For a symmetric search (see parameter "SearchDirection")
• the search area may stretch over only a single magazine (cases 2 and 5 from the above table). If another
search domain is specified, the service will malfunction.
• a reference location must be entered 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 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.
