Appendix C. Reference
Appendix C.1. Error Messages
Message Explanation
SNP:#1 FYI. The MapDesc called
<%s> is too short. The length of the Map Descriptor defined to expose driver statistics must
be at least 660.
6
SNP:#2 FYI. You could have used a
MapDesc called <%s> to expose
diagnostic info.
You may safely ignore this message. Read 0 for information on how to
expose the driver’s communication statistics using a Data Array.
SNP:#3 FYI. SNP device requires
inter msg timer < timeout.
Nid=<%s>.
The driver is required to use the larger of its own or the PLC’s T1 (Inter
message) timer. This message is produced when the PLC returns a T1 timer
that is larger than the driver’s timeout. Using this timer will mean that
every message will timeout. Increase the timeout for the Node, connection
or Map Descriptor as appropriate.
6
SNP:#4 Error. Cant emulate
Node=<%s>
A connection request has been received for the Node named in the error
message but this Node has not been defined in the CSV file. The
connection has not been established.
6
SNP:#5 Err. Total Bytes
expected/rcvd=%d/%d
This could result from a corrupted message or it may indicate an
unexpected/unsupported aspect of the SNP protocol. If the message
occurs frequently, take a log and report the error to FieldServer.
SNP:#6 FYI. T1 timer set to <%ld>
mSec.
This message requires no action. It reports the T1 timer value selected by
the slave in milliseconds. If the value is large then this will slow the
communications rate and you may wish to reconfigure the slave.
SNP:#7 FYI. T1 timer reset to <%ld>
mSec. This is the FieldServer slave reporting its T1 timer after a Client has
established a connection No action is required.
SNP:8 FYI. Subsequent connect
response ignored. NName=<%s> No action is required. A Client has attempted to re-establish a connection
that is already open.
SNP:9 Err. Device declined request.
Mjr=%x(h)
Min=%x(h)
Possible Offending Poll =<%s>
addr=%d length=%d
This message uses two lines of the error log. It is printed when a slave
declines a request. The major and minor faults are reported. These
numbers are printed in hexadecimal. See Appendix C.3 for further details.
The message reports the Map Descriptor which generated the rejected
poll, the data type, the address and the number of elements being
requested. Often this message will be the result of a poll that requests
data past the end of a PLC data table or when the length is based on a BIT
count but the poll actually requests Bytes.
6
SNP:10 Err. Wrong msg type=%d(h)
mbox=%x(h)
This message is reported when the driver receives an unexpected SNP
message. Record this information, take a log and report the error to
FieldServer.
