Entry 6

of any Channel API exception is a code uniquely identifying the software

component of the Channel API which reported the exception.

Entry 2

(hexadecimal) codes are as follows:

“LAN system-software fault; resuming”
Internal error: The Channel API software encountered an internal use (as
opposed to user application use) of a channel number that is out-of-range.
Entry 3

contains the offending channel number.

“LAN data memory exhausted-check parms; resuming”
Internal error: An attempt to allocate a buffer failed. Entry 3 contains the
channel number. Entry 4 contains the number of bytes the Channel API was
attempting to allocate.

“LAN system-software fault; resuming”
Internal error: The Channel API detected the improper internal use of a
NULL pointer to a channel machine.

“LAN system-software fault: aborted assoc. & resuming”
Internal error: A Channel API event arrived in a channel machine state that
is not intended to handle the event.

Entry 3

contains the aborted channel number. Entry 4 contains a code

uniquely identifying the event. Valid event codes are:

1 TCP_DATA_RDY

2 TCP_ERROR

3 TCP_CONN_OK

4 TCP_FIN_RCVD

5 TCP_USER_RESET

6 TCP_CONN_IND

7 TCP_OKTOSND

e END_OF_SWEEP

f UPDATE_WAIT_EXPIRE

“Backplane communications with PLC fault; lost request”
Internal error: An attempt to write to the user-specified reference address to
be used to hold the COMMREQ Status (CRS) bits failed internally. Entry 3
contains the CRS word value to be written. Entry 4 contains the Segment
Selector of the reference addressed. Entry 5 contains the (zero-based) Offset
of the reference address.
