Explanation
The length of the Map Descriptor defined to expose driver
statistics must be at least 660.
You may safely ignore this message. Read Appendix B.1
for information
communication statistics using a Data Array.
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
< timeout.
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.
A connection request has been received for the Node
emulate named in the error message but this Node has not been
defined in the CSV file. The connection has not been
established.
This could result from a corrupted message or it may
bytes indicate an unexpected/unsupported aspect of the SNP
protocol. If the message occurs frequently, take a log and
report the error to FieldServer.
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.
This is the FieldServer slave reporting its T1 timer after a
Client has established a connection No action is required.
No action is required. A Client has attempted to re-
establish a connection that is already open.
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
declined 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.
This message is reported when the driver receives an
msg
unexpected SNP message. Record this information, take
a log and report the error to FieldServer.
