A6TEL MITSUBISHI parts A6TEL

Multiple CPU units for A3VTS multiplex system.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units MITSUBISHI A6TEL. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words A6TEL
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage MITSUBISHI A6TEL.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action MITSUBISHI A6TEL. Output points: 32 points.
Voltage: DC12/24V.
OFF leakage current: 0.1mA.
Output type: bidirectional thyristor output (type sink) MITSUBISHI parts.
Response time: 2ms.
32 points / a common end.
50 point terminal station.
With the surge absorber.
Each scanning process. Focus on the input signal sampling MITSUBISHI parts. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh MITSUBISHI parts.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the controll requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A6TEL.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation MITSUBISHI A6TEL.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
