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 AJ71UC24 PDF AJ71UC24
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 AJ71UC24 PDF. .
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. Type of input: DC leakage.
Input points: 32 points.
Input voltage: DC24.
Input current: 7mA.
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 AJ71UC24 PDF.
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 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. Cable length: 25 meters.
For QCPU and GOT (need A9GT-QCNB) connection.
For the connection between GOT and GOT. Analog channel: 4 channels.
Input / output (resolution): 0 ~ 4000.
Conversion speed: 100ms/4 channel.
Analog module installation.
Power supply: DC24V.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong AJ71UC24 datasheet.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy too guarantee the timeliness AJ71UC24 datasheet.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
