Load function
Prepares the specified real magazine for the specified channel for loading, i.e. traverses the magazine to the
selected location for loading at the specified loading point/station (location_number_from,
magazine_number_from) and inserts the tool.
When location_number_to = -1, an empty location for the tool specified by a T number is first sought in the
specified magazine and the magazine then traversed. After execution of the PI, the number of the location found
is listed in the TM area in component magCMCmdPar2 for the real magazine of the channel.
With location_number_to = -2 and a valid magazine number, loading takes place into the currently queued
magazine position of the specified magazine. After execution of the PI, the number of the location for tool loading
is listed in the TM area in component magCMCmdPar2 for the real magazine of the channel.
Unload function
The tool specified by the tool number is unloaded at the specified loading point/station (location_number_to,
magazine_number_to), i.e. the magazine is traversed to the position for unloading and the tool is then removed.
The magazine location for the tool is marked as being free in the TP block. The tool can be specified either using
a T number or by means of the location and magazine numbers. An unused specification has the value -1.
Note
