Chain magazine
The setting in MD22550: $MC_TOOL_CHANGE_MODE may only have the value 1 for these
magazine types.
Chain magazines do not as a rule have any additional buffer available for transportation
between magazine and spindle. These additional buffers can contain tools temporarily.

Circular magazine
The setting of MD22550: $MC_TOOL_CHANGE_MODE normally has the value 0.
Circular magazines do not have any additional buffer with which tools can be transported
from the magazine to the spindle. The tools on circular magazines are not physically
transported into the spindle, but are moved into a defined position through rotation of the
turret so that machining can take place with one particular tool. The tool is only transported
to the spindle or tool holder in the software. Transporting the tool to the buffer 9998/1
(spindle) serves to inform the tool management that the turret holding the requested tool has
been turned to the machining position.
The programming command T = identifier initiates the tool change. T = location can be
programmed as an alternative. If T = location, no tool need actually be stored in the location.

If the value 1 is also set for the revolver in MD22550: $MC_TOOL_CHANGE_MODE, the
statement made for the chain magazines also applies here.
