Wireless PLC Upgrades & IIoT Integration: The Future of Automation

By DANIEL GOMES June 15, 2025

🔗 The Future of Industrial Automation: Embracing Wireless PLC Upgrades and IIoT Integration

Industrial automation is rapidly evolving, with manufacturers worldwide replacing outdated systems with smarter, wireless, and IIoT-ready solutions. This isn’t just a trend—it’s the new standard. At PLCpartssolution.com, we’ve seen growing interest in wireless PLC upgrades and cloud-connected modules, especially from trusted names like Allen-Bradley, Siemens, Schneider Electric, and Omron.

🔎 Author Note: With over 20 years of industry experience, our team at PLCpartssolution.com combines deep technical knowledge with real-world automation expertise, helping engineers, integrators, and OEMs find the right parts—fast. All content here is written by automation specialists and reviewed by certified industrial technicians.

📡 Why Wireless PLC Retrofits Are on the Rise

Legacy PLCs are limited by fixed wiring and rigid infrastructure. With the growth of wireless communication technologies, modern factories can:

  • Reduce installation and maintenance costs

  • Enable remote access and cloud monitoring

  • Scale automation networks without major rewiring

Products like the Allen-Bradley 1769-ENBT and Siemens S7-1200 Ethernet modules are now commonly upgraded with wireless gateways, creating smart, flexible control systems.

🌐 IIoT-Ready PLCs: Smarter, Safer, and More Scalable

Industrial Internet of Things (IIoT) integration is one of the most powerful upgrades manufacturers are adopting. PLCs with built-in IIoT features offer:

  • 🌡️ Real-time sensor data

  • 🧠 Predictive maintenance using AI algorithms

  • ☁️ Cloud dashboards for cross-site control

  • 🔐 Stronger cybersecurity and encrypted communication

Explore options like the Siemens S7-1500 series or Modicon M580 by Schneider Electric, which support OPC-UA, MQTT, and other IIoT protocols.

🏭 Customer Example: Smart Retrofitting with Allen-Bradley

A major OEM recently upgraded from an Allen-Bradley SLC 5/04 system to a CompactLogix architecture, adding wireless Ethernet/IP capability using 1769-series modules. This allowed them to:

  • Minimize downtime during migration

  • Add remote HMI access via Wi-Fi

  • Improve data reporting across 12 lines

Thanks to in-stock availability and same-day shipping from PLCpartssolution.com, the transition was completed in under a week.
