How-To: Calculating Servo Motor Inertia Ratio for High-Speed Indexing

When an industrial automation engineer sizes a servo motor for a high-speed indexing application, simply matching the torque and speed requirements is a recipe for disaster. If the inertia of the driven load vastly exceeds the inertia of the motor rotor, the servo system will struggle to control the load dynamically. This mismatch results in […]

How to Export AutomationView Sequences to Siemens TIA Portal via XML

One of the most persistent bottlenecks in PLC engineering is translating a process sequence from a specification document into hardware-specific code. With AutomationView, you design your logic in a high-level, hardware-agnostic SFC/Python environment. But how do you get that logic into a Siemens S7-1500 controller? The answer lies in our native PLCopen XML export engine, […]

How-To: Designing Perspective Dashboards in Ignition SCADA for Multi-Monitor Control Rooms

When transitioning from legacy Vision modules or older SCADA systems to Inductive Automation’s Ignition Perspective, engineers often try to force pixel-perfect absolute layouts onto a responsive, web-based platform. This approach breaks down rapidly in a modern control room featuring varied monitor resolutions and aspect ratios. Building dashboards for multi-monitor setups requires a fundamental shift towards […]

The Convergence of Cybersecurity and Functional Safety in 2026 Automation Procurement

For decades, automation engineers treated functional safety and network security as two completely distinct silos. A safety PLC handled e-stops, while a firewall (often managed by IT) guarded the perimeter. In 2026, the explosive growth of connected IIoT devices and Edge AI has obliterated that boundary. You can no longer guarantee the functional safety of […]

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 […]

Deep Dive: Three-Phase Motor FLA Calculation for Precise Overload Sizing

A smoking motor on the plant floor is a rapid way to halt production and burn through maintenance budgets. While modern Variable Frequency Drives (VFDs) offer sophisticated electronic motor protection, countless induction motors are still driven by traditional across-the-line starters or soft starters. The primary defense against melting stator windings in these setups is the […]

Deep Dive: Resolving Merge Conflicts in PLC Logic using AutomationView’s Visual Diff

For decades, collaborative PLC programming was virtually impossible. If two engineers edited the same ladder logic file simultaneously, the result was a binary collision—whoever saved last overwrote the other’s work. By integrating native Git version control, AutomationView fundamentally solved the concurrency problem. However, concurrent engineering inevitably leads to merge conflicts. Resolving these conflicts in raw […]

Deep Dive: Designing Ergonomic Alarm Annunciation for High-Stress Control Rooms

When a critical failure cascades through a plant, the control room transforms into a high-stress environment. If an operator is bombarded by a wall of indistinguishable red flashing lights and a cacophony of sirens, cognitive overload occurs within seconds. HMI alarm annunciation is the critical bridge between a process fault and the operator’s corrective action. […]
