For A6TBXE/A6TBY36E/A6TBX54E/A6TBY54E/A6TBX70E (common cathode; source) long 2m.Output type: transistor drain.
Output points: 16 points.
Load voltage: DC24.
Load current: 2A.
Connection mode: terminal row.
Common public end points: 8.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF A2NCPUP21-S1 Manual .
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC A2NCPUP21-S1
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control A2NCPUP21-S1 Manual .
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three. Input and output points: 2048 points.
Input / output data points: 8192 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
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 A2NCPUP21-S1 Manual .
Modular: PLC is the basic components of a separate module MITSUBISHI PLC Manual .
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 MITSUBISHI PLC Manual .
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 MITSUBISHI PLC Manual .
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 measuure of how much the user application can store the number of indicators A2NCPUP21-S1 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 A2NCPUP21-S1 Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
