Appendix A. Driver Error Messages
Message Description
MET1:#01 Err. Cant set mode to
state=%d for MD=%s
An attempt was made to send a mode control command to
a device. The required mode is derived from the Data
Array value. This message is printed when the driver
doesn’t recognize the value found and thus cannot send
the command. This can be resolved by having the
upstream device send a valid value to the DA:offset
associated with the reported MD. Refer to the example in
section 4.9 for more information.
MET1:#02 Err. Cant set Sample
time to zero. MD=%s
The reported Map Descriptor is being used to send a new
Sample Time to the field device but the time found in the
Data Aarray:offset specified on the Map Descriptor is zero.
The driver cannot send a sample time of zero. This can be
resolved by by having the upstream/other protocol send a
non-zero value to the DA:Offset.
MET1:#03 Err. Cant set Holde
time to zero. MD=%s
The reported Map Descriptor is being used to send a new
Hold Time to the field device but the time found in the Data
Array:offset specified on the Map Descriptor is zero. The
driver cannot send a sample time of zero. This can be
resolved by by having the upstream/other protocol send a
non-zero value to the DA:Offset.
MET1:#04a/b Err. Invalid time
string=%s MD=%s
Message 4a is printed when a response to a poll for the
Sample/Hold time returned a response whose time cannot
be correctly understood by the driver. If this error occurs
rarely it may be a consequence of an occasional
corruption. If it occurs consistently, take a log, ensure this
event occurs at least once during the log and contact Tech
Support. The FieldServer web site provide tools and
instructions for taking logs.
Message 4b is printed when the time is formatted correctly
but found be an invalid time. The same considerations
apply as with 4a.
MET1:#05 FYI. MD=%s too short
to store all. Ignored stat
incremented each time this
happens. Play safe - set MD
length=20.
This message is printed once and trhen suppressed.
The Map descriptor is not long enough to store all data
from the record..

Refer to section 4.11.
MET1:#06 Err. Cant store Current
Record. Chksum err.
If a response to a read Current Record contains a
checksum error the driver prints this message.
If this error occurs rarely then it may be a consequence of
an occasional corruption. If it occurs consistently, take a
log, ensure this event occurs at least once during the log
and contact Tech Support. The FieldServer web site
provide tools and instructions for taking logs
