4.3.3 M Device/D Device Commonizing Setting

When using the multi-project function, the arbitrary number of points from the head of M device/ D device can be set as the
common device among projects. When the commonizing setting is carried out, the amount of points set by the user from the
head of device (M0/D0) will be the device (common device) that can be commonly accessed from each project. Other devices
will be the ones that are independent among the projects (independent device). The device commonizing setting can be set
from the built-in PLC (built-in edit function). (Refer to "11.3.3 Multi-Project Setting Parameter (Device Setting)")
 Example of setting procedure
Maximum project No3; M device 10240 points are commonized; remaining points are allocated to each project as
independent points.
(1) (Preparation) Confirm the maximum project points
Set "0" to each project and the common points to confirm the maximum allocable number.
(2) Setting the common points
Input the number of points "10240" to the common points among projects.
After the input of points, the total number and the remaining number will be updated.
Remaining 51200 points are distributed to each project, only by the amount of points which are used as independent
devices.
(3) Distribute the remaining points to the independent points.
After the input of the points to each project, the total number and the remaining number will be updated.
Distribute the device points to each project in only the amount
that is to be used as the independent device.
(4) Reboot the power of CNC
When the setting is carried out as the example shown above, the device range will be as the table shown below.

61440 points will be distributed to each project and the
common points.
Remaining : 51200 points
(Maximum project points (61440) – Common points (10240)
can be distributed to each project.
Input the number of points 10240, which will be common.
Points can be distributed to each project until
the remaining number becomes 0.
