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.
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 A171SCPU-S3 Dedicated Instructions Manual A171SCPU-S3 Programming Manual A171SCPU-S3
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 A171SCPU-S3 Dedicated Instructions Manual A171SCPU-S3 Programming Manual.
This phenomenon is called the I/O delay time effect. Cable length: 0.7 meters
Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable A171SCPU-S3 Dedicated Instructions Manual A171SCPU-S3 Programming Manual. 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 initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc.. "Interface: RS232C.
Transmission distance: 15 meters.
A1SJ71UC24-R2/R4/PR computer communication components can be relieed on external intelligent devices such as computers and PLC for communication, the components are as follows:
Full / half duplex transmission,
4 special communication protocools,
No protocol and bidirectional mode,
Protocol selection switch function,
The optional baud rate, the highest 19 A171SCPU-S3 Dedicated Instructions Manual A171SCPU-S3 Programming Manual A171SCPU-S3 Dedicated Instructions Manual A171SCPU-S3 Programming Manual. 2K,
Since the echo diagnostic test.
