This extended project data volume is available after you upgrade the firmware of
the Technology CPU and of the integrated technology.
Synchronous technology processing in the user program with OB65
The technology synchronization interrupt OB65 a technology interrupt which is
called and processed synchronously to the update of technology DBs. OB65 can
be used to evaluate current and consistent data of technology DBs (see also
Technology DB updates ).
Encoder / data record changeover
S7-Technology V2.0 supports encoder and data record changeover in runtime.
You can use the encoder changeover function to determine the material position,
for example, the axes in position, in systems containing several actual value
encoders.
Use data record changeover to modify axis parameters (controller parameters, for
example) when the system is in run.
