Rockwell Automation 1738-ADNX ArmorPoint I/O DeviceNet Adapters - Manual (Page 81)

Publication 1738-UM001A-EN-P - February 2005
Quick Start For the 1738-ADNX B-7
17. Remove the 1738-ADNX from the scanlist for now by clicking
the double arrows.
18. Click OK. When prompted if you want to download changes to
the device, click Yes.
At this point you have a choice:
• You could start another instance of RSNetWorx for DeviceNet
and configure the Subnet. You would then see the
1738-ADNX at node 0 on the Subnet and add the ArmorPoint
I/O to its scanlist. You would then map the data to the exact
location you want it. For example, if ladder logic was already
written, you could map it to an address.
• If you have not written your ladder logic yet and you are not
particular about the mapping, you could use the auto start
feature of the 1738-ADNX to map all the devices
automatically from the primary network. After the mapping is
complete, look at the Subnet to verify that everything worked
as expected.
19. Verify that the subnetwork taps are electronically isolated and
have their own terminating resistors at each end.
IMPORTANT
The Subnet must always be properly terminated. In
this example, there is a terminating resistor at each
end of the Subnet trunk.
Click the
double left
arrow to
remove the
1738-ADNX
from the
Scanlist. Then
verify that the
Scanlist is
empty. You will
return here
later after
RSNetWorx for
DeviceNet
knows more
about the
devices on the
Subnet.
