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 FR-A820-01540-2-60
This phenomenon is called the I/O delay time effect.
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 MITSUBISHI .
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. Input type: DC input, positive common end.

Simple wiring through quick connector.
Can be installed along the 6 direction.
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. A1SG60 is an empty cover that is used to plug in the unused I/O slot on the main board or on the extended board.
A1SG60 is a reserved dummy module I/O point to PLC extended I/O system.
With the switch on the module can be set to retain the I/O point,
Can set 16 points, 32 points, 48 points and 64 points. Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.Series Name: A953GOT.

Design any machine interface, generally have to consider the system response time, user assistance mechanism, error information processing and command mode four aspects.
System response time is too long to be the most users in the interactive system,
In addition to the absolute length of the response time, the user is also very concerned about the difference in response to different commands in response time,
If too wide users will be difficult to accept; user assistance mechanism should be integrated,
Avoid overlay systems that cause users to turn to a guide and have to browse a large number of irrelevant information;
Error and warning informaation must be selected in terms off user''s clarity and meaning,
At the same time, it should be as far as possible to provide some suggestions on the recovery of errors MITSUBISHI FR-A820-01540-2-60.
In addition, when the error message is displayed, the effect is better if it iss ssupplemented by the auditory (Bell) and visual (special color) stimulus;
Command mode is the best menu and keyboard commands, for the user to choose MITSUBISHI FR-A820-01540-2-60.
