Category: OPC Classic

OPC Classic refers to the original OPC standards used for industrial communication, including OPC Data Access (DA), OPC Alarms & Events (AE), and OPC Historical Data Access (HDA). These technologies enabled standardized data exchange between industrial systems, SCADA platforms, and enterprise applications in legacy environments.

Although newer standards such as OPC Unified Architecture (OPC UA) provide enhanced security and platform independence, OPC Classic remains widely deployed in existing industrial infrastructures.

This category includes articles and technical resources covering OPC Classic architecture, integration strategies, system maintenance, and migration approaches toward modern OPC UA-based solutions
