Fault types that can be solved by the RF restart Command Group in a Programmable switch
The restart command can solve the following fault types:
First, the software operation failure is caused by some interference of the switch;
Second, when the switch system enters the maintenance application stage, the maintenance operator's maintenance level is faulty or the fault is caused by some misoperation of the user;
Third, the impact of environmental factor
FPGA is short for field programmable gate array (Field Programmable Gate Array). It is a product of further development on the basis of PAL, gal, PLD, and other programmable devices, is the most integrated type in specialized Integrated Circuits (ASIC.

1. IntroductionIn recent years, with the rapid development of communication technology, network technology and semiconductor technology, the design of intelligent instrumentation System has entered a new era. Among them, the realization of Internet access is the current development of intelligent instrumentation System hot field and important direction.The ISP (in System programmability) is of great significance for the realization of the Internet access of intelligent instrument system based on
most traditional and common access method. The diameter of the copper wire transmitted by the local telephone is generally 0.4mm. To ensure audio transmission, generally, the user line cannot exceed 5 kilometers. Therefore, the next Programmable switch in the traditional copper access mode can cover a region with a radius of 5 kilometers. Generally, the wiring method is used for hand-over. A user cable is generally provided by a program-controlled sw

If the HTML document does not have an HTML syntax explanation, it is a plain text document. It is a common string. if you add the HTML syntax to this string, this plain text document immediately becomes a structured document with considerable complexity. In the same way, plain text documents such as XML files and SQL statements are a common string before they are interpreted. After being interpreted
: interrupt mode. Normally, no other interruptions occur in this mode. However, there are exceptions. Some CPUs classify the interrupt priority, and higher-priority interruptions may occur. This means that the first-level interrupt processing code must be carefully written, and the interrupt processing process should have its own stack, this allows you to store the CPU execution status (General registers and context of all CPUs) before the process is interrupted ). Some CPUs have a set of specia
PLC commonly used programming language:There are many programming languages in the programmable controller, they are ladder diagram language, Boolean mnemonic language, function chart language, function module diagram language and structured statement description language, etc. Ladder language and Boolean mnemonic language is the basic programming language, which is usually composed of a series of instructions, which can accomplish most simple control
The Programmable switch is still quite common. So I studied the comprehensive Lightning Protection Problem of the programmable switch. Here I will share it with you and hope it will be useful to you. Currently, many organizations have installed programmable switches, and the main component of the programmable switches
