   An OPC Server for one hardware device provides the same methods for an OPC client to access its data as any other OPC Server for any hardware device. The aim was to reduce the amount of duplicated effort required from hardware manufacturers and their software partners, and from the supervisory control and data acquisition (SCADA) and other ...

6. Inductive Automation - Wikipedia

   en.wikipedia.org/wiki/Inductive_automation

   Inductive Automation promotes cross-platform operating system choices for SCADA, [15] citing that Windows has been a requirement due to the reliance of DCOM within OPC-DA, but organizations desire Linux for "security", "stability" and "reliability". [16] Inductive Automation introduced Linux support in Ignition with the OPC-UA module in January ...

7. OPC Historical Data Access - Wikipedia

   en.wikipedia.org/wiki/OPC_Historical_Data_Access

   OPC technology is based on client / server architecture. Therefore, an OPC client, such as a trending application or spreadsheet, can retrieve data from an OPC compliant data source, such as a historian, using OPC HDA. Similar to the OPC Data Access specification, OPC Historical Data Access also uses Microsoft's DCOM to transport data. DCOM ...
