How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps A2USCPU-S1 Manual A2USCPU-S1
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc A2USCPU-S1 Manual . .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. AnS, QnAS bus connection, the reader to write program 1 channel connection.
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 A2USCPU-S1 Manual .
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 MITSUBISHI PLC Manual .
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on MITSUBISHI PLC Manual MITSUBISHI PLC Manual .
This phenomenon is called the I/O delay time effect. Type of input: DC leakage.
Input points: 64 points.
Input voltage: 12/DC24.
Input current: 2/5mA.
Connection mode: terminal row.
Common common point: 32.
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.
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 schemee 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 coomplex control logic,
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced A2USCPU-S1 Manual A2USCPU-S1 Programming Manual.
