I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
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.
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.
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.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command): with 1 s coaxial data communication line function.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process MITSUBISHI A38HBEU. 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
A38HBEU
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 MITSUBISHI A38HBEU.
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 MITSUBISHI A38HBEU.
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 A38HBEU MITSUBISHI. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. ROM capacity: 16K bytes (max 7K step).
A2A, A2A-S1, A3A, A2N, A2N-S1, A3N storage box A38HBEU MITSUBISHI. Cable for extended use in multiplexing unit.Input and output points: 256 points.
Input / output data points: 256 points.
Program capacity: 6k.
Basic command processing speed (LD command) s:1.0.
Internal storage RAM memory capacity: 16k.
Optical data communication line function with power supply A38HBEU MITSUBISHI.
Input / output data control mode conversion.
It is possible to enter the control of the output data as the following 3.
(1) input: direct mode, output: direct mode.
(2) input: I/O impression update mode, output: direct mode.
(3) input: I/O impression update mode, output: I/O impression update mode.
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 22~4 A38HBEU.
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 MITSUBISHI A38HBEU.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
