Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language MITSUBISHI PLC Programming Manual. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system A3NCPUR21
Mainly used for other programming languages more difficult to achieve the user program.
The structured text programming language uses the computer description method to describe the various kinds of relations between the various variables in the system,
Complete the required function or operation MITSUBISHI PLC Programming Manual.
Most PLC manufacturers use structured text programming language similar to BASIC language, PASCAL language or C language and other advanced languages,
But in order to be convenient, the expression methods of the statement and the types of statements are simplified.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Need to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers MITSUBISHI PLC Programming Manual A3NCPUR21 Programming Manual. Poor visibility and operability. Adapter for mounting rails. Unit connection CPU unit.Capable of continuous thermocouple or platinum temperature measurement A3NCPUR21 Programming Manual.
In addition, the temperature measurement range can be set with the use of the temperature.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of A3NCPUR21 Programming Manual.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of tthe change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the usse of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on MITSUBISHI PLC Programming Manual A3NCPUR21 Manual .
This phenomenon is called the I/O delay time effect.
