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

Learners examine the elements of a data file memory of an Allen-Bradley SLC-500 programmable controller. A quiz completes the activity.

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.

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

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

Learners examine the two methods used by programmable logic controllers to perform a counting operation using addition or counter instructions. A brief quiz completes the activity.

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

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.

In this animated object, learners examine the types of information to enter, and the sequence of steps required, to program a programmable logic controller (PLC) timer.

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

Learners examine the three steps of a processor scan cycle.

In this animated learning object, students examine the addresses of PLC elements and how they pertain to I/O connections and internal memory files.

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.

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.

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

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

Learners examine the animated Timer-On Delay instruction and the Timer-Off Delay instruction of a PLC timer. A brief quiz completes the activity.

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

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