Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DAC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Optical data communication line.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way A2CCPUP21 datasheet. Easy maintenance.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage
A2CCPUP21
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load A2CCPUP21 datasheet.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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 A2CCPUP21 datasheet. 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 iin 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 A2CCPUP21 PDF datasheet.
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 A2CCPUP21 PDF datasheet.
