390 DH-485 Blocks
Send Type
When you select DH-485 in the Configure Control Options dialog box,
the DH-485 Value block, with Send type, it sends a value from a local
DH-485 variable (or multiple contiguous values) in the motion controller,
to a remote DH-485 element (or elements), and waits for the transfer to be
acknowledged.
Specifying the Remote Element Indirectly
Not selecting Specify Remote Addressing, causes the DH-485 remote
variable scrolling list to appear in the lower right part of the dialog box.
The scrolling list contains previously defined remote elements. By
selecting a previously defined remote element, you are specifying that
remote element indirectly.
For example, the DH-485 Value block settings in the DH-485 Value
dialog box displayed above, read the DH-485 remote element SLC_N7_3
(file element N7:3 in the SLC at node 2) into the DH-485 local variable
Parts_Count.
The remote element SLC_N7_3 was defined in the following dialog box
accessed via the Tag Explorer and the Tag Window.
See the Online Help for more information on defining variables.
