## Productivity 2000 PLC Drum Sequencer Instructions

The PLC productivity series includes a Drum and Sequencer instruction that can be very useful. The Drum instructions function similarly to an electromagnetically-operated drum sequencer. To better understand this concept, consider the mechanics of a music box. A small drum with pegs catches and flicks the chimes in a specific sequence to produce a tune. … Read more

## Productivity 2000 PLC Program Control

The program control method and instructions will allow us to specify what parts of the logic get solved and when this happens. This will control how the PLC will scan and solve your logic in your program using a synchronous PLC Scan. Understanding the PLC program scan post will explain synchronous and asynchronous program scanning. … Read more

## How to Program PLC Input Debounce On and Off

Programming an input to debounce on and off can be done using logic control systems like Programmable Logic Controllers (PLCs). This process helps to ensure the accuracy of signals sent to and from PLCs and eliminates noise interference. Using the Productivity Suite PLC Programming software, we will demonstrate the ladder logic using the simulator. We … Read more
