How to Change the MPI Node Address For a Siemens S7-300 PLC

I have seven Siemens S7-300 PLCs connected together using the MPI (Multi Point Interface) interface. The Siemens MPI protocol is used by Siemens PLCs to communicate with external devices. I want to rename each of the seven PLCs. Here are the steps to accomplish that task.

First, connect your MPI cable to the first PLC. I will be connecting my laptop to each PLC individually. Power up the PLC and open Simatic Manager. The "New Project" Wizard window will open. Just click Cancel to close the window. Now click the Accessible Nodes icon on the toolbar. A window will open showing the identification of the PLC you are connected to. My window is showing MPI = 2 (directly). Make a note of this address and close the window.

Next we need to download a hardware configuration to the PLC. This is where we will rename the PLC node address. There are probably a couple of different ways to do this – following is how I accomplish this. All seven of my PLCs are the same model; Therefore, I am using the same hardware configuration. For the obvious reasons, I want to give each a different MPI node address. I have a project file that contains all seven of my PLC programs and one hardware configuration file. I open the one hardware configuration file, and then double click Hardware in the right hand window. This will open the HW Configuration window. In this window you should see your PLC with its MPI address given.

Remember when we clicked the Accessible Nodes icon and saw MPI = 2 (directly)? My Hardware Configuration Window is showing a MPI address of 7. Place your mouse cursor on the 7 and double click. Your CPU Properties window will open. It should open to the General tab. Look down and you will see Interface Type MPI with an address of 7. Click Properties and the MPI interface Properties window will open. Using the pull down menu, choose your MPI node address and make sure the MPI (1) 187.5kbps is highlighted and click OK. You are now back on the CPU Properties window where you will see your address has changed. Click OK and you will go back to the Hard Ware window where you can verify your MPI node address has changed.

You will now click the Save and Compile icon and then click the download icon. The Select Target Module window will open. Click OK and the Select Node Address window will open. Here you will see the MPI node address you assigned earlier. You will need to click the View button right below this. You will see the current node address appear, this should be the same as what you saw earlier when you clicked the Accessible Nodes icon. Simply click on this number and you will see it appear in the MPI address slot under the Enter connection to target station. Click OK and the Download to Module window will open. Click OK and the Stop Target Modules window will open. Click OK and the "Do you want to start the module?" Window will open. Click Yes.

Now go back to the SIMATIC Manager window and click the accessible nodes icon. You will see your new MPI node address. You can see this same article with pictures at http://www.morerobototics.com .

Strengths and Weaknesses of Waterfall Approach for Software Development

One of the most famous and widely used approaches for software development is the waterfall model. Waterfall approach is an old technique that has been in use for quite some time, but in modern times agile approach is gaining prominence.

Waterfall approach, as is evident from the name, refers to a systematic approach where one step comes after the other. It cannot go the other way round. The process works like the waterfall effect that flows in one direction, which is from up to down.

In this process the life cycle of the development process is predetermined. All the steps are defined before the start of the project. The approach is predictive, where the team is well aware of the order of each step and therefore works accordingly. It starts from the requirement analysis, the design phase and then proceeds on to the implementation, testing and the maintenance phases.

The waterfall approach can be quite beneficial for those who are quite clear on their requirements. A planned approach works for them because they want fixed processes and budget. Where fixed processes are beneficial, at the same time they can be inconvenient at times. In cases where the client is not clear on the requirements and finds in the middle of the project that he/she wants to change course, this approach can prove to be quite problematic.

Another point of the waterfall approach is that the requirement analysis and design of architectural structure can consume a lot of time. Extensive research is done initially as the next phases depend completely on the planning strategy. However, the good thing is that everything is thoroughly worked out and each aspect is studied beforehand. The developers in such cases know what is expected of them.

A waterfall approach works in a systematic order, with one step following the other and the testing phase comes in the end. If there are any big problems encountered in the testing phase, it means a long process to make the amends. The process can consume extra time and money.

We cannot conclude that one approach is better than the other, as every method would have its own strengths and weaknesses. The determination of success for each method depends on how it is being used and whether the approach suits the scope of work being undertaken. While one approach may be suitable for a particular project, it might become totally useless under different circumstances. For example, some believe that agile methods are not well suited for offshore development, as they require a closer contact and communication that is not possible in an offshore project.

Why Computer Hardware Is Important

In this day and age, it is hard to deny the influence of technology in our lives. We live in an era where pretty much is automated and computerized. And amidst all the technological advancement that humankind has achieved, one important device has been created that will only sure to become more relevant to our lives as technology progresses, the computer. No one can deny that computers are now an essential part of our lives, the same way a cell phone and television does. It is safe to say that in this day and age, having no computer would be an inconvenience. Which is why it is important that we know the way our computer works so that we would be aware of the things that we should do in case it stops working. The hardware of the computer is considered to be the most important because without it, it will simply not work.

Simply put if you know how to handle the hardware of a computer and know each of their function for the unit, then you can easily determine what the problem is in case the unit stops functioning. In order to be familiar with basic computer troubleshooting, then you also need to be familiar with computer hardware. A good example of this is the memory of the computer (RAM). All programs and applications that are ran in a computer needs memory. Without RAM it simply will not function. Aside from that, even if you have a RAM but it does have the specifications to keep up with the programs that are being run, then the operation would have slowed down to a crawl. So when it comes to computer hardware, you have to make sure that it is not obsolete, so you need to upgrade depending on what sort of program that you are usually using.

When handling computer hardware, you have to keep in mind some safety measures so you can manipulate the unit safely. Before opening any computer cases, you have to make sure that the unit is unplugged or you might risk electrocution or shocks. While checking your hardware components, always check for damaged parts because that is most likely the one that is causing problems. When inserting components and parts, you have to remember that if it does not fit, then most likely you are inserting it on the wrong slot. If it does not fit, then do not force it or you will risk breaking the component. Before touching any parts inside the unit, make sure that you discharge yourself first by through a grounded metal object or you can use an anti-static wrist strap or mat which is sold in stores for cheap.

By knowing and analyzing every computer hardware part you will know about its importance and if it ever breaks down then you can perform the proper troubleshooting steps. Every hardware component is important for the computer's operation. The performance of your computer largely depends on how good your hardware is, so be sure that they are always in good working condition.

Who Invented Dell Computers?

The invention and the history of the Dell computer is quite interesting. First of all, it was in 1984 when Michael Dell, a student at the University of Texas at Austin, created the company PC's Limited. He only had a starting capital of $ 1,000. So what he did was started working out of his dorm room to build personal computers made from stock components. These computers were to be IBM compatible because that was the standard at that time. If a computer were to function with various pieces of hardware, it needed to be IMB compatible.

It is when Michael Dell figured that selling computers directly to customers to determine customer need that he dropped out of college. His family then extended him the $ 300,000 in expansion capital that he needed to make his business take off.

A success

It was in 1985 that the Turbo PC was developed and it sold for less than $ 800. It contained an Intel 8088 processor that ran at 8 MHz, which is significantly slower than the computers that we use today. Computers today are running in gigahertz, which are hundreds and even thousands of times faster than the 8 MHz processor that Michael Dell was installing in his computers at the time. But the truth is that this was the best that could be done in 1985. The technology was developing.

But there was an aspect of PC's Limited that was unique from the rest and continues to be this way today. It is the fact that customers could order their computers rather than buy a computer that was already assembled. This allowed individuals to receive computers at lower prices than what they could get with their competitors. This definitely worked because PC's Limited grossed $ 73 million in its first year of trading.

The beginning of Dell

It was in 1988 that PC's Limited became Dell. Prior to that, the company already had 11 international operations occurring, so the company was quite large. There were on site services set up to compensate for the lack of businesses acting as service centers for Dell computers. It was in 1990 that Dell attempted to sell through club houses, but had very little success with this. So it is then that Dell went right back to its direct to customer sales.

In 1996, Dell started selling computers on its website. An individual could go onto the website and custom design their computer so that it would be built to their specifications. From there, it would be shipped to the customer's home. Financing was made available so that individuals would be able to acquire their computers easily.

In 1999, Dell became the largest personal computer seller when they took over Compaq computers. Their revenue topped $ 25 billion in 2002. Also in 2002, Dell started selling televisions and other electronic items. They now have Dell brand printers, LCD TVs, and much more. Because of the expansion beyond computers, Dell was changed to Dell Inc. In 2003.

It is amazing that this billion dollar company started in a dorm room with $ 1000 in starting capital. And Michael Dell has always stood by the principles of letting individuals have the capability to design their own machine. Although there are Dell computers now sold in various retail outlets, a person can still go to the website and design the machine of their dreams. And Dell also offers a lot of assistance for individuals needing help with their computers. They offer on-site services and so much more for the computer user so that they can have the best experience possible.
