In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.

Learners study an animated PLC counting operation and examine how the count is automatically reset.

Learners examine the counter-reset function of a programmable controller and how it is used.

Learners examine the sourcing and sinking of conventional current at a PLC output module and the type of field device to which it is connected. This interactive learning object includes six quiz questions.

Learners examine an animated view of the operation and programming requirements of a PLC Examine-On instruction. A brief quiz completes the activity.

Learners study the method of cascading two or more PLC timers to extend their time capacity.

Learners view an animation showing the one-shot operation of a programmable logic controller.

In this animated object, learners examine how PLC up/down-counters are used to control an automated parking lot gate.

In this animated object, learners examine the proper way to reset a counter instruction in a programmable controller.

In this interactive and animated object, learners study how to wire field devices to a PLC sourcing input module. A brief quiz completes the activity.

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

In this animated object, learners examine how to use a programmable logic controller as an alternative to hardwiring a ladder logic circuit.

Learners study the descriptions of the three words in a PLC timer: EN, DN, and TT. They then test their knowledge in a brief quiz.

In this interactive object, learners view a practical application of a PLC Timer-On function.

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 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.

In this animated object, learners study the problems that develop if the scan time of a PLC is too slow.

Learners examine the three steps of a processor scan cycle.

In this animated object, learners examine the operation and programming requirements of a PLC Examine-Off instruction. A brief quiz completes the activity.

Learners examine how a PLC Timer-Off instruction is used in the operation of an automotive paint booth.
