Message Explanation
SNP:11 Err. Max Tbuf Len.
FieldServer cant go bigger than %d
Bytes
Possible Offending Poll =<%s>
addr=%d length=%d
The length of some messages is variable and is dependent on settings or
the particular implementation of the SNP. Normally this driver adjusts to
use the largest size required by a Client or slave response but this message
indicates that the driver’s maximum had been reached. The data has been
discarded so it is important that the situation be remedied. The data type,
address and the number of elements being requested are reported.
Two possible solutions exist.
Change the Client’s communications configuration and reduce the size of
the text buffer length to 4096 Bytes.
Create two Map Descriptors that each read half the data.
SNP:12 FYI. Max Tbuf Len.
FieldServer != Device. Changed
FieldServer to %d Bytes
This message requires no response. It indicates that the slave requires a
longer text buffer than the driver’s default. The driver has adjusted its
buffer to the new length indicated.
SNP:13 Err. Wrong msg type=%d(h)
mbox=%x(h)
The driver has received an unexpected reply in response to a poll. Make a
log, record the values reported in this message and contact FieldServer for
support.
SNP:#14 Error. Attach Response.
Unexpected !
The driver has been polled by a Client and it has received an unexpected
message. If the error occurs repeatedly then make a log, record the values
reported in this message and contact FieldServer for support. There are a
few variations of this message but they all indicate the same problem.
SNP:#15 FYI. Node Station - forcing
to 0 The Node_ID has not been defined for a SNP Node. Read the notes in 0
and in sections 5.2 and 6.2.
7
SNP:#16 Err. Addresses start at 1.
MapDesc=<%s>
GE devices number the elements of data tables starting at element 1.
7
SNP:#17 Err. MapDesc=<%s> has
bad data type.
Refer to section 5.3.2 for a list of valid data types.
7
SNP:#18 Err. MapDesc=<%s> has
bad data type.
SNP:#19 Err. Mapdesc=<%s> has
invalid length.
A Map Descriptor must have a length. The minimum length is “1”.
7
SNP:#20 Err. do diagnostic x If you see this error, report it to FieldServer tech support. The message is
produced when a QA diagnostic is produced and should only ever be seen
during testing by FieldServer Inc.
SNP:#21 Err. do diagnostic x
SNP:#22 Err. do diagnostic x
SNP:#23 Err. Illegal Node_ID [%d] -
Set to 1
Legal Node_ID’s are 0-65535.
7
GE_SNP:#24 FYI. Parse Error:
Attach: CPU ID is not Null
terminated.
The CPU Id is a max 10 characters including the terminating Null character.
The driver has found one that isn’t correctly formatted. This error may be
ignored. It will not affect operation of the driver. It does mean the driver
cannot store the name of the connected device in the stats array.
