4-6 Application Examples
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 Insert
Connection. 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. Auto 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.
