Description of Functions
A detailed description of the FB 7 is contained in the description of FB 4.

WVar1 to WVar16 are defined in VAR_INPUT (FB4 has WVar1 to WVar10). All other
parameters are identical to FB 4.
This PI server can be used for all PI services previously implemented with FB 4. In addition,
the PI services listed below can only be handled with FB 7.
