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 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 interactive object, learners follow the steps required for the Ziegler-Nichols Continuous Cycling method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
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 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 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.
