CAN Network Errors
There are 4 types of CAN network errors:
Bit and Stuff errors
−
These refer to failures to detect a transition from the
recessive to dominant bit or vice versa, within 5 bits.
Form errors
−
These are errors in the format of a message.
Other errors
−
These are errors that do not fall into the bit, stuff, or form
error categories.
A common error is the “Ack slot OEA.” This indicates that the iControl
console is the only device on the bus. It is typical to see this error when the
fan is off and the iControl console is powered up. It is also seen if the host
fails to transmit a message, but is generally accompanied by other CAN
errors.
Transmit errors indicate a failure of the host (the iControl console) to send
data correctly.
Receive errors indicate failures on the CAN bus outside the iControl
hardware. They can include failures due to a defective iControl CAN
interface.
To enable
CAN Alarms
, touch the checkbox below the
Close
button. By
default, CAN alarms are written to the
CANstatus.log
but do not appear on
the Alarm screen. Enabling the alarms will cause them to appear on the
Alarm screen. The CAN alarm and CAN status log file lists all the CAN
messages that would normally be in the Alarm log. Up to 5 days of logs are
maintained.
