Created by the OPC Foundation, OPC is the interoperability standard for the secure and reliable exchange of data in the industrial automation space. Owl’s OSTS application provides a mechanism where data (real-time data, monitoring of alarms and events, historical data) can be accessed within an OT network using the OPC standard interface. An Owl data diode solution then transfers the data across the network security boundary to business users on the IT networks. This provides external users with access to plant data without jeopardizing the cybersecurity of the OT network.
The OPC Server Transfer Service (OSTS) application operates as an OPC client and retrieves “point” data from one or more OPC servers in the network. The point data is then securely transferred from the source side of the one-way data diode across to the destination side. On the destination side an OPC server makes the point data available to OPC clients operating on the IT networks. OSTS has received OPC Foundation Laboratory Certification and supports both OPC Data Access (DA) and OPC Alarms and Events (A&E) specifications.
