From Drum Sequencers to PLC Power: How Productivity PLCs Simplify Industrial Sequencing

To learn more: https://www.AutomationDirect.com/productivity?utm_source=6NraHu4MnOI&utm_medium=VideoTeamDescription - (VID-PRO-0009) Industrial processes often rely on repeating steps, and before electronics, these sequences were controlled mechanically with drum sequencers or cam timers. They were rugged and reliable—but hard to change. Modern PLCs replaced mechanical sequencing with software, but sometimes simple sequences require more ladder logic than expected. AutomationDirect’s Productivity PLCs solve this with two powerful tools: Drum (DRM) and Sequence (SEQ) instructions. DRM works like a virtual cam drum, stepping through predefined output patterns based on time or events—perfect for linear, time‑driven applications like wash cycles or indexing conveyors. SEQ acts like a compact state machine, letting you define steps and transitions cleanly and logically, supporting up to 200 steps and 16 outputs per step. Together, these instructions make sequencing easier, more flexible, and far more maintainable.
