Body

Currently only a limited number of data types are supported for the PLC4X S7 adapter. This should be extended to support all data types that PLC4X offers.

Mentoring

As this issue is marked as good first issue: one of @dominikriemer, @tenthe, or @bossenti are happy to provide help for getting started, just tag (one of) them if you want to start working on this issue and need some help. This issue is ideal for people that are interested in getting started with StreamPipes and ideally (but necessarily) have some experience with PLC4X.
