Streptococcal pharyngitis or strep throat is caused by group A beta-hemolytic streptococcus (GAS). It is the most common bacterial cause of cases of pharyngitis (15â30%). Common symptoms include fever, sore throat, and large lymph nodes. It is a contagious infection, spread by close contact with an infected individual.A definitive diagnosis is made based on the results of a throat culture.Antibiotics are useful to both prevent complications and speed recovery.ommon symptoms include fever, sore throat, and large lymph nodes.

A programmable logic controller (PLC), or programmable controller is an industrial digital computer which has been ruggedised and adapted for the control of manufacturing processes, such as assembly lines, or robotic devices, or any activity that requires high reliability control and ease of programming and process fault diagnosis.
When you upload the Structured Text PLC program to your PLC, the programming software you use will compile your program. This means that it will translate the code to a sort of machine code which can be executed by the PLC. The compiler uses the syntax of the programming language to understand your program.tructured Text is PLC programming language defined by PLCOpen in IEC 61131-3. The programming language is text-based, compared to the graphics-based ladder diagram. At first, it may seem better to use a graphical programming language for PLC programming. But in my opinion, that is only true for smaller PLC programs.
