For a symmetrical search (see parameter "SearchDirection"), the search domain must only
include one magazine (cases 2 and 5 in the table above). If another search domain is
specified, the service will malfunction. A reference location must be specified in the
parameters MagNrRef and PlaceNrRef for a symmetrical search (see parameter
"SearchDirection"). The reference location is specified in the parameters MagNrRef and
PlaceNrRef. The reference location is a buffer location (a location from the magazine buffer,
i.e., change position, gripper, etc.) or a load point (a location from the internal loading
magazine). The search is executed symmetrically with reference to the magazine location in
front of the specified reference location. A multiple assignment to the magazine being
searched must be configured in the TPM block for the reference location. If this is not the
case, a malfunction occurs. If the magazine location in front of the reference location is
outside the search domain, the service responds as if it has not found a matching location.
Note
Before and after this PI service, the MMCSEM PI service must be called up with associated
WVar1 parameters for this PI service. See PI service MMCSEM for more information.
