PLC Twido Training with Schneider Electric Training Centre

At Schneider Electric Training Center, we are introduced how to use PLC, especially Twido PLC.

 

What is Twido?

TwidoSuite is a full-featured, graphical development environment for creating,configuring, and maintaining automation applications for Schneider Electric Twido programmable controllers.

A programmable controller reads inputs, writes to outputs, and solves logic based on a control program. Creating a control program for a Twido controller consists of writing a series of instructions in one of the Twido programming languages.

Twido Languages

The following languages can be used to create Twido control programs:

  •  Instruction List Language:

An Instruction List program is a series of logical expressions written as a sequence of Boolean instructions. A program written in Instruction List language consists of a series of instructions executed sequentially by the controller. The following is an example of a List program.


  •  Ladder Diagrams:

A Ladder diagram is a graphical means of displaying a logical expression. Ladder diagrams are similar to relay logic diagrams that represent relay control circuits. Graphic elements such as coils, contacts, and blocks represent instructions.The following is an example of a Ladder diagram.


  • Grafcet Language:

Grafcet language is made up of a series of steps and transitions. Twido supports the use of Grafcet list instructions, but not graphical Grafcet. The Grafcet analytical method divides any sequential control system into a series of steps, with which actions, transitions, and conditions are associated. The following illustration shows examples of Grafcet instructions in List and Ladder programs respectively.

LAPAN Build 48 Windmills in Pandansimo Beach

Sunday, March 20, 2011 Posted by Galih Eka Priminta , , , No comments

Coastal Bantul was selected as the location of the windmill, precisely in Pandansimo Beach, Srandakan Bantul regency, Yogyakarta. Windmill as much as 48 fruits that are targeted for completion in December 2010.
In addition to providing alternative energy, windmill construction is expected to attract more young people in Bantul for technological literacy. 

“They, especially for school children, will be more motivated to learn the benefits of technology can be applied to the advancement of regional development in Bantul district,” said Professor Samsa heads a team from the Ministry of Research and Technology (Research and Technology), in den Regent of Bantul, Yogyakarta, Friday (08/27/2010). Samsa reveal this to the Regent of Bantul Hj. Sri Suryawidati accompanied by a team from the Indonesian Islamic University (UII). 

According Samsa, Bantul chosen as the location for the application of coastal-based wind turbine technology is expected to attract more school children for generations and prefer to learn the technology. Bantul so that later will be able to print more experts in the field of technology which can give greater benefits to improve people’s welfare. 

“We hope Bantul would be able to print more experts in the field of technology,” he said. 

Application of this technology, Samsa said, is expected to also be able to encourage the community to develop productive enterprises. The plan is every tourist areas will be equipped with technology that complemented the corner all the ins and outs, so it will attract tourists to learn more technology.

“It will also be the potential for tourism, in addition to existing tours at sea,” he explained 

Bantul Regent Hj. Sri Suryawidati in his remarks convey his gratitude to the team, especially from the Ministry of Research and Technology who have given their belief that the Bantul area a site of technological development that is needed by this wider community.

“This is certainly going to be more complete because of Bantul, Bantul now included as one of the recipients of science and technology in 2010 grace the national level,” he said 

During the visit one of the team also said that the current location of Bantul is projected to become earthquake-resistant construction of a model home located in the subdistrict Pandak. Model homes can be built with the former building materials are very cheap cost approximately Rp1 million per square meter. This plan will also be disseminated prior to the builder as Bantul.

Getting to Know Geothermal Based Power Plants

Sunday, November 07, 2010 Posted by Galih Eka Priminta , , , , , 1 comment
 Indonesia has a very large geothermal potential, which is mostly underdeveloped due to several obstacles.  This has not deterred the government’s attempt in maximizing  available potentials by addressing these obstacles.


With the large amount of available potentials, Indonesia will not only able to fill its electricity demand, but also has the capability to export geothermal-sourced electricity.  Indonesia’s current geothermal potential equals to 28 GW, of which only 1189 MW (4%) has been harnessed.
