The built-in RS-232 communication interface.
Memory card: 3M.
Design any machine interface, generally have to consider the system response time, user assistance mechanism, error information processing and command mode four aspects A2ASCPU-S60 Manual .
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 selected 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 A2ASCPU-S60 Manual MITSUBISHI PLC Manual MITSUBISHI PLC Manual .
In addition, when the error message is displayed, the effect is better if it is supplemented by the auditory (Bell) and visual (special color) stimulus;
Command mode is the best menu and keyboard commands, for the user to choose. SI/QSI/H-PCF/ wide H-PCF optical cable double loop PC (control station / common station) / remote I/O network (remote master station) MITSUBISHI PLC Manual . With external power supply function.
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.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC andd 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 A2ASCPU-S60 Manual A2ASCPU-S60 Programming Manual.
This phenomenon is called the I/O delay time effect.
