Practical Tips and Techniques
Do-More Designer software features a fully functional simulator that can be used for teaching PLC programming. This software is free of charge.
You’ve had this idea for years since you were a kid. You want to be an electrical engineer, and you’re finally going to follow through on it and learn PLC programming to start your career off right! What? That’s what you thought, anyway. But then you started googling around, trying to figure out how to … Read more
Logic circuits in a PLC ladder logic program are either on or off. The inputs change, which will affect the outputs. This can be expressed in a timing diagram. The timing diagram or chart will show you how the ladder logic program will respond to the changing states of the inputs and outputs. This visual … Read more
The EasyPLC machining center loading robots will demonstrate sequencing and robot control using a PLC. Two input lines feed blanks to the robot. The robot will alternate taking the blanks and putting them into the CNC (Computer Numerical Control) machine. The robot moves the piece to the finished conveyor when the part has been machined. … Read more
PLC ladder logic counters are used in just about every PLC program. They will indicate how many times something has happened within the controller logic. Counters then can be used to trigger other outputs or items in the PLC. You can find counter applications in a variety of things every day. We will discuss three … Read more
Normally open (NO) contacts or inputs in the PLC ladder logic program do not mean the same as a wired normally open switch. NO contacts on the ladder logic provide the logic condition for the rung to turn on the output. We will be looking at three things about the normally open (NO) contact on … Read more
A rock crusher (jaw crushers) is also known as “rock breakers” and is used to break up larger, more complex materials into more manageable pieces. The EasyPLC simulator rock crusher plant will show you how you can control this process through a programmable logic controller. We will be using Do-More technology to control this plant … Read more
