Printing and packaging equipment of PLC Systems Troubleshooting
Rely on battery power to keep the program exists. Example 5: two domestic purchases of foreign companies to spend tens of millions of used printing equipment, acceptance in foreign countries, the device using the normal, post after removal, re-installed, a device heating is not normal, one can not start. After examination, the first because of loss of control of the heating PID parameters, the second device, there is no direct procedure. Parameter is missing can we find, enter the estimated parameters, and slowly debugging significant. Process equipment was lost in trouble, because it is used, the initial commissioning engineers not found, even if found, are often out of the maintenance costs are astronomical. Then no way can only find from the domestic industry manufacturing the equipment control system transformation. These are a great loss caused by a small battery. PLC is not with the early memory card, the program exists in memory directly, while the PLC batteries are lithium batteries, with self-charging function, since the use of a long time, battery power is not very adequate. Equipment in foreign countries, we often start, battery can be charged to meet the work requirements,[link widoczny dla zalogowanych], and later in the relocation and installation process, no one noticed the battery issue, PLC for a long time in the off state, the battery power runs out, cause the program to be lost. Thus reminded of domestic enterprises in the procurement of foreign equipment selection, be sure to pay attention to the battery problems PLC. Relocation, installation, replace the battery in advance, or remove the PLC system, a separate power supply frequently to ensure equipment safety procedures. PLC digital input and output on the analog input module and output module is the implementation of PLC action components, the general problem, you can through the exchange of the same model to determine the same specifications and troubleshooting. I am here to talk about the major impact on the system module. Example 6: a user equipment, PLC Fault (error) indicator lights, the user thought it was a program failure, CPU module is sent back to re-filling process, check the original program, and there are no errors,[link widoczny dla zalogowanych], so that CPU module will test the alarm,[link widoczny dla zalogowanych], because Test platform module for this system is not very comprehensive, suspected to be the number of modules on the floor due to incorrect specifications, relative to the Department, the possible failure is the module is bad. Inform the user of the phone system module will re-PLC removed to install a solid, boot back to normal. Each PLC system is established,[link widoczny dla zalogowanych], the address of the input and output modules have made a strict definition, and even the type of module, specifications are strictly defined. The system is running, CPU module will address the various testing,[link widoczny dla zalogowanych], if privately swap and replacement of modules, or other causes of loose modules for bad, will cause the CPU module is not detected, resulting in failure. Example 6, because the module is bad, resulting in the current address of the CPU module is not detected, resulting in a fault alarm. I on the next page 65) clear case price in the market overwhelmingly dominated. Fifth, service strategy: improving services to the North were die-cutting machine integrity embodied in the service users, the domestic manufacturers there is a big advantage, both to be ordered by the transport of equipment to the equipment less the middle link, the user can go directly to manufacturers to buy, On the other hand user feedback at any time, the company can always send someone to repair. North people die-cutting machine has a very good after-sales service: to provide users with pre-sales technical support, acting as a guide to help users select the appropriate type of enterprise applications; the sale of enthusiasm for the user installation and use of equipment for those users who do not know provide training; sale to provide users with the machine maintenance services, if necessary, can also provide re-training. Northern people to the user as the first, also opened a nationwide hotline counseling, a 24-hour service commitment to the scene. Sixth, the development strategy: innovation is the eternal vitality of the North who die-cutting machine with the printing market, the only way to diversity, individuality, the development of on-demand printing, advanced finishing technology has penetrated into the field. Domestic cutting confidential catch up the advanced world level there is a long way to go, the face of digitization, automation, stability requirements, the North cutting machine set off a wave of reform and innovation. Although the North who have been die-cutting machine in quality to compete with foreign manufacturers, but with the economic development, improve the technological level, but also need to constantly improve, make up the shortfall. Getting better digital printing, die cutting are also entering the digital realm, in order to meet market demand, the North of digital die-cutting machine continuously improve the level of automation and stable performance, in order to lay a good foundation for future development. Cutting competition in the market is a protracted war, to stand out it must withstand the test of the market. North people look to the future die-cutting machine has been up the courage to make the
