9.4.8 PI service: TMMVTL
Function
With program instance service TMMVTL, it is possible to initiate a job to relocate a tool from
the PLC. After an error-free "PI Start," the tool management performs an empty location search
in the target magazine for the tool on the defined source location. Subsequently the PLC
receives a job for relocating the tool (user interface DB41xx.DBB0).

Parameter
Result
The tool can be specified either via a T number or by means of the location and magazine
numbers. The value -1 is entered at unused specification points.
With the parameter, target location number =-1, a search is made in the complete magazine
for an empty location for the tool according to the search strategy that has been selected. If a
target location is specified, then a check is made as to whether the location with the specified
target location number is free and suitable for the particular tool.
For a target magazine number = -1, a search is made in a buffer for the tool corresponding to
the assignment obtained from $TC_MDP2.
Examples:
● When using buffers to return the tool (for example tool boy and/or shifter), an explicit empty
location search in the magazine may be needed during the asynchronous return transport.
In this case the PLC does not have to note the original location, the PI service searches
for a suitable location.
● A tool is to be moved from a background magazine to the front magazine.
