View the Connection
Status screen in
RSNetWorx for
ControlNet software
to see why the
connections are not
established. Check to see if the
1747-SCNR and the
remote devices are
correctly connected to
the ControlNet network.
Module bandwidth is
exceeded. Reduce the number of
scheduled connections
by:
- using a discrete rack
connection instead of
multiple discrete module
connections
- combining multiple I/O
racks into a single I/O
rack
- combining multiple
peer-to-peer messages
into one message.
Increase your Network
Update Time and/or
increase the Requested
Packet Intervals for
scheduled data transfers.
Increase your SLC 500
ladder program scan by
adding more logic.
EDIT N/A The scanlist in the
1747-SCNR module is
being modified. Edits have been
enabled with
RSNetWorx for
ControlNet software.
Note that previously
configured
connections will be
reestablished if lost.
Newly configured or
changed connections
will not be
established until edits

for ControlNet software
and then accept edits.
