（6）据是否联网通信选型Orb305 product specifications this year is the third year of hicool Global Entrepreneur Summit. This summit takes "entrepreneurship meets innovation" as the theme, adheres to the "entrepreneur centered" concept, and creates a high-quality "Global Entrepreneur Carnival". By gathering more than 320 exhibitors and opening more than 20 characteristic activities, the summit has gathered more outstanding innovative and entrepreneurial talents, built a full chain entrepreneurial ecosystem, and fully served the growth of entrepreneurs. Innovation is an important part of ABB's DNA, and it is also the driving force for abb to serve customers all over the world and in all industries for more than a century. " He then reviewed ABB's innovation highlights of more than 130 years with the participants in the form of video. With milestone after milestone of innovative technology, abb stands at the forefront of all previous industrial revolutions and promotes the birth, evolution and development of many industries. Abb is committed to promoting social and industrial transformation and achieving a more efficient and sustainable future. Technology is the main driving force of green transformation: the widespread use of renewable energy, the continuous optimization of energy efficiency, and the accelerated application of electrification, digitalization and automation intelligent technologies - these have become the key to a more sustainable future. China is the world leader in the scale and growth of renewable energy installations. Over the past decade, China's total installed capacity of renewable energy power generation has increased by about 90 times, reaching 1.1 billion kilowatts by the end of 2021. As the world's leading innovative technology supplier of renewable energy, abb provides comprehensive solutions for photovoltaic power generation, wind power generation and energy storage power stations, and accelerates the industry's low-carbon and efficient energy transformation through digital upgrading of power distribution. In terms of optimizing energy efficiency, the biggest impact ABB can make is to help reduce energy use in industry, construction and transportation through leading technology - these fields account for nearly three quarters of global energy consumption. For example, 45% of the world's electricity is used to drive motors for building construction and industrial applications, so improving motor efficiency can bring great energy saving potential. By the end of 2021, abb had delivered more than 11 million frequency converters and high-efficiency motors to Chinese users, saving more than 500 billion kwh of energy. In the field of intelligent manufacturing, according to the latest global data, China installed more than 168000 industrial robots in 2020, setting a record for the number of robots installed in a single country. ABB has played an active role in this process, and at the same time, it continues to promote the robot to be more intelligent, powerful, simple and easy to use, more energy-saving and environmental friendly. ABB Robot super factory will be put into operation in Shanghai later this year to better meet the rapidly growing market demand. Transportation is another major contributor to carbon emissions, and electric transportation is the only way to achieve clean development. Abb is active in the entire value chain of electric transportation. Its main product portfolio includes electric vehicle charging solutions for cars and buses, traction systems for railways, trucks and mines, and Azipod for ships ® Propulsion system and green hydrogen technology. In the field of electric vehicle charging infrastructure, abb recently increased its majority stake in Shanghai ABB Lianzhuang. This month, ABB's electric transport China headquarters settled in Shenzhen, which will better meet China's fast-growing market demand. "Talent is the key to innovation. ABB cooperates with more than 100 universities worldwide. In China, supporting education is also a long tradition of abb." Kang Liang said, "we have cooperated with dozens of domestic universities and vocational colleges to build joint laboratories, hold technical seminars, and provide training resources. For example, we have supported the growth and development of innovative talents and entrepreneurial teams through the abb cup intelligent technology innovation competition and ABB electrical innovation challenge." In the face of the growing impact of climate change, sustainable development is more urgent than ever. As the world's second largest economy, China plays a vital role and has set a grand double carbon goal. 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 jointly create a sustainable future. " The "Empowering future" project launched by the "Global CEO committee" aims to pool resources, increase talents and build 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. In September last year, under the framework of "enabling 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 the VMEbus expression mailbox that provides inter processor interface has the ability to interrupt when VMEbus accesses the microprocessor. Interrupt handler - an interrupt handler and can be programmed to respond to any or all signals VMEbus IRQ * lines all normal process 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 to 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 to register each IRQ * interrupt. Once the processor receives the message in IRQ *, it requests VMEbus, and 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, the appropriate interrupt status bit is set, and a PCI interrupt is generated. This PCI interrupt can be mapped to the selection of input / output points by PCI inta # or serr1)
the I / O points of the control system shall be cleared first, and then the standby amount shall be set aside according to 15-20% of the actual number of points required (leaving room for system transformation, etc.), and then the number of points required for PLC shall be determined.
the output points of PLC can be divided into common point, grouping and isolation. Different voltage types and voltage levels can be used between each group of isolated output points, but the average price per point of this PLC is high. If isolation is not required between output signals, PLC with the first two output modes shall be selected.
(2) selection of storage capacity
the user storage capacity can only be roughly estimated. In a 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; The counter / timer estimates according to (3 ~ 5) words / piece; (5 ~ 10) words / quantity when there is arithmetic processing; In a system with analog input / output, it can be estimated according to the storage capacity of about (80-100) words per analog input / (or output); When there is communication processing, it is roughly estimated according to the number of more than 200 words per interface. After that, a margin is generally reserved at 50-100% of the estimated capacity. For inexperienced designers, it is better to leave more margin when selecting capacity.
(3) selection of I / O response time
I / O response time of PLC includes input circuit delay, output circuit delay and time delay caused by scanning mode of operation (generally 2-3 scanning cycles), etc. For the switching value control system, the response time of PLC and I / O can generally meet the requirements of the actual project, so it is unnecessary to consider the I / O response problem. However, for analog control systems, especially closed-loop systems, this problem should be considered.
(4) type selection according to the characteristics of output load
different loads have corresponding requirements for the output mode of PLC. For example, transistor or thyristor output type should be selected for inductive load with frequent on-off, rather than relay output type. However, the relay output PLC has many advantages, such as small conduction voltage drop, isolation function, relatively low price, strong ability to withstand instantaneous overvoltage and overcurrent, flexible load voltage (AC and DC) and wide voltage level range. Relay output type PLC can be selected for AC and DC loads with infrequent action.
(5) selection of online and offline programming
offline programming refers to that the host and the programmer share a CPU, and the programming, monitoring and operation status of PLC are selected through the programmer's mode selection switch. In the programming state, the CPU only serves the programmer and does not control the field. Online programming means that the host and the programmer each have a CPU. The CPU of the host controls the site, communicates with the programmer at the end of each scanning cycle, and the programmer sends the modified program to the host. In the next scanning cycle, the host will control the site according to the new program. Computer aided programming can realize both off-line and on-line programming. Online programming requires the purchase of computers and the configuration of programming software. The programming method shall be determined as required.
(6) according to whether networking communication is selected
