2.12.6 FB 7: PI_SERV2 general PI services
Description of functions
A detailed description of the FB 7 is contained in the description of FB 4. The only difference
to FB 4 is the number of WVar1 and subsequent parameters. In FB 7, 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.
