Industrial Ethernet: The Hunt for the CSMA / CD

The unexpected nature of Ethernet TCP / IP s time ‘has long been a weakness for many industrial network applications, especially those with real-time requirements rugged capabilities. However, due to the overall cost vs. performance benefits has increased over time, industrial users have developed a way to overcome the obvious shortcomings.

In total, there are currently about thirty Industrial Ethernet system used around the world, but these are the most significant North American market are:

Ethernet / IP

Modbus / TCP

EtherCAT ®

Ethernet Powerlink


All protocols developed with the challenges of real-time control thinking (constant rotation time, low latency, low jitter), this particular design preventive measures to avoid collision data, and they approach the solution in different ways.

The a real difference to the standard Ethernet TCP / IP is a further implementation of the Real Time Data Exchange module that manages real-time communication in either place or on top of TCP / IP / UDP.Still, all protocols continue support for Ethernet (IEEE 802.3 layer) and physical data and TCP / IP / UDP, thus providing an interface to networks.

Protocols standard level information such as Ethernet / IP and Modbus / TCP seems most vulnerable when it comes to hard real-time control, for they will inherit all the features that make the Ethernet TCP / IP non-deterministic. While the CSMA / CD edition (random time delay after bus arbitration) can be significantly reduced by using Ethernet switches, protocols still face the additional jitter caused by the UDP and IP. Without careful design considerations, they were questioned for hard real-time control, especially for fast applications.

Ethernet Powerlink motion control circumvents the CSMA / CD problem very elegantly passing through TCP / IP / UDP layer when it comes to real-time communication. Ethernet Powerlink uses a focused and highly deterministic time slice assigned to each node in the network. The result is that only one node sends data on the bus during a dedicated time slice, while all other nodes wait for their turn. This procedure effectively prevents any message collision and thereby eliminate idle random times. Obviously, via TCP / IP / UDP also removes the IP / UDP jitter.

EtherCAT ®, however, came the CSMA / CD problem by removing completely the physical level, which, with all consequences time, requiring the use of dedicated hardware. While the EtherCAT Master ® system only requires common Ethernet network interfaces, each EtherCAT ® slave device requires a special controller. EtherCAT ® still using Ethernet as the physical layer, but the Ethernet message is passed from node to node (daisy-chain), thus eliminating the need for bus arbitration per CSMA / CD.

Profinet, compared to all other protocols introduced here, have a transition through all situations described earlier: PROFINET V1 (CBA) using standard Ethernet TCP / IP, PROFINET V2 (RT) bypasses the TCP / IP / UDP layer, while the PROFINET V3 (IRT) using a dedicated Ethernet controller.

Long-Tail Versus. Short Tail Keywords: Pros and Cons

Most experienced in the business of SEO still do not understand the basics of keywords. Most companies use a variety of keywords or short tail keywords in their internet marketing strategy. But many companies do not understand that there is a narrow keywords or long tail keywords can also be useful for SEO purposes. Understand the advantages and disadvantages for both long tail and short tail keywords can help your company create strategies.

Short-tail marketing KeywordsWhat short tail keywords better? This broad search terms people use when they are researching information on the internet.

When creating web content, it is important to make sure that the keywords used in the rest of the text flow. Fits the word “sleep” in the sentence is relatively easy. Make sure your keywords into your content is not difficult, but it will pay multi-fold due to Google’s new focus on quality and relevant content.

Cons KeywordsIf short tail short tail keywords attract a large audience, it is easy to write about and help marketers determine keywords relevant to a particular campaign, what could possibly be bad about that? One disadvantage of using keywords is that you can attract the wrong kind of traffic to your site. If your company sells dog beds do not want people who are looking for a bed that comes to your website. You want people who are looking for a dog bed, and maybe even people who are looking for a bed for older dogs. The more words you use in a search term, the more precise the results be.

Another against competition keywords. These words are popular with web surfers, so businesses want to buy it. It can ruin your PPC campaigns and can also make it difficult for you to get high search engine rankings. Type keyword is also useful for people who want to make a niche KeywordsLong campaigns.

Long-tail-tail keywords are also known as narrow a search term. It is a phrase that web surfers will enter into a search box when they are looking for something specific. Returning to the example in “bed”, web surfers can enter the term “beds for teens in New York City”. By entering a particular phrase, the web surfer will receive a list of websites that are relevant to people who are looking to New York City to buy a bed for a teenager, it does not get much a target of the short tail keywords long tail KeywordsIf that.Pros is something that a person will go when they are just starting a search, long tail keywords are phrases that people get when they are closer to making a final decision. The increase in conversion rate helps to compensate for the decline in the company’s web traffic.

Most not use these keywords when they create their website or when they formulate AdWords campaigns. So the added benefit of long tail keywords is that your company does not have much competition.

Cons Quality Long tail keywords KeywordsWhile types can help create targeted traffic to the website you and offers the advantage of less competition, there are some drawbacks.

How many times do you think you’ll be able to add the phrase on a web page and still make the overall flow of the content? Types of keywords are often complex and difficult to use in sales letters, and you do not want to appear as if you are charging and use keywords pronunciation difficult to cram just one keyword at a disadvantage article.

Another use of this type of keywords is really firm need to understand the market and the terms that are used to achieve the organization’s website. If the company is focused on the wrong keywords then they will not receive the right kind of traffic types of keywords can be useful for corporate internet marketing strategy.

Getting Used to WordPress

If you are someone who just started using WordPress, or maybe you come from a different WP CMS in the world, there are some things you may need to adjust to.

Here see a list of 5 things you probably WP every user should know about.

Vs WYSIWIG HTML. WordPress uses what is known as What You See is What You Get Editor. What this means, is the built-in editor that works like a word processor interface used to use when creating an email using Gmail or Yahoo mail or any time you type a letter to someone in your computer. Yes, you do not have the option to switch to the HTML editor (text) if you want to use, but for the most part, you use a WYSIWIG (pronounced “whizzy-wig”) or “Visual”; Editor.

Plugin. Out of the box, WordPress is a CMS that is very capable, however, there are some things you can not do with this application as it comes. That is where plugins step in. There are many different plugins for things like forms, SEO, image galleries and changing the functionality of WordPress. Some plugins require configuration, others are not. The thing to remember, is that if there is something you are trying to do and can not imagine if, maybe there is a plugin that will help you achieve.

Theme. Some people call it a template, but whatever you call them, these themes are what control the look and feel of your site. Changing the theme is as easy as just selecting the menu theme under “Appearance”. Installing the theme, as easy as clicking the “Install theme” tab, under Appearance> Install theme and then choose a new theme from the updated lists etc or do a search to the theme.

Self-host vs. host. Perhaps this is one of the biggest points of confusion. You always, always need hosting for your WordPress site. The difference is if you use a free hosting WP itself provide or pay for your own hosting account. If you are using a free hosting, you are limited to the type of themes and plugins that you can use, as well as the type of content you can post. You will also have a website with a “” address instead of “” address.

Hosting account. Talk hosting account, if you are self-hosting your blog, you need to buy hosting personal account. Currently, most of the webhosting provider that is supported by WordPress, so not really a problem. Some webhosts provide one click installation, and others want to install it manually. Just ask to see if the host supports one click install or not.

That’s 5 things you may need to get used to if you are planning to start a new website or blog using WordPress.

How to Earn $ 100 a Day With Free Content (No Gimmicks Needed)

I still believe that overall the easiest way to earn a full time income in 2013, 100% marketing.
Content online content marketing really can be anything that allows you to get your marketing message out to the masses … Way.
For use your content in a creative example, the number of days … I have personally written over 5,000 unique articles will make more than 4,000,000 new audience, in an article directory itself. Not the number of readers of my blog, e-mail or customer, or social media followers, or the hustle and bustle of other places I publish my content.
While not everyone is going to write an article 5000. .. You may have better results, much less work than I have.
For example, a good video on YouTube can generate hundreds of thousands of unique viewers, in a matter of weeks or months. (Some again … especially if your video goes viral, funny or controversial niche hyper) You can write an ebook on Amazon and really quite get tens of thousands of people read it, 00% for free … with very little promotion. (Amazon last book I have downloaded more than 5,000 times in 48 hours, and I have done very little to promote it, than to give it for free for the first 2 days) A PDF of the virus to the same effect, especially if you are solo ads, or JV partners to collaborate and work together with your content, or campaign.
Here is the secret to using your content to earn good money … basis.
First prepare every day, a small amount of content you … curriculum. (One thing you can teach, preach or offer for profit) OR – find a large number of affiliate offers that serve the same purpose. (Example – something that you can use your content in the “dot”, to develop an easy commission) Then, just use a very simple approach to a straight line on the channel traffic to your content DIRECTLY high number of curriculum or its affiliates offer.
For example, if you choose the affiliate offer high EPC (EPC definition, the average earnings per 100 visitors called) with a straight redirect, you can write an article as I explain below, and for every 100 visitors you refer to this program, you will make about $ 100. (As long as the traffic is doing, equivalent to the average affiliate) or – if you have your own “curriculum” or bid, you simply use the same traffic to send it to you instead. (The $ 100 personal coaching or mentoring program that will be converted into a 2 or 3%, which means that you only need 33-50 visitors per day on average $ 100) Finally, it’s all about love, the more profit.
