MITSUBISHI A173UHCPU-S1 Manual A173UHCPU-S1 SV13/22 SFC Programming Manual

Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DC5V output 2A DC24V/.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
User program storage capacity: it is a measure of how much the user application can store the number of indicators A173UHCPU-S1 Programming Manual A173UHCPU-S1
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.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage A173UHCPU-S1 Programming Manual.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load A173UHCPU-S1 Programming Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action. 3C-2V/5C-2V coaxial cable single bus remote I/O network (remote I/O station).
Q mode.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
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.
Semiconductor circuit with memory function.
System program memory and user memory.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation A173UHCPU-S1 Manual .
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
User memory: user program storage area and work data storage area.
Composed of random access memory (RAM) A173UHCPU-S1 Manual . User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years.
