fieldbus communication

The second part, as mentioned in the previous issue of synergy, although the framework is slightly clear, the process has targeted adjustments, but in the process of doing things, how people deal with or success or failure of the determinants. Good things because bad communication can become very bad, leading to deviations in direction, and bad things due to bad communication may become very "good", hiding

Single-chip microcomputer and (serial screen) touch screen communication based on Modbus Protocol (graphic)Introduction: Touch screen can be intuitive, vivid display of operating parameters and operating state, and through the touch screen screen can directly modify the system operating parameters, human-machine interaction is good. Touch screen and single-chip communication, the need for a single-chip micr

Serial Port is short for serial port, also known as serial communication interface or COM interface. Serial communication refers to the communication mode that uses the serial communication protocol (Serial Communication) to transmit data from one bit to one bit on a signa

In the design of all kinds of SCM application system, often encountered SCM and PC communication problems, in the speed is not high, the transmission distance is not far from the general use of RS 232 standard serial interface to achieve, in the transmission distance from the occasion, there are scholars to study the network to achieve communication between the PC. However, it is an urgent problem to meet b

Inter-process communication is the transmission or exchange of information between different processes, so what is there between the different processes that can be accessed by both parties? The user space of the process is independent of each other and is generally inaccessible to each other, with the only exception being the shared memory area. However, the system space is a "public place", so the kernel can obviously provide such conditions. In add

The use of microwave communication with large capacity, good quality and can be transmitted to a very long distance, it is a national communication network of an important means of communication, but also widely applicable to a variety of special communications network. Microwave communication in China is widely used

OrderThe process communication methods under Linux are basically inherited from the process communication methods on the UNIX platform. The two main players at T-Lab and BSD (UC Berkeley's Berkeley Software Release Center), which have made significant contributions to the development of UNIX, have a different focus on interprocess communication. The former makes

This is the "PLC wireless communication expert" team to provide users with a Siemens S7-200PLC communication program, the user needs to carry out the Modbus protocol communication between the 9 s7-200, he is not familiar with the communication, in order to deliver the project as soon as possible, ask our engineers to w

The process communication methods under Linux are basically inherited from the process communication methods on the UNIX platform. And the two main at that make a major contribution to the development of UnixT's Bell Labs and BSD (UC Berkeley's Berkeley Software Release Center) have a different focus on inter-process communication. The former is a systematic impr

Understanding Serial Communications There are many kinds of serial communication protocols, such as rs232,rs485,rs422, or even the current popular USB is serial Communication protocols. And the application of serial communication technology is everywhere. Maybe everyone sees the computer serial and mode. M's communication
