Difference to X4

Difference between aop adapter and X4 interface

SST no longer DLLs, but EXE (AOP component)
WinGuard continues to take over start and end of the module, however, SST connects automatically and therefore can also run remotely
Unified XML definition of Object model (previously data types) and Mapping (previously Handling) instead of individual INIs
SST only needs to be installed at stations where it actually “runs”.
