Tag Files Allow You to Use Symbols for Process Data...
A tag file provides a source of symbolic information for memory locations and
control engines. Linking to a tag file allows you to use symbolic names instead of
absolute addresses when assigning tags in SIMATIC Computing (refer to
Figure 1-8).
The TagFile Configurator creates a tag file that provides a source of symbolic
information for the memory locations and control engines. The tag file can then be
used on a computer on which STEP 7 is not installed.
Refer to the SIMATIC Computing User Manual for detailed information about using
the TagFile Configurator.
