Editing Programmable logic controller (section)

===Simulation===
An incorrectly programmed PLC can result in lost productivity and dangerous conditions for programmed equipment. PLC simulation is a feature often found in PLC programming software. It allows for testing and [[debugging]] early in a project's development. Testing the project in simulation improves its quality, increases the level of safety associated with equipment and can save time during the installation and commissioning of automated control applications since many scenarios can be tried and tested before the system is activated.<ref name=":7" /><ref>{{cite book |last1=Lin |first1=Sally |url=https://books.google.com/books?id=CHYlTBxqrM8C&pg=PA553 |title=Advances in Computer Science, Environment, Ecoinformatics, and Education, Part III: International Conference, CSEE 2011, Wuhan, China, August 21-22, 2011.
