MITSUBISHI A1SY81EP datasheet PDF

Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.20.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure A1SY81EP PDF A1SY81EP
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
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 A1SY81EP PDF.
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 A1SY81EP PDF.
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. 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. Cable 3M ffor the expansion of the floor, the expansion of a floor for every 1 units A1SY81EP datasheet. A1SG60 is an empty cover that is used to plug in the unused I/O slot on the main board or on the extended board.
A1SG60 is a reserved dummy module I/O poinnt to PLC extended I/O system A1SY81EP datasheet.
With the switch on the module can be set to retain the I/O point,
Can set 16 points, 32 points, 48 points and 64 points.
