How to properly use Profibus plugs and termination resistors (2016-04-14 15:18:33) reproduced
Tags:profibus plug Termination resistor DP plug
Plug and termination resistors play a very important role in Profibus communication, they are very simple to use and do not have many complicated settings, but because of their simplicity, many engineers ignore the details in their use, causing many communication problems.1 The structure and simple usage of Profibus

Fixed pipe cards for PVC pipes. PVC pipe joints are equipped with supporting joints, with PVC glue sticking, elbows are bent with spring. Dark box, wire pulling box and PVC pipe with Gong fixed.6. after the PVC pipe is installed, the cables should be uniformly worn. The same loop wire should be put in the same pi
The following is an example of the adapter mode:
A can speak English, B can speak Chinese, and they cannot communicate with each other. Now C says, I act as your translator.
If you think of a as an interface and B as an interface, C is an adapter. If it can convert the language of a into the language that B wants, or convert the language of B to the language a wants, it is a one-way Adapter. If it can convert their language, it is a two-way adapter.
The following shows the UML diagram:
wrapper) fits the interface of a class into what the user expects.An adaptation allows classes that are usually not working together because of incompatible interfaces, by wrapping the class's own interface in an existing class.It should be easy to understand what adapter mode is when you look at this very obscure thing.OK, said a lot of nonsense, will Java us, in the end how to use the Java language to describe the adapter mode it? Here we use the example of the notebook to describe the adapte
1. What is DD-WRT?
For the sake of respect, it is necessary to give a brief introduction to the predecessor of the DD-WRT, The DD-WRT is a "third-party" firmware, used for Linksys WRT54G/GS/GL or other 802.11g wireless routers based on the Broadcom reference design. Because these routers use the Linux operating system, the manufacturer has released the source code of these firmware based on the GPL terms.
The first version of DD-WRT was developed base

Hardware firewils don't have to be expensive. For instance, Netgear and Linksys models sport sufficient features for a reasonable cost.
Hardware firewalls are not expensive. For example, the Netgear and Linksys modules are worth the money.Endurer Note: 1. NetGea
principle:Most wireless routers display the list of connected clients, along with their associated host names, in the DHCP assignment information in the management interface. The list of display host names is derived from the DHCP request packet, which is sent by the client to the router (because the router also acts as a DHCP server). Then, since the request for an IP address does not require authentication, any user who has access to the local network can execute, through its host name, you c
Compared to wired networks, wireless networks have freed us from the shackles of cable, bring us great convenience, at the same time we must also consider that, if not set, within a certain coverage, wireless network is open to anyone, on the one hand, may be easy for strangers to enter their own network, using our bandwidth, On the one hand, it may cause information leakage. Let's take a look at the security configuration in the wireless router today.
Let's start with the wireless router. Ther
