Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:1.0.
Optical data communication line function (GI cable).
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read QD81MEM-2GBC
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. Series Name: A953GOT.
Size: 6 inches.
Resolution: 320 * 240.
Display device: STN color display.
Display color: 8 color.
Power supply: DC24V.
The built-in RS-232 communication interface.
Memory card: 1M.
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 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.
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.
