Tech & Buying Guide
Essential SCADA Features for Modern IoT-Enabled Industrial Automation
The convergence of traditional SCADA systems with the Industrial Internet of Things (IIoT) has redefined factory automation. Choosing a robust platform requires more than just standard monitoring capabilities. In this era of Industry 4.0, your supervisory system must bridge the gap between legacy control systems and enterprise-level data integration.
Selecting Rockwell Automation Allen-Bradley PLCs for Small and Mid-Sized Applications
Rockwell Automation remains a cornerstone in global industrial automation. Their Allen-Bradley brand provides a comprehensive portfolio of control systems designed to meet diverse production requirements. Choosing the right programmable logic controller (PLC) is critical for system reliability and scalability. This guide analyzes the Micro and Compact Logix families to help you select the optimal solution for small and medium-scale projects.
Strategic Selection: Choosing the Right SCADA Software for Your PLC Project
In industrial automation, the SCADA (Supervisory Control and Data Acquisition) system acts as the bridge between raw machine data and actionable human intelligence. Selecting the incorrect software platform can lead to integration bottlenecks, scalability issues, and excessive long-term maintenance costs. As an automation consultant with 15 years of experience, I have guided many projects through the selection process. Below are the essential criteria for choosing a platform that ensures both performance and longevity.
