Inside CIP Safety over EtherNet/IP: A Technical Guide

Replacing hardwired relays with networked safety devices brings immense flexibility to the plant floor. However, when engineers are tasked with implementing CIP Safety over EtherNet/IP, they quickly discover that sending SIL 3 data across a standard IT infrastructure introduces complex timing and verification challenges. Rather than assuming the underlying Ethernet network is infallible, the protocol […]

Programming VFDs via Ethernet/IP in Studio 5000

Connecting a Variable Frequency Drive (VFD) via hardwired I/O is a relic of the past. Modern industrial installations demand the rich data and simplified wiring that Ethernet/IP provides. However, configuring Add-On Profiles (AOPs) and managing implicit messaging in Rockwell’s Studio 5000 introduces its own set of complexities. A single misconfigured Requested Packet Interval (RPI) can […]

7 Proven Industrial Ethernet Cable Selection Tips for Success

The Reality of Specifying an Industrial Ethernet Cable Walk onto any factory floor running heavily automated robotic cells, and you’ll quickly realize that specifying an Industrial Ethernet Cable isn’t just a matter of ordering a standard spool from a catalog. When an unshielded Cat5e line fails due to EMI from a large variable frequency drive, […]
