Technological function

Note When migrating the technological functions of S7-300/S7-400 to S7-1500, in
most cases it will not be possible to migrate the components one-to-one, instead
a solution-based approach is used, i.e. hardware and software reproduce the
function together.
In the overviews below one possible solution is shown.
4.6.1

Function modules

For the S7-300/S7-400 the acquisition and the processing of process data as well
as the output of the results is summarized in one module. In comparison, for the
S7-1500 the tasks/functions are distributed to several devices in order to enable a
flexible approach. For example, for cam and positioning tasks the same module
can be used or an acquired position value is used for different functions.

listed separately in the following tables and a suitable solution is suggested,
depending on the individual case. Optimizations regarding price, function or
space are sometimes not possible, but due to the multitude of combination
options, not all variants can be listed. In the comment column, it may be referred
to features that go beyond the previous performance of FMs.
