In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

The learner will understand the operation and configuration of various types of PLC output modules and how they're used.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

In this animated object, learners examine how a Hall-effect sensor operates. A short quiz completes the activity.

Learners examine the three steps of a processor scan cycle.

In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.

Learners examine the functions of the three types of memory used by an Allen-Bradley SLC-500 programmable logic controller: the Executive ROM, Scratch Pad, and Processor File.

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.

In this animated object, learners examine the operation of up-counters and down-counters for a programmable controller. A brief quiz completes the activity.
