FB 7: PI_SERV2 PI-services

Function
A detailed description of the FB 7 is contained in the description of FB 4.
The FB is multi-instance-capable. The call is permitted only in cyclic program OB1. An assignment for all
parameters with Req = 0 is also permitted in OB 100.
The only difference to FB 4 is the number of WVar1 and subsequent parameters. These are defined in FB 7 from
WVar1 to WVar16 (FB 4 in the VAR_INPUT from WVar1 to WVar10). All the other parameters are identical to FB
4.
This PI server can be used for all PI services that have been implemented with FB 4. In addition, the PI services
listed below can only be executed with FB 7.
