A1SJ71UC24-R2/R4/PR computer communication components can be relied on external intelligent devices such as computers and PLC for communication, the components are as follows:
Full / half duplex transmission,
4 special communication protocols,
No protocol and bidirectional mode,
Protocol selection switch function,
The optional baud rate, the highest 19 AY42-S4 Manual AY42-S4 User's Manual AY42-S4 2K,
Since the echo diagnostic test. Series Name: A950GOT.

Some mechanical industries, such as machine tools, textile machinery, electronic equipment and other industries,
In the country has been developed for decades of history, relatively speaking, is relatively mature industry, in the long run,
These industries also exist the needs of equipment upgrades AY42-S4 Manual AY42-S4 User's Manual.
In this upgrading process, there will be some small, has been using relatively low-end products manufacturers are eliminated,
But there are also a lot of enterprises in the process of equipment renewal,
Re positioning the needs to find those that can meet their development plans,
Equipment suppliers to help them improve their productivity AY42-S4 Manual AY42-S4 User's Manual. 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 function (GI cable).
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.
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.
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 thhe user application can store the number of indicators AY42-S4 Manual AY42-S4 User's 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 llogical operation instructions each account for 1 words AY42-S4 Manual AY42-S4 User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
