triggered, such as Index Initiates, Program Initiates, Jog
Initiates and so on. Sources are located on the left side of
the Assignment view and reflect the status of events that
occur in the drive. These events are based on drive activity.
Figure 91 shows an example of the Assignments view.
Figure 91: Assignments View
Sources and Destinations are put into groups based on
functionality. By expanding individual groups, you will see
the individual Sources or Destinations.
For example, if you expand the Inputs source group, you
will see SP I/O, SP Inputs, EZ Motion Inputs, and I/O Plus
I/O if a module is used. You can use these Source events
to trigger certain actions (or destinations) on the right side
of the view.
To make an assignment in the SM-EZ Motion module, you
must assign a Source to a Destination. Any Source can be
tied to any Destination to create the desired system
operation.
Creating An Assignment
Various methods can be used to assign a Source (such as
SPInput.4) to a Destination (such as Index.0.Initiate).
Drag-and-Drop Method
Point to the Source, on the left, that is to be assigned to a
Destination, on the right. Press and hold the left mouse
button down, drag the Source until the mouse pointer is
positioned over the desired Destination and release the left
mouse button.
Once the mouse button is release, the assignment is
created. The view will update to show that the assignment
was created. In the Source side, the "Assigned To" column
will show which Destination was assigned to the Source. In
the Destination side, the "Set From" column will show
which Source has been assigned to it.
Destinations can also be dragged from right to left, over to
Sources.
Assign Button Method
Select both the Source and Destination that are to be
assigned to each other. Once both are selected, the Assign
button in the lower left corner of the view will become
enabled. Click Assign to complete the assignment.
The view will update to show that the assignment was
created. In the Source side, the "Assigned To" column will
show which Destination was assigned to the Source. In the
Destination side, the "Set From" column will show which
Source has been assigned to it.
Any source can be assigned to up to ten different
destinations maximum. Any destination can have as many
sources as desired assigned to it.
Deleting An Assignment
Delete Button Method
Select both the Source and Destination for the assignment
to be deleted. Once both are selected, the Delete button in
the lower left corner will become available. Click Delete will
remove the assignment.
Right-Click Method
Point to the specific assignment to be deleted and
right-click. A shortcut menu appears, click Delete.
After either of these methods, the assignment will
disappear. The "Assigned To" and "Set From" columns will
no longer have any data for the specific Source and
Destinations assignment.
Assignment Polarity
The active state of an assignment can be programmed to
be Active Off, Active On, or Custom using PowerTools Pro.
Making an assignment "Active On" means that the
Destination will become active when the Source it is
assigned to becomes active, and is inactive when the
Source is inactive. Making an assignment "Active Off"
means that the Destination will be active when the Source
it is assigned to becomes inactive, and will be inactive
when the Source is active.
The polarity of the assignment can also be changed to
Custom when required. Custom polarity allows you to
make a Destination activate and inactivate based on two
different Sources.
N
ote
Destination functions that initiate motion
(Jog.PlusInitiate, Jog.MinusInitiate, Index.#.Initiate,
Home.#.Initiate, and Gear.Activate) should not be
set to "Active Off". This could cause motion to initiate
on loss of I/O Power.
Default polarity for a new assignment is "Active On". There
are two methods that can be used to change the polarity of
an assignment.
