Thank you for reading the opening article about Ladder Logic. + You cannot create a branch that could cause a short circuit. + You cannot create a branch that can result in a signal stream in the opposite direction. Do not end a network with either a comparison command (Compare) or a command to detect a threshold (positive or negative threshold) + Each LAD network must end with a coil or a box command. The following rules when creating an LAD network:.Because ladder languages вЂ‹вЂ‹are very similar to relay circuits, people who know about electrical circuits can easily switch to PLC programming, here are 2 examples.When one of the 2 Inputs in the logical state is 1, the Output = 1 OR When both Input-1 and Input-2 have a logic level of 1, Output = 1 AND This is Browser toolbar for Attic Ladder,Attic Stairs,Egress Windows,use this to search ,you can also chesk the local weather with this toolbar If you are ever. Therefore, the Ladder Logic programming language is the best visual programming language for PLC.It is constantly being up ranked in the Top most popular programming languages in the world according to IEEE Spectrum Terminologies Conditions and Actions

So if you know the relay control circuit you will learn Ladder Logic programming very quickly and easily Ladder Logic programming language is characterized by looking very similar to electrical relay circuits. It is an extremely intuitive graphical programming language, easy to learn, easy to program and fix errors Ladder Logic Ladder Logic programming language is the leading popular programming language in PLC programming.
