Asynchronous magazine with changer arm.

Asynchronous magazines have the magazine far fromto the spindle and the tool is changen
using a tool changer arm. Most of the movements may be carried out while machining the
part, thus minimizing machining time.
The communication between the manager and the PLC takes place in two stages; the first
one when executing the T function and the second one when executing the M06 function.
Execution of the T function.
1 When the CNC executes the T function, it lets the tool manager know about it.
2 The tool manager sends a command to the PLC to select the next tool in the magazine.
3 The CNC continues with the execution of the program without waiting for the tool
manager to complete the operation.
Execution of the M06 function.
1 When the CNC executes the M06 function, it calls the associated subroutine. The M06
function must also be programmed inside that subroutine so the CNC "tells" the tool
manager to start making the tool change.
2 The tool manager sends a command to the PLC to make the change.
3 The CNC waits for the tool manager to complete the operation before continuing with
the execution of the program.
The management of the tool change should be included in the subroutine associated with
the M06 and leave the control of the external devices up to the PLC. Use the auxiliary
functions to govern the various devices (magazine rotation, magazine movement, tool
changer arm, etc.) from the M06 subroutine.
If the tool change implies leaving a tool in the magazine, once executed the change and with
the tool in the arm, it is possible to activate the TCHANGEOK mark for the CNC to continue
executing the program while the tool is being left in the magazine.
