Capable of continuous thermocouple or platinum temperature measurement.
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 A1SJ71LP21GE Manual A1SJ71LP21GE Reference Manual A1SJ71LP21GE
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 the 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 use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A1SJ71LP21GE Manual A1SJ71LP21GE Reference Manual .
This phenomenon is called the I/O delay time effect. AnS, QnAS bus connection, the reader to write program 1 channel connection.A set of 5 (LOGO removable, man-machine interface provides one) A1SJ71LP21GE Manual A1SJ71LP21GE Reference Manual .

With the rapid development of microprocessor, computer and digital communication technology,
Computer control has been extended to almost all industrial fields.
Modern society requires manufacturing to respond quickly to market demand,
Production of small quantities, multi varieties, multi specifications, low cost and high quality products,
In order to meet this requirement,
Production equipment and automatic production line control system must have high reliability and flexibility,
PLC programming is to comply with the requirements of the emergence of it is based on a microprocessor based general industrial control device.
PLC programming is a digital computing operation of the electronic system,
Designed for applications in industrial environments.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timiing, counting and arithmetic operations in its internal storage,
And through the digital, analog input and output, control of various types of machinery or production process A1SJ71LP21GE Manual A1SJ71LP21GE Reference Manual .
Programmable controlller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions A1SJ71LP21GE Manual A1SJ71LP21GE Reference Manual .
