Table 8.7 1784-PCIC, 1784-PCICS and 1784-PKTCS Network Channel Status Indicators
If Both Channel Status It Means
Indicators Are
Off No power
1784-PCIC(S) driver not started
1784-PKTCS driver is not installed or the card is
not configured
Faulted card
Channel disabled
Steady red Faulted card
Alternating red/green Self-test
Alternating red/off One of the following:
Steady green Normal operation
Off Channel disabled
Flashing green/off Temporary network errors
Flashing red/off Media fault
No other nodes present on network
Flashing red/green Incorrect node address
Incorrect network configuration
(1)
UMAX is the highest node address on a ControlNet network that can transmit data.
Publication CNET-UM001C-EN-P - November 2005
• incorrect node configuration
• duplicate ControlNet node address
Take This Action
Apply power.
1. Start RSLinx software.
2. Verify that the appropriate driver has been configured
properly in RSLinx software.
Install the driver and/or configure the card.
1. Check operating system event log for details of fault (if
the PC's operating system supports an event log).
2. Cycle power to the PC.
3. Verify that you have firmly inserted the card into a PCI
local bus expansion slot and that the expansion slot
screw is tightened.
4. If fault persists, contact your Rockwell Automation
representative or distributor.
Program network for redundant media, if required
1. Check operating system event log for details of fault (if
the PC's operating system supports an event log).
2. Cycle power to the PC.
3. Verify that you have firmly inserted the card into a PCI

screw is tightened.
4. If fault persists, contact your Rockwell Automation
representative or distributor.
None
Check card's node address and other ControlNet configuration
parameters.
None
Use RSNetWorx software to configure the ControlNet
network for redundant media, if necessary.
1. Check media for broken cables, loose connectors,
missing terminators.
2. If condition persists, refer to the ControlNet Coax
Media Planning and Installation Manual, publication
and CNET-IN002
1. Check media for broken cables, loose connectors,
missing terminators.
2. If condition persists, refer to the ControlNet Coax
Media Planning and Installation Manual, publication
and CNET-IN002.
Add other nodes to the network.
1. Change card's node address so that it is less than or
(1)
equal to UMAX .
2. Stop and restart the card's driver in RSLinx software
(1784-PCIC and 1784-PCICS only).
Reconfigure the ControlNet network so that UMAX is greater
than or equal to the card's node address.
