Overview of additional PI services
The following section provides an overview of the PI services that can be started from the
PLC. The meaning and application of the general FB 7 input variables (Unit, Addr..., WVar...)
depends on the individual PI service concerned.
PI service Function Available in

Empty location search
TMFPBP
Function:
(dependent on parameter assignment)
This service searches the magazine(s) named in the relevant parameters for an empty
location, which meets the specified criteria (tool size and location type). The result of the
empty location search can be fetched from variables magCMCmdPar1 (magazine number)
and magCMCmdPar2 (location number) in block TMC when the service has functioned
correctly. As the PI service stores a result in variables magCMCmdPar1 and
magCMCmdPar2, the service must be protected by the semaphore mechanism (PI service
MMCSEM) with the function number for _N_TMFDPL in cases where several control units or
PLCs are operating on one NC.
