SIMATIC Computing Creates Access to Process Data
In Figure 1-7, you can see how you can use the SIMATIC Computing software to
access the CPU 41x-2 PCI for monitoring and modifying process data.
SIMATIC Computing provides several methods for accessing the process data:
You can use standard ActiveX controls (OCX) to access the process data.
You can use DCOM (Microsoft’s Distributed Component Object Model) to
integrate distributed applications across a network. A distributed application
consists of several processes or different computers that cooperate to jointly
solve a task (refer to section 1.10).
You can use an OPC (OLE for Process Control) server which other OPC clients
use to access the data in the controlled device (refer to section 1.11).
