems.
SIOS
Run, stop, and program a plc can be placed in run or stop, or occasionally program mode, usually through physical or virtual methods
But what do these modes.
In this article, we will learn about the execution of the program in the plc Many people want to learn plc programming directly without knowing what happens around it. A valid program must exist in the cpu before it can enter run mode In this article, i am going online with the cpu, changing the mode to “run” and exploring the status information and general properties of the cpu
