Interlocking Ladder Diagrams
Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.
Learners consider the correct type of pushbutton to use as a Stop button, the way the Stop button should be hard wired, and the PLC input instruction to use. This animated object includes a short quiz. It is recommended that learners review the learning object “The PLC Examine-Off Instruction” before beginning this object.
