Industrial Applications

1. High-speed packaging line controller

The 0.016 μs instruction time and 400K-step program capacity suit synchronized packaging machines with many interlocked axes, sensors, and recipe logic.

Problem Solved

Maintains deterministic scan performance in dense, high-I/O packaging automation without exhausting program memory.

2. Distributed machine cell networking

Built-in EtherNet/IP and 128 CIP Class 3 connections make it suitable for cells that must exchange data with drives, HMIs, remote I/O, and SCADA systems.

Problem Solved

Eliminates the need for a separate network gateway while supporting large cyclic and explicit-message traffic.
