2-24 What is the 1734-ADN(X) Adapter?
A user program can monitor the Device Failure Bit in the I/O
message(s) received from the adapter. When it has determined the bit
set, you can read the Faulted Node Table and Node Status Table, using
the Explicit Message Program Control Feature of the scanner device,
to determine the module experiencing problems and the nature of
those problems.
Chapter Summary and
What’s Next
In this chapter you learned about the 1734-ADN(X) DeviceNet
adapter. Move to Chapter 3 to learn about using Auto Start Mode.
78 No Such Device Slave device in scan list table does
not exist.
Add the device to the network, or
delete scan list entry for that device.
79 Transmit Failure Adapter has failed to transmit
a message.
Make sure that other modules exist on
the backplane.
80 In Idle Mode Adapter is in IDLE mode. No action necessary.
If you want the adapter to run, put it in
RUN mode.
82 Fragmentation Error Error detected in sequence of
fragmented I/O messages
from device.
Check scan list table entry for slave
device to make sure that input and
output data lengths are correct.
Check slave device configuration.
83 Slave Init Error Slave device is returning error
responses when scanner attempts to
communicate with it.
Check accuracy of scan list table entry.
Check slave device configuration. Slave
device might be in another master’s
scan list.
Reboot slave device.
84 Not Yet Initialized Adapter is initializing the
DeviceNet channel.
No action.
85 Rcv Buffer Overflow Data size is larger than 255 bytes. Configure the device for a smaller data
size.
86 Device Went Idle Device is producing zero length data
(idle state) while channel is in
Run Mode.
Check device configuration and slave
node status.
89 ADR Failed Failure occurred when downloading
ADR data to the I/O module.
Reconfigure the ADR download data for
the I/O module.
91 Port Bus Off Bus-off condition detected on
communications port.
Scanner is detecting communications
errors.
Check DeviceNet connections and
physical media integrity.
Check system for failed slave devices or
other possible sources of network
interference.
92 Port Power Off No network power detected on
communications port.
Provide network power.
Make sure that scanner drop cable is
providing network power to adapter
communications port.
