For a symmetric search (see parameter "SearchDirection")
•
the search domain may stretch only over a single magasine (cases 2 and 5 from the table
given above). If another search domain is specified, the service will malfunction.
•
a reference location must be specified in the parameters "MagNrRef" and "PlaceNrRef",
with respect to which the symmetric search is done.
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 before 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 with the associated
parameter "WVar1" for this PI service. See PI service MMCSEM for more information.
