Connecting To A Specific Control Engine Over Dcom - Siemens SIMATIC WinAC Slot 412 Manual

Distributed Component Object Model (DCOM)
A.2 Connecting to a Specific Control Engine Using DCOM
As shown in Figure A-3, you can use the SIMATIC data control to connect your
program to a control engine residing on a different computer.
Note
If you set up SIMATIC Data Control for a direct connection to a control engine, you
cannot assign a tag file. In other words, you cannot use symbol names for the tags
in the control engine.
To use symbol names, select the option for connecting via a tag source and
browse to a tag file that contains symbols for only one control engine. Use the
TagFile Configurator to create tag files and connect to control engines using
DCOM. See the SIMATIC Computing User Manual for information about using
STEP 7 and the TagFile Configurator.
