Design any machine interface, generally have to consider the system response time, user assistance mechanism, error information processing and command mode four aspects A1SJPB92D  Hardware Manual A1SJPB92D  User's Manual A1SJPB92D 
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 A1SJPB92D  Hardware Manual A1SJPB92D  User's 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 A1SJPB92D  Hardware Manual A1SJPB92D  User's Manual. Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:0.2.
Internal storage RAM memory capacity: 64K
PLC in the program execution stage: according to the order of the user program order to store the order of each instruction,
After the corresponding operation and processing, the result is written to the output status register,
The coontents of the output status register are changed with the execution of the program A1SJPB92D  Hardware Manual A1SJPB92D  User's Manual.
Output refresh phase: when all instructions are executed,
The output status register is sent to the ouutput latch in the output refresh stage,
And through a certain way (relay, transistor or transistor) output, drive the corresponding output equipment A1SJPB92D  Hardware Manual A1SJPB92D  User's Manual. .
