Overview: Additional PI-services supplementary to the FB 4 PI-services
The following section provides an overview of the PI services that can be started from the PLC. The significance
and application of the general FB 7 input variables (Unit, Addr ..., WVar ...) depend on the individual PI service
concerned.
PI service
TMFPBP
PI service:TMFPBP
Function: Empty location 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":
