Tag Files Allow You to Access Multiple Control Engines...
Multiple STEP 7 programs can be mapped into a single tag file, with each program
providing access to a different computer and control engine. This allows SIMATIC
Computing to access data from different computers and control engines
simultaneously.
As shown in Figure 1-9, you can connect your program to control engines residing
on several different computers. You use the TagFile Configurator to insert more
than one control engine into a tag file. Refer to the
SIMATIC Computing User
Manual for detailed information about using the TagFile Configurator.
