Before I get to work. The programming is very important to me. If you have a PLC with the PLC, its modules and run power equipment industry. You must complete the nobility of the modules in the PLC program you have it
You know, for example analog modules or the knob to the START step and what are defined in the PLC program
I'll keep it simple for you to be absolutely clear. In this example the result of my experience when working with PLC S7-300 obtained.
I plan to fast CW CCW PLC S7-300 314C-2DP with STL in writing.
We know that in practice, because most engines are under pressure to change the motor round suddenly. But this is an engine without a load test.
If you write a program to CW and CCW immediately in the next line, write the program in Simulation software STEP 7 will not cause any problems.contactor can not right now, and for a moment to collide and fuse the two phase jumps.
The results of this example is that we try where possible to write programs that are close to reality. The best way to work with PLC hardware with the software.
If you do not have access to hardware resources can be used where the assignments.
The most important thing you need is love.
As I told you in the field of vocational possibilities PLC is excellent. I myself for 5 months in the grade 2 and grade followed by LC with PLC S7-200, S7-300, school boards ELWE German company, set up with all kinds of motors, PLC, a network of 300 Siemens PLC, different models of mini- The LCD like Zelio, Logo, Easy and. . . Actually worked. But most of the information in the above issues and Win CC, followed by LCD LG, sensor types, followed by Delta and LCD. . . I owe my passion, perseverance, read different books, research on the internet and most importantly, working in an environment where I'm dealing with the PLC. I still think that way myself.
I think the best reference for the Internet. If the book can also access the site to learn more and deeper.
PLC is a wonderful world. I think it is better to choose a category from the field study.
After a while you will see that the PLC are somewhat similar.
There are people who can help you in this area through the Internet. If the menu is also a member of this big family happy you did.
