ISA-95 and IIoT Integration: Bridging IT and OT in Modern Manufacturing
· 9 min read
ISA-95 was created in the late 1990s to solve a simple problem: how should enterprise systems (ERP) communicate with plant floor systems (PLCs and SCADA)? Two decades later, IIoT platforms have disrupted the neat hierarchical model that ISA-95 defined. Data now flows from sensors directly to the cloud, bypassing every layer in between. The question for manufacturing engineers in 2026 isn't whether ISA-95 is still relevant — it's how to reconcile a framework built for hierarchical, on-premises architectures with the reality of cloud-native, edge-computing IIoT platforms.
