e-13 “Backplane communications with PLC fault; lost request”
The Backplane (PLC) Driver module returned bad status in response to a request.
The specific value of entry 2 is internally significant. Entry 4 provides the list
of status codes that may be returned by the Backplane Driver. These status
codes are as follows:
2 The Backplane Driver could not access the PLC.
3 Invalid binding on the message sent to the Backplane Driver.
4 The message could not be sent to its destination because the mailbox was
not open.
5 The maximum number of transfers to the destination are already taking
place.
6 The maximum number of transfers of this transfer type are already taking
place.
7 Can not obtain a Dual-Port RAM buffer.
8 Can not obtain resources (other than Dual-Port RAM).
9 Connection ID or block transfer ID is not valid.
a Timed out waiting for CPU response.
b The CPU aborted the request.
c An invalid message type was specified.
d The specified task is not registered.
e The mailbox offset specified is invalid.
f Argument “msg_rsp” may not be NULL.
10 Argument “unsol_rsp” may not be NULL.
11 Parameter pointer unexpectedly NULL.
12 More than allowable byte length in a single transfer.
13 Bad sequence number in the request.
14 Invalid command in request.
15 Actual response length not expected size.
16 Service Request Processor not available.
17 No text buffer available.

16 “LAN system-software fault; resuming”
Internal error: Event routine indication for an endpoint identifier that should
not receive such an indication. Entry 4 contains the endpoint identifier.
18 “LAN system-software fault; resuming”
An event has arrived to an SRTP Server state machine and no transition exists
for the event in the machine’s current state. Entry 4 contains an
internally-significant event code.
19 “LAN system-software fault; resuming”
Internal error: NULL transaction machine pointer detected.
1a “LAN system-software fault; resuming”
Internal error: NULL connection machine pointer detected.
