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 study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.
Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.
In this animated object, learners view a race of two boats as an example of how the derivative function of a PID controller shortens the time duration of an operation.
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.
Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
Learners study animations showing the integral function of a closed-loop control system and the difference between the two types of integral controller settings, reset rate and reset time. A short quiz completes the activity.
Learners examine the formulas that are used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Continuous Cycling Tuning Method.
In this animated object, learners examine the operation and programming requirements of a PLC Examine-Off instruction. 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.
