SNAP I/O for AB, Part 4: PID Loop Control

Summary

Summary

SNAP I/O is more than just an I/O bus-coupler with Allen-Bradley controllers. It independently runs multiple PID control loops, each with a separate scan time, without slowing down the main controller.

Part 4 demonstrates how to:

  • Configure a PID loop
  • Write a setpoint from RSLogix
  • Graphically tune the PID
