Data communication line module (optical cable) Master / local station for A3VTS multiplex system
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
MITSUBISHI PLC protection and chain procedures AJ65SBTB2N-8S PDF.
Protection and chain is an indispensable part of the program, must be carefully considered AJ65SBTB2N-8S
It can avoid the control logic confusion caused by illegal operations. Series Name: A953GOT.
Size: 6 inches.
Resolution: 320 * 240.
Display device: STN monochrome display.
Display color: monochrome (white and black).
Power supply: DC24V.
The built-in RS-232 communication interface AJ65SBTB2N-8S PDF.
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 AJ65SBTB2N-8S PDF.
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. A1SD51S is an intelligent communication module used in ANS series,
Can use the AD51H-BASIC language to make online or offline programming on the universal terminal or computer,
Multitasking can also be performed with up to two programs at high speed.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work.
