1, the fault phenomenon is: "Module I is not online." 2, the cause of the malfunction: The machine control system has multiple function modules, the system itself has a strong self-diagnostic function. Maintenance staff had swapped the same module position, still reported that "Module I is not online." Because there is no information, maintenance is more difficult. The professional maintenance personnel inspection, the internal modules are all an independent veneer extension, controlled by a SCM, a microcontroller and the host computer online, according to module features and processing technology analysis, the control mode of each module is different, although some modules The same internal hardware, but the control program is different, so the modules are not interchangeable. Power check, the control system self-diagnostic function is operating normally, and the alarm is "module I is not online," so I check the module. Module I was visually no abnormalities, power checks CPU operation should be normal, the status of the integrated circuits are also normal. Check the memory is EEPROM, which is characterized by the ability to rewrite at any time, in the specific operation of EPROM to be flexible and convenient, but as its reliability is not as high as the EPROM, due to some interference, may be mistakenly rewritten, so suspect memory failure. 3, Troubleshooting: Read the contents of the memory, found several data is questionable, to be disassembled to be analyzed, the program self-test after boot, such as pass, by the host computer alarm. Look at the back of the control program, and some do not like the formal program is not like the data. According to the control program pattern analysis, some control programs have been rewritten, and therefore can not pass the self-test. According to the processing technology to write control procedures, and verified on the PC, self-test can be passed. Because in the actual operation does not require data to be written, so rewrite the program with EPROM curing. On the machine power check, the module I no longer alarm, the whole machine can be normal operation. Through this example, maintenance personnel should be able to determine the hardware fault, but also have some knowledge of control software, and be able to operate the use of computers.
Self Drilling Screw
Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
So what is the use of drilling screws?
1 stainless steel plate, metal plate, galvanized steel plate, engineering installation.
2 metal curtain wall metal light compartment and other indoor and outdoor installation.
General Angle steel, channel steel, iron plate and other metal materials combined installation.
4, automobile, container, shipbuilding, refrigeration equipment and other assembly projects.
