MITSUBISHI A68ADC Manual A68ADC User's Manual

Input voltage: AC100-240V.
Rated output: DC5V, 3A and DC24V, 0.6A.
The power supply module is connected with the external power supply, and the DC5V is provided with the AnS programmable controller,
They are inserted in the slot of the special power supply component on the base board,
The output of the DC5V is powered by the power supply on the substrate to the component A68ADC User's Manual.
The input voltage of the component is related to the selected model A68ADC
A1S61PN/62PN has Deng generation A1S61P/A1S62P, A1S61PEU/A1S62PEU. ME-NET interface unit
Structured text language is a programming language that describes a program with a structured description of the text.
It is a programming language similar to a high level language A68ADC User's Manual. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
Mainly used for other programming languages more difficult to achieve the user program.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit.
The function module is used to represent the function of the module,
Different function modules have different functions A68ADC User's Manual.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the control scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Control system with complex scale and complex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced. NSD servo system.
A73CPU (P21/R21) -S3 dedicated.
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.
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.
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.
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 acccording to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A68ADC Manual .
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% A68ADC Manual .
The following describes the centralized control system I/O points of the estimate.
