1.7 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).
