Driver Operating and Error Statistics

These notes outline driver specific use of the normal driver operating stats documented in the FieldServer
Configuration Manual.

Timeouts: During normal polling a timeout can mean that the field device did not respond to the select
message (or the sub-device select message) or did not respond to the poll for data or the command poll.

Exception Stats: If the driver selects a device, sub-device or port and the return code from the device is
unexpected the this stat is incrmented by 1.

Ignored Stats: If the current record is read and there is more data than can be stored than specified by the
Length of the Map Descritor then this stat is incremented and message MET1#05 is printed. If a poll is
received for the current record but there isn’t one available, the device sends a response which also
increments the ignored stat but in this case there is no additional message printed in the error log.

The driver does not use the normal operating stats to count message and bytes received in response to
select / sub select messages.
