LOW LEVEL PROGRAMMING
Low-level programming languages are "machine-oriented": their purpose is to produce code that the processor can execute directly, or that can be easily translated into executable instructions. They are the foundation for talking to hardware and optimizing system-level performance.
DIALOG WITH MACHINES
Languages. Assembler & Co.
Among the available languages there are:
• Assembly Language: is, among the programming languages, the closest one to the actual machine language, although it is different
compared to the latter. Erroneously is often called "assembler", a term that instead identifies only the "assembler" program that converts
assembly language in machine language.
• C Language: is a high-level programming language that integrates low-level language features,
such as the machine language and the assembly, this is why the term "medium level".
PLC. Programming devices.
PLC is a specialized controller in process management or control.
It runs a program and processes the digital and analog signals from sensors and directed to the actuators present in a plant.
In order to fulfill his duties, it has to be programmed.
PLC programming is normally done with a PC on which a specialized software
allows you to create programs to be downloaded to the PLC CPU memory.
These programming software can read the program directly from CPU memory, and view the program on your PC.
