| Green (continuous)
|
The channel and CHARM status is good and the
CHARM is configured.
|
| Green (flashing twice per second)
|
The CHARM is not configured. If DeltaV
Diagnostics displays BAD status for this CHARM, a configuration error such as a
configuration mismatch, has occurred. If DeltaV Diagnostics displays GOOD
status for the CHARM, the CHARM has not been configured. In this case,
configure the CHARM in DeltaV Explorer.
|
| Green (flashing ten times per second)
|
A user has issued an identify CHARM command
from the DeltaV Diagnostics application. This is not a fault and no action is
required.
|
| Red (continuous)
|
No communications on the bus or no address.
- If this pattern is
seen on an individual CHARM, replace the CHARM.
- If this pattern is
seen on a group of 12 CHARMs, ensure that the correct address plug is
installed.
- If this pattern is
seen on all CHARMs, ensure that the CHARM I/O card is functioning correctly.
Additionally, if this pattern is seen on all CHARMs, the CIOC
could be in simulate mode. If the CIOC is in simulate mode, no corrective
action is required.
|
| Red (flashing twice per second)
|
Channel fault. Check wiring and associated
field device. If wiring and device are correct, replace the CHARM.
|
| Red (flashing ten times per second)
|
Duplicate address. Check all CHARMs
baseplates for a duplicate address plug.
|
| Green then red flashing four times per second
|
A CHARM fault (such as a bad address or a
faulty CHARM bus) exists that does not affect the channel status.
- If this pattern is
seen on an individual CHARM, replace the CHARM.
- If this pattern is
seen on a group of 12 CHARMs, ensure that the correct address plug is
installed.
- If this pattern is
seen on all CHARMs, ensure that the CHARM I/O card is functioning correctly.
|
| Green and red alternating two times per
second
|
The CHARM is being upgraded or is in upgrade
mode.
|
| Green then red flashing briefly once every
1.5 seconds (for output CHARMs only)
|
The CIOC has placed the CHARM in a fault
state.
|
| No colors
|
The CHARM is unpowered or not functioning.
- If all CHARMs'
LEDs have no color, check the power connections.
- If the LEDs on all
the CHARMs on a baseplate have no color, check the connection to the baseplate.
- If the LED on one
CHARM has no color, replace the CHARM.
|
| Yellow
|
This is the power indication:
- Yellow (On
continuous)-Power is available.
- Off-Power is
unavailable.
