Question

Quizplus · Accepted Answer

Programmable logic controllers are primarily categorized according to the number of input/output points that they have. This is because the number of I/O points indicates the capacity of the controller to handle multiple input and output signals from external devices and sensors. Other factors like current rating, power rating, and cost of I/O modules may also affect the performance and efficiency of the PLC, but they are secondary considerations when it comes to categorizing them.
