RS-232:1, RS-422/485:1.
Transmission speed: 0.3 ~ 19.2kpbs.
Computer connection function.

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 A273UHCPU
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 A273UHCPU 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 A273UHCPU PDF. Input type: DC input, positive common end.
Input points: 8 points.
Enter the response time: 0.2ms below, below 1.5ms, 5ms below, 10ms the following.
Rated input voltage / current: DC24V/7mA.
Output form: transistor output, leakage type.
Output points: 8 points.
OFF leakage current: 0 MITSUBISHI Programming Manual. 1mA.
Output protection function: No.
Rated load voltage / current: DC24V/0.5A.
Externnal connection: 3 line /2 line type A273UHCPU Manual .
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool MITSUBISHI Programming Manual. 26 point with the connection transformation adapter 16 type 1 point input CC-Link unit to install the special connection transformation adapterAnS, QnAS bus connection, the reader to write program 1 channel connection MITSUBISHI Programming Manual.
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 aand 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 usse of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A273UHCPU Manual A273UHCPU Programming Manual.
This phenomenon is called the I/O delay time effect.
