Logic to Ladder Diagram There are some methods to do PLC programming. The programming methods can be with Logic Ladder Diagram‚ mnemonic (statement list)‚ and / or function block diagram. One of the PLC programming methods that are very commonly used programming using PLC ladder diagram. The method is practical and easy to understand. The programmer in charge of writing a program should describe an electronic switch circuit. It can be designed to perform the conversion of electronic circuits that

THE LOGIC OF EXPERIMENTAL DESIGN The randomized comparative experiment is one of the most important ideas in statistics. It is designed to allow us to draw cause-and-effect conclusions. Be sure you understand the logic: • Randomization produces groups of subjects that should be similar in all respects before we apply the treatments. • Comparative design ensures that influences other than the experimental treatments operate equally on all groups. • Therefore‚ differences in the response variable
