Using a modem middle modular connector unit faces to transmit data transmission speed: 0.3-14.4kbps.
PLC is the use of " sequential scanning, and constantly circulating " way to work A1ADP-SP  PDF.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work A1ADP-SP  PDF A1ADP-SP 
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user aaccording to the control requirements of the coexistence of the user in the memory of the program,

From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work A1ADP-SP  PDF MITSUBISHI User's Manual A1ADP-SP  Manual. The main unit of the AS-i system
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 User's Manual MITSUBISHI User's Manual.
This phenomenon is ccalled the I/O delay time effect A1ADP-SP  User's 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 CCPU A1ADP-SP  Manual.
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.
