Appendix A 1756 ControlNet Status Indicators
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.
Steady green OK Normal operation is occurring. At least one connection has been made to or through
the module.
INIT The module is initializing.
BW >MAX The module is receiving too much network traffic and connections are timing out.
The network bandwidth has been exceeded.
No action is required because this is a temporary condition.
If this happens frequently, add another module and split the traffic between them.
CMPT
(2)
The secondary 1756-CNB/E module is compatible with its partner.
DSNP
(2)

Qfng
(2)
The secondary 1756-CNB/E module is qualifying.
QS
(2)
The secondary 1756-CNB/E module is qualified.
SW ERR The node address switch changed after the module was started.
We recommend that you either return the switches to their original settings or
replace the module, since this condition could indicate a latent hardware anomaly.
Flashing green CNFG ERR The ControlNet network was configured incorrectly.
Recheck the ControlNet network configuration.
NET ERR A network cabling error exists, or no other active nodes exist on the network.
Recheck your network cabling and make sure another node on the network is active
(online).
OK Normal operation is occurring. No connections have been made to or through the
module.
