A new extended status
code available: 16#812.
The 1756-CNB and 1756-CNBR modules now report error code
16#812 whenever its node address does not match the expected
address.

A single-channel
1756-CNB module at
the lowest node causes
a network disruption.
Using a single-channel 1756-CNB module as the lowest node on a
ControlNet network that has media redundancy configured for
channels A and B or as a B only network may prevent normal
network operation.
Symptoms include the following:
• Loss of all scheduled connections for the network
• New devices are prevented from joining the network
• Module fault. Display reads:
ASSERT: smacdrvr.c line 3440
Lgx00076950
A fault occurred due to
an unterminated
ControlNet cable.
Leaving the ControlNet network unterminated for long periods of
time may cause the 1756-CNB or 1756-CNBR modules to fault. The
module display reads: ASSERT: smacisr.c.
Lgx00070692
11.004 A power cycle caused a
persistent fault,
16#0304.
A 1756-CNB or 1756-CNBR module that is also the current Active
Keeper may fail any connections with an error code 16#304 (No
Scheduled Configuration) if lower nodes are power cycled just after
a major network disruption.
Lgx00076167
The ControlNet channel
media redundancy state
not configured correctly.
A 1756-CNB or 1756-CNBR module that is the current Active Keeper
may not apply the channel media redundancy state correctly after a
new RSNetWorx software project has been downloaded.

11.002 1756-CNB and
1756-CNBR modules
stop communicating.
All 1756-CNB and 1756-CNBR modules with firmware revisions prior
to 11.002 will stop communicating after 70.96 days of powered
operation. If this occurs, the OK status indicator will be solid red and
the four character display on the front of the module will either
freeze or scroll the message: ASSERT main.c line 1231.
This anomaly can be avoided by removing and reinserting the
ControlNet module, or cycling power to the chassis within the 71
days. Because the module will halt in another 70.96 days, you must
perform a mandatory firmware upgrade to revision 11.002.
1756-CNBR module may
revert to using channel
A only.
If the 1756-CNBR module is the only Active Keeper on the network
while cycling power or there is a disruption, the module may revert
to using channel A only
