Inter-PC fiber loop. Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line function (GI cable).
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh A0J2HCPU-DC24 Fundamentals Manual A0J2HCPU-DC24 Programming Manual A0J2HCPU-DC24
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 A0J2HCPU-DC24 Fundamentals Manual A0J2HCPU-DC24 Programming Manual.
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 A0J2HCPU-DC24 Fundamentals Manual A0J2HCPU-DC24 Programming Manual.
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 logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. AnS, QnAS bus connection, the reader to write program 1 channel connection.2 axes.
2 axis linear interpolation.
Control unit: pulse, mm, inch, degree.
Determine the location of the number of data: 400/1 axis.
40 pin connector.
Control mode: position automatic acceleration and deceleration time: 64-4999ms pulse train output DC servo MELDAS-S1 with work output.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
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 control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
MITSUBISHI PLC is the main product in the producction of MITSUBISHI motor in Dalian A0J2HCPU-DC24 Fundamentals Manual A0J2HCPU-DC24 Programming Manual.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithhmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process A0J2HCPU-DC24 Fundamentals Manual A0J2HCPU-DC24 Programming Manual.
