PI service:TMFPBP
Function Blank position search:
(dependent on parameter assignment)
This service searches the magazine(s) named in the relevant parameters for an empty
location, which meets the specified criteria such as 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. The search area can be predefined in the following way by
setting parameters "MagazineNumber_From", "LocationNumber_From",
"MagazineNumber_To", "LocationNumber_To":
MagazinNu
mber_From
LocationNu
mber_From
MagazineN
umber_To
LocationNu
