Appendix A 1756 ControlNet Status Indicators
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)
The 1756-CNB/E module is disqualified without a partner.
Check corresponding slot of primary chassis for type and revision of module.
PwDS
(2)
The 1756-CNB/E module is primary with a disqualified secondary partner.
Check the type and revision of the module.
PwQg (2) The 1756-CNB/E module is primary with a qualifying secondary partner.
PwQS
(2)
The 1756-CNB/E module is primary with a qualified secondary partner.
PwNS
(2)
The 1756-CNB/E module is primary with no secondary partner.
Check the corresponding slot of the secondary chassis for the correct module.
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.
