By Application

Application Typical PLC Key Requirement>
Discrete Manufacturing Micro, Compact Speed, I/O count
Process Control Modular, PAC Analog, PID
Building Automation Compact Communication
Energy Management Modular Reliability
Motion Control PAC High-speed
Pro-Tip: Choose PLC based on application—not features. Process needs analog, manufacturing needs speed.

Match PLC to application: manufacturing = compact, process = modular, motion = PAC.
