Input channel number: 4.
Output channel number: 2.
Occupy I/O points: 64.
A1S63ADA analog input / output combination components can be analog / digital / digital / analog conversion,
The input and output signals can be voltage or current,
Offset and gain can be set and stored A2ACPUP21-S1.
The length of time required to execute the instruction, the leength 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 A2ACPUP21-S1.
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 A2ACPUP21-S1 MITSUBISHI A2ACPUP21-S1.
This phenomenon is called the I/O delay time effect. Transmission line unit for MELSECNET/MINI (-S3) twisted pair data link.
Loop: twisted pair I/F.
Remote station: light I/F (plastic fiber).
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered MITSUBISHI A2ACPUP21-S1.
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system MITSUBISHI A2ACPUP21-S1.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc..
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation.
Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Optical data communication line.
Each scanning process. Focus on the input signal sampling. 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.
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.
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. 16 bit binary number is a word,<
Every 1024 words are 1K words A2ACPUP21-S1. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
