The Core Programming Concept – break: The “Emergency Brake” in Loops, Stop When You Need To! Introduction: Young makers, we just learned how to use <span>continue</span> to make the loop “skip” a round and take a break. But sometimes, the situation is more urgent — we need to make the entire loop stop immediately! For … Read more
In traditional control circuits, such as forward and reverse control, star-delta starting, etc., the start, forward, and reverse buttons used in these circuits are all normally open contacts, while the stop button uses normally closed contacts. However, after learning about PLCs, you will encounter a question: Should the stop or emergency stop button of a … Read more
In PLC programming, the physical contact of the stop button is generally connected as normally closed, while in the program, it is written as normally open. This type of stop button only serves as a signal in this equipment.Why is the emergency stop in PLC programming opposite to that of a regular emergency stop button? … Read more
ABB robots can disconnect the teach pendant connection in automatic mode without affecting the execution of the robot program (Note: Disconnecting the teach pendant in manual mode will trigger an emergency stop fault). 1. For the Omnicore control cabinet, the 3018-1 Hot swappable FlexPendant software option is required, and the specific operations are as follows: … Read more
