Memory card interface (AD59-MEF), parallel interface.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust.
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on step by step A6DIN2C A6DIN2C
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be. Program 2 channel connection, AnCPU/QnACPU use.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add A6DIN2C.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations. Input voltage range: DC24V.
Output voltage: DC5V.
Output current: 8A.
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 A6DIN2C.
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 control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Optical data communication line function (GI cable).
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 A6DIN2C.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words A6DIN2C. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
