You have successfully configured a rack connection to the remote chassis to
communicate with the two discrete I/O modules. At this point you may also
configure the state of the outputs in the remote ControlNet chassis when the
processor is placed into the Program Mode or if communications are lost to the
remote chassis. This is optional. The default is to turn all outputs off when one
of the two conditions occur. To select other options, click on the Advanced tab
in the Connection Properties window. The following window appears:
IMPORTANT
RSNetWorx allows more than one exclusive owner rack
connection type to be configured to a 1747 adapter (e.g.
8-bit exclusive owner, 16-bit exclusive owner, and 32-bit
exclusive owner), however only one exclusive owner rack
connection can be operational at one time. It is
recommended that only one exclusive owner rack
connection type be configured to the adapter to avoid
contention between multiple connections.
IMPORTANT
If a rack connection type is changed to a smaller bit
configuration e.g. 32-bit to 16-bit, or 16-bit to 8-bit, the
unused bits for the new connection remains in their
previously programmed states for program mode or lost
communications e.g. last state, safe state, reset off.
