PI service: TMFPBP
Function: Search for empty location
(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. The search area can be predefined in the following way by
setting parameters "MagazineNumber_From", "LocationNumber_From",
"MagazineNumber_To", "LocationNumber_To":
