How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc AJ71QLR21 PDF datasheet. .
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 AJ71QLR21
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 AJ71QLR21 PDF datasheet. .
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. QnA/ACPU bus connection.
1 joint.
Applicable model: A956WGOT. AnS, QnAS bus connection, the reader to write program 1 channel connection AJ71QLR21 PDF datasheet.
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.
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.
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.
This phenomenon is called the I/O delay time effect. Input type: DC input, positive common end.
Input points: 8 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA.
Output form: transistor output, leakage type.
Output points: 8 points.
OFF leakage current: 0.25mA.
Output protection function.
Rated load voltage / current: DC24V/0.5A.
External connection: /2 line 2~4 line type.
Waterproof connector type.
Strong waterproof type of IP67 protection grade.
No need to stop the system can be replaced module.
Without the use of tools can be a simple connection, save time.
Terminal resistor built-in.
Can be installed along the 6 direction.
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 thee timeliness is strong AJ71QLR21 PDF catalog.
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 AJ71QLR21 PDF catalog.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
