1756-CNBR/E ControlNet
Communication Modules
This section provides the following information about status indicators:
• To understand the OK status indicator and display messages, see Tab l e 4
.
• For information about viewing the network channel status indicators
together, see Table 5 on page 46
.
• For information about viewing the network channel status indicators
individually, see Table 6 o n p a g e 46

OK Status Indicator and Display
Table 4 - OK Status Indicator and Display
Status Display Description
Off None The module is not communicating due to a power supply fault or internal fault.
Do any of the following:
• Check the power supply.
• Check the cable connectors.
• Make sure the module is firmly seated in the chassis.
• If the status indicator remains off, replace the module.
Steady red Msg scrolls
(1)
The module’s network address is set to 00, an invalid ControlNet address, or 99, an invalid ControlNet address if you are
using enhanced redundancy control. See the footnote at the end of the table.
Remove the module from the chassis, and set the network address to a valid value. For more information,
see Install a 1756 ControlNet Communication Module
on page 9.
BPA# ERR The module has detected a different slot address from that latched in when the module was started. Excessive noise on the
backplane causes this error.
Replace the chassis or module.
BPRX ERR Too many CRC errors are being generated by the multicast backplane receiver, so the backplane multicast receivers have
been shut off.
Replace the module.
BPIC ERR Hardware within the module has faulted.
Replace the module.
CNIC ERR
DUPL NODE For enhanced redundancy systems, this may be a temporary condition during chassis switchover. Otherwise, the module’s
network address is the same as another module’s on the link.
For enhanced redundancy systems only, wait 10 seconds. If the condition persists, remove the module from the chassis,
and set the switches to a unique address. For more information,
see Install a 1756 ControlNet Communication Module
on page 9.
RACK ERR The module cannot read the backplane EEPROM, or the rack/slot address is incorrect.
Replace the chassis.
STOP The 1756-CNB/E module was commanded to stop functioning by the redundancy module. This occurs when a non-
redundancy-compliant 1756-CNB/E module is placed into a redundant secondary chassis.
Remove the nonredundancy-compliant 1756-CNB/E module from the redundant secondary chassis and replace it with a
redundant 1756-CNBR/E module.
WAIT RM

or
WAIT SRM
(2)
The 1756-CNB/E module is waiting for the redundancy module to be started.
Flashing red BOOT The module has invalid firmware.
Update the module’s firmware with ControlFLASH software.
ROM UPDT A firmware update is in progress.
SNGL KPR! The module has detected that it has been connected to a ControlNet single-keeper network, version 1.0 or 1.25.
Update the firmware of module at node address 01 and reschedule the network.
