Using A1SJ71LP21 and A1SJ71BR11MELSECNET/10 modules,
Can be any ANSCPU module to the network system.
Two options can be provided; the optical cable token ring network and the coaxial cable token bus network.
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 A9GT-QBUS2S User's Manual A9GT-QBUS2S
This phenomenon is called the I/O delay time effect A9GT-QBUS2S User's Manual.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three A9GT-QBUS2S User's Manual. Optional features of memory card (A/FX compatible).

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 information must be seleccted in terms of 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 A9GT-QBUS2S Manual.
In addition, when the error message is displayed, the effect is better if it iss supplemented by the auditory (Bell) and visual (special color) stimulus;
Command mode is the best menu and keyboard commands, for the user to choose A9GT-QBUS2S Manual.
