This time, we conducted in-depth discussions with Siemens on multiple key topics at our Fuqing factory. As a Siemens service provider, our company provides products and technical support in multiple product areas, including FA (factory automation), PA (process automation), GMC (general motion control), MTS (small and medium-sized drive systems), CRANE (crane control systems), MI (drive motors), etc. Whether it's fault repair, spare parts supply, or system upgrade and optimization, we have the ability to provide customers with efficient and accurate services. To ensure the efficiency and consistency of our services, we will optimize our service process strategies, improve service quality, and diversify our product and service needs, starting from the key concerns of our customers. As a company deeply rooted in the field of industrial control for many years, we are...
In PLC applications, it is not recommended to directly connect the alarm to the output terminal, especially in safety alarm and emergency handling situations. PLC output modules are divided into relay output type and transistor output type. The former is suitable for driving high-power loads, while the latter is not suitable. The working current and voltage of the alarm are relatively high, and direct connection may damage the PLC or cause safety issues. When using a relay output PLC, the alarm can be connected to the output terminal, but attention should be paid to independent power supply, reasonable control signal, reliable reset operation, and alarm safety performance. When designing an alarm system, appropriate solutions should be selected based on the PLC output type and load characteristics to ensure system reliability. In the app...
What are PLC and RTU? What is the difference between the two? I believe many people are at a stage where they roughly know what it is, but cannot accurately say it. This article will tell you in detail! What is PLC PLC (Programmable Logic Controller) can be used as a programmable controller, and its most basic and widespread application field is to replace traditional relay circuits and achieve logic control and sequence control. PLC consists of CPU and input/output modules. It has multiple control functions, data acquisition, storage and processing functions, mathematical operation functions, and input/output interface conditioning functions. In addition, there are communication networking functions, human-machine interface functions, and editing and debugging functions. Mainly applied in traditional industrial control f...
Several methods of program protection for S7-1500 The program protection methods for S7-1500 and S7-300/400 are not exactly the same 1. Read protection In the hardware configuration, open PLC Properties - Protection to set access permissions as needed. When selecting three protection levels other than "full access permission (no protection)", an access password needs to be set. Protection level: No protection, write protection, read-write protection, fully protected (password required for upper computer communication) 2. Protection of proprietary technology for program blocks The 1500CPU program blocks, including OB, FC, and FB, all support encryption functionality. DB also supports encryption function. After encryption, the attribute is read-only, and variables can be seen, but they cannot be added or deleted. Right c...
According to the national statutory holiday schedule, our company's specific holiday arrangements are as follows: Holiday period: January 1, 2025 (Wednesday), with one day off. Normal work will resume on January 2.
It is important to determine the reference potential point Regarding the issue of not being able to read the value, if there is always no change in 32767, the value already exists, it is just an overrange. If the value is 0, then attention should be paid to whether there is a problem with the analog quantity. Using a multimeter to measure the on-site signal does not exceed the limit. Why do these two phenomena occur? This is because the selected reference potential is different. For example, if the signal coming from the site is 5V, the first thing to ask is what voltage is the reference point? 10-15 is 5V, and -10~-5 is also 5V. If the reference point of the measuring end is 0V, there will be a problem with the measurement, so it is necessary to ensure that both ends are equipotential. The reference potential point of the analog module is MA...
Flexible robots and rigid robots are both types of industrial robots, and the main difference between them lies in their structure and usage: Structure: Flexible robots typically have more flexible body cavities and/or joint structures, allowing for more complex form transformations, while rigid robots are composed of rigid rods and their joint connections, with relatively fewer degrees of freedom in motion. Control method: Flexible robots usually use force and visual perception based control systems, while rigid robots mainly use programming control. Application areas: Flexible robots are mainly used in healthcare and service robots, such as surgical robots, rescue robots, grass cutting robots, etc; Rigid robots are mainly used in automated production equipment such as assembly, spot welding, painting, cutting, etc. on industrial production lines...
