Programming With Step 7 (1): General Configuration

Programming With Step 7 (1) : General Configuration

Simatic merupakan PLC buatan Siemens dimana banyak memilki varian seperti  s7-200, s7-300 dan s7-400 atau s7-1200. Untuk melakukan pemrograman PLC untuk jenis S7-300, S7-400 ke atas  hanya bisa dengan menggunakan Step-7. Sedangkan untuk S7-200 menggunakan software developer Microwin. Untuk tulisan kali ini saya akan membahas konfigurasi Step 7 untuk CPU S7-300 karena konfigurasi PLC untuk S7-300 dan S7-400 sama.

Biomass, What Is It

The Biomass Energy is the energy which is made by the organic material such as plants. This energy resources is very environment-friendly. In the high level country, this energy is developed and implemented. However, in Indonesia which has many areas of plantations and forest ththis has not be reserached further yet. It is very sad because Indonesia truely has big propect in this energy resources.

Recent Biomass Technology

The Biomass for power generation was reserached. There are many way for generate the electricity power use the organic materials. Furthermore, the performance of each system was searched base the scientific research. Poster below says about the technology which can be used for generating electricity power by biomass. You can read, Boiler - Anaaerobic - Gasification - Pyrolysis, are some of the way can be implemented. Although all of those technology have some positive and negative effect for daily life but we have to support this technology development. We hope the future biomass technology can be designed as green as possible.

So the choice of system for the biomass you have, choose depend on your environment and other condition. This is the one way to keep our world by using the biomass energy.

Energi Tidal, What Is It

We know that Indonesia is the archipelago country. It has many sea and other kind water area. In its national song, " Nenek Moyang ku Seorang Pelaut ", says that the origin people of this country is the sailor.  This condition gives the many advantages for Indonesia people especially in energy resources. That because the water can be power energy generation resource which can be used easily and cheap. Although the installation and building of the system need many money but the its feasibility is high for future life.

Energy Tidal is the energy from the change level of ocean. It is very easy to be implemented but its not famous like the other renewable energy sources. However, there is believes that this can be build in Indonesia although the investment for this plant is very huge. Furthermore, some of country over the world have built this plant then this performance is not too bad. We hope that the reserach about implementation of this power generation plant in Indonesia can be explored deeper so the possibility of building this plant can be count scientificly. There is some hopes!!!

 

Wind Turbine, How It Works

The Wind Turbine uses thye wind mechanical energy to generate the electricity power. For the high speed wind area, it has high prospect but for the low speed wind area, it doesnt. Whether it has high or low prospect, the important thing about this power generation machine is its environment friendly caharacteristics. For Indonesia, it is usefull for the remote area where the electricity company dont give any investment for electricity trasmission to  there. Especially for place such as the beach area  or island, it has the prospective feasibility.  

In recent news, this technology usually is installed together with solar cell/photovoltaic and genset. It gives more feasibility for this technology especially if the presence of solar light or high power wind is not stable. This system is called by Hybrid System. In some places, this system is implemented and it works well.

We hope the larger implementation is done so the environment can be saved from the conventional power generation which use oil and gas. You can share this poster use the original file (in extension .cdr) which can be reached by contact us. This is power for our green world!!!

Photovoltaic Answer to its Issues

There are many issues about the negative and positive effect of photovoltaic application in our daily life. All of these issues build some effect to some people over the world. If that effect give the advantage, that's no problem, but if it will give more bad damage, it will be dangerous for more people over the world.

If people over the world hear about the negative issues about photovoltaic and they avoid about implementation of photovoltaic in their daily life, the improvement of this technology will be shut in and the we will back to use the crude oil, coal or natural gasses as main power generation. All of that will give more big negative impact to our world and our lives.

So, we have to get the true side about the photovoltaic both negative and positive side. Then we can take the decision objectively about the photovoltaic implementation in our areas. This poster will do it because this poster is the result of reserach in the match literature and journal.  For the larger distribution you can share this poster with the original files from us (in .cdr format). We hope our environment will be saved!!!!

 

Photovoltaic, What and How

Who are know about photovoltaic? I believe majority of you knows that. The limitation of un-renewable energy (such as crude oil, natural gasses etc) source is problem for people over the world. Now, we are trying to use other energy source which can be renewed easily and in short time. Many energy source are provided in our surrounding, and the engineer and scientist considered all of those. Wind, water, solar etc are the renewable energy source met in our daily life. Thus, this photovoltaic use the solar light as main of power generator for producing electricity energy.

Easily, photovoltaic is made by semiconductor material consisted of non-stable electron structure (III-A and V-A group materials). Because of that structure, the electron can be easily moved because of solar light collision. That moves produce electricity power.

The poster below is made by me when I was student in bachelor degree. This poster is published in my laboratory information board. This gives information about basic of photovoltaic system and its application. This poster was made by software Corel Draw X13. If you need the original sources in extension .cdr, you can emailed me.
