As you can see, the 1747-SCNR and 1747-ACN15 are shown as nodes 1 and 3
respectively. Under the 1747-ACN15, the 3 I/O modules in slots 1 through 3
of the 1747-ACN15 chassis are listed. In order to establish a 16-bit rack
connection to the 1747-ACN15 chassis, right click on the 1747-ACN15 and
choose ControlNet Configuration. The following window opens:
Note that addresses in the Connection Properties screen above are already filled in.
To have RSNETWORX choose the next available valid I/O or M-file
addresses for all connections, click on the Auto Address Preferences button. Next,
click on the box next to Enable Automatic Addressing on Insert so a check mark
appears in the box. Then click OK. Automatic Addressing enabled is the
default.
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.
