OPC Security: Controlling Access to Critical System Data
Now that OPC has successfully solved connecting applications to data sources, the next step is to explore how OPC can control access to critical data. Critical system data linked via OPC requires restrictions on who has read and/or write access. On an application level, OPC utilizes Windows security to control access to data. The OPC Security specification enables a more granular approach to data access control. Using the OPC Security specification it is possible to control exactly who has what access to critical system data.

Eliminating OPC Setup Headaches
From the shop floor to the top floor, OPC is the preferred communication standard for sharing process control data at all levels of the enterprise. But as OPC pours into mainstream acceptance, integrators are finding configurations where OPC can be a hindrance to the panacea of plug-and-play application interconnectivity. The most common situation occurs when applications on different Windows domains must communicate with each other. Still, other designs call for the use of low-bandwidth or unreliable networks. Rapidly detecting what is hampering OPC connectivity and knowing the solution is the key to successfully integrating OPC.
