This year is a year of China's 3G boom. All three major operators are fully constructing 3G networks. At present, they have launched their own 3G products and services to varying degrees. As a 3G standard with independent intellectual property rights in China, the development of TD-SCDMA has attracted more attention. Henan, Fujian, Hainan, Jiangxi and other provinces have issued corresponding policies to support the development of TD-SCDMA. China Mobile will invest 58.8 billion yuan this year to

a well-defined extensibility mechanism. Learning from the experience of early Internet protocols, IMAP extensions define a clear mechanism. Many extensions to the original protocol have been proposed and widely used. Whether you use POP3 or IMAP4 to get the message, the client uses the SMTP protocol to send it. The mail client may be a POP client or an IMAP client, but it will use SMTP. Detailed overview component-based software tools for configuring communication in distributed automation solu

In the future, the most important ingredient will be smart data. That is why Siemens is investing in efficiency-enhancing technologies such as flexible service models and advanced PLM software. As these new digital business models become more powerful, they will transform Siemens into a true digital enterprise.Riyadh, the Saudi capital, has a population of about 6 million and is growing rapidly. In order to

systems, a complete and effective communication service model must be established based on Ethernet + TCP/IP protocol, and an effective real-time communication service mechanism should be developed, coordinates the real-time and non-real-time information transmission services in the industrial field control system to form the application layer and user layer protocols received by the majority of industrial control manufacturers and users, thus forming open standards.To this end, bus organizatio

Real-World challenges: Workflow based on Osgi/bndtools development, release, and Versioning The first article in the series introduced the fundamental relationship between structural modularity and agility, and in the second we learned how to use OSGi to implement highly agile and highly maintainable software systems. The third article is based on the title "Real-World challenges: workflows based on Osgi/bndtools development, publishing, and Versioning" (Workflow for Development, releases and

SIEMENS S5 PLC through a serial port. Supports the 3964R protocol and other Siemens devices that support this protocol.S_7: three methods are supported to connect the Siemens S7 PLC series, namely, PROFIBUS (L2), Industrial Ethernet (H1), and standard Ethernet (TCPIP ). The three connection methods are described as follows:PROFIBUS: supports the FMS and MPI prot

for this problem. DTD wireless 485 data terminal can be used to replace wired RS485 and RS232 for wireless transmission of digital signals. The wireless RS485 communication module is added to the PLC, and dtd433 wireless PLC communication terminal is used, which is equivalent to directly replacing the RS485 dual-line. It is easy to use without setting up. Communication distance covers 100 meters ~ 3000 meters. Topology Map of DTD wireless 485 data terminal replacing wired RS485: Three typic

for the National Semiconductor enterprise system. The reference design has the clock synchronization capability of less than NS and can be used in various applications. The precision of this level is critical to meeting the demanding communication latency and Quality of Service (QoS) requirements required by industrial connections. The target applications include Ethernet switches using Ethernet/IP, ProfiNet, EthernetPowerlink, and other Ethernet pro

Railways in the introduction of the time, I hope that long customers can introduce the most favored German Siemens ice, China Southern car Sifang AG because with Kawasaki, Japan has more than 20 years of partnership, so the Quartet to determine the introduction of Japanese technology.

He has been in the industrial control field for nearly seven years. Although the current study of embedded systems and industrial control are inextricably linked, but there is already some distance from the first line, I hope that in the future embedded research experience, but also back to the first line of industrial control automation. The following are some of the gains of industrial control over the years ...... I. Industrial Control Automation sharing software 1.

In the Internet era where this concept is prevalent, the cloud is a major concern. With the influence of the cloud concept, the cloud also appeared in the Unified Communication Service. How is the Unified Communication Service associated with the cloud? What is the difference between the Unified Communication Service under the cloud concept? "Because all resources are used to manage the Unified Communication platform, it is not a bad choice to choose hosting," said Vanessa Alvarez, an authoritat

In the previous article, we introduced SOA and unified communication, including its overall concept and traffic business. Now we will continue to explain SOA and Unified Communication. First, let's review the four methods of SOA in speech. Then, we will introduce the situation of some products and vendors. Four Methods of hybrid speech and SOA Despite the bright future, the market is still in its initial stage, with only four major vendors. Avaya and Siemens
