Features
Automation technology is no longer imaginable without OPC communication since this technology enables simple data exchange between automation hardware on the one side and applications on the other – via one standardized interface.
However, OPC has one critical disadvantage: It is currently based on DCOM – a technology defined by Microsoft. This means that it is not interoperable (i.e., is only available to Windows users). Applications written for non Windows computers cannot use the OPC server to access process data at the automation level (e.g., controllers). Furthermore, the DCOM configuration is anything but simple and can turn out to be very complicated. Timeouts cannot be configured with DCOM and communication across Firewalls is also impossible.
DCOM is frequently disabled for security reasons and OPC clients on Windows computers then have no other way of accessing the OPC servers in the network.
