MITSUBISHI A1SJHCPU-S8 Programming Manual PLC Fundamentals Manual

MELSECNET/10, MELSECNET/H coaxial, input voltage: AC100-240V.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 A1SJHCPU-S8 Manual . 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 A1SJHCPU-S8
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 A1SJHCPU-S8 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 A1SJHCPU-S8 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 MITSUBISHI PLC Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Storage capacity: 64MB MITSUBISHI PLC Manual .
Applicable models: A985 (-V) /A975/A970/A960GOT (-B). A set of 5 (LOGO removable, man-machine interface provides one).
Applicable model: A95_GOT (-M3). BASIC program running.
RS-232 2 channel, RS-422 1 channel.
Serial interface, memory card interface.
How to determine the input / output device of MITSUBISHI plc MITSUBISHI PLC Manual .
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points A1SJHCPU-S8 Programming Manual.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book A1SJHCPU-S8 Manual .
