企业如何能够实现在推动创新发展的同时，积极应对挑战，牢牢抓住发展机遇？作为数字化转型的实践者和赋能者，ABB凭借丰富的运动控制产品与数字化解决方案及服务相对接，致力于帮助中国制造企业应对数字化转型与碳排放挑战2021年的ABB中国运动控制事业部的业务总体继续保持增长趋势，业务发展的重点具体可以总结为几个关键词：低碳、数字化。我们的多个战略性项目也都有了非常好的进展。

 which will better meet China's rapidly growing market demand. "Talents are the key to innovation. ABB cooperates with more than 100 universities worldwide. In China, it has a long tradition to support education." Kang Liang said, "We cooperated with dozens of domestic universities and vocational colleges to build joint laboratories, hold technical seminars, and provide training resources. For example, we supported the growth and development of innovative talents and entrepreneurial teams through ABB Cup Smart Technology Innovation Competition and ABB Electric Innovation Challenge." In the face of the growing impact of climate issues, sustainable development is more urgent than ever. As the second largest economy in the world, China plays a vital role and has proposed a grand dual carbon target. We believe that scientific and technological innovation is the key to achieving sustainable development in the future. ABB will continue to expand its technological boundaries, promote continuous innovation, support China's green transformation and create a sustainable future. " The Global CEO Committee launched the "Empowering the Future" project, which aims to pool resources, increase talents and set up a stage for outstanding Chinese and foreign youth, and help consolidate the future foundation of world peace, prosperity and common development. ABB and other enterprises are the leading companies of the project. Last September, under the framework of "empowering the future", the "Global CEO Committee" and Beijing officially launched the "Global Young Entrepreneurs Empowerment Plan" at the 2021 Global Entrepreneurs Summit. The plan aims to serve the construction of Beijing International Science and Technology Innovation Center, build an innovation and entrepreneurship exchange platform, attract global high-end resources, and cultivate and gather outstanding young talents at home and abroad. LXN1604-6 3BHL000986P7000 Mailbox VMEbus interface provides four 32-bit mailbox microprocessors that can be accessed from two servers and VMEbus that provides the interface between processors to express that the mailbox has the ability to interrupt when VMEbus accesses the microprocessor. Interrupt handler - Interrupt handler and can be programmed to respond to any or all signals VMEbus IRQ * All normal processes VMEbus are related interrupts can be mapped to PCI INTA or SERR interrupts. These measures include: mailbox interrupt VMEbus interrupt VMEbus interrupter IACK cycle (confirm the interrupt sent by VMIVME-7697 VMEbus). All VMEbus related error handling can be mapped to PCI INTA # or SERR #. Note: PCI SERR starts SBC NMI. These measures include: ACFAIL * Interrupt BERR * Interrupt SYSFAIL * Interrupt interrupt handler has corresponding status/ID is registered for each IRQ * interrupt. Once the processor receives the message in IRQ *, it requests VMEbus. Once authorized, it will perform the following operations: IACK loop at this level. Once the IACK cycle is completed, the status/ID is stored in the corresponding ID register to set the appropriate interrupt status bit and generate a PCI interrupt. This PCI interrupt can be mapped to PCI INTA # or SERR1) selection of input/output points

It is necessary to clear the I/O points of the control system first, and then reserve 15~20% of the actual required points (leaving room for system transformation, etc.) to determine the points to be PLC.

The output points of PLC can be divided into common point type, grouping type and isolation type. Different voltage types and voltage levels can be used between groups of output points of isolated type, but the average price of each point of this PLC is higher. If isolation is not required between output signals, PLC of the first two output modes shall be selected.

(2) Selection of storage capacity

The user storage capacity can only be roughly estimated. In the system that only controls the switching value, it can be estimated by multiplying the input points by 10 words/point+the output points by 5 words/point; Counter/timer is estimated by (3-5) words/piece; (5~10) words/quantity for calculation processing; In the system with analog input/output, it can be estimated according to the storage capacity of about (80~100) words for each input/(or output) analog; In case of communication processing, the quantity of more than 200 words per interface shall be roughly estimated. After that, an allowance of 50-100% of the estimated capacity is generally reserved. For inexperienced designers, the margin should be larger when selecting capacity.

(3) Selection of I/O response time

The I/O response time of PLC includes input circuit delay, output circuit delay and time delay caused by scanning mode (generally 2~3 scanning cycles). For the switch control system, the PLC and I/O response time can generally meet the requirements of the actual project, so I/O response can be ignored. But for analog control system, especially for closed-loop system, this problem should be considered.
