Appendix C.2. Standard Driver Stats

Driver Statistics Recorded

Explanation

PLC Read Messages sent

Number of message sent to the Gage

PLC Write Messages sent

Should be zero

PLC Bytes sent

Total number of bytes sent by the Client side driver

PLC Message received

Total number of messages of all types received (ACK,
NAK, error response, normal response) on the Client side
driver.

PLC Bytes received

Total number of bytes received by all message types on
the Client side driver.

Protocol

Protocol errors are incremented when the Client side
cannot correctly parse a response message from the
Gage. This includes responses that are formatted
differently from what the driver expects, or messages that
report the Gage is ‘unable’ or in setup mode.

IC_Timeout

Incoming message buffer experiences an excessive
delay between incoming bytes

Timeout

Client side messages that were not responded to by a
Server. Possibly a communications error or a command
was made to a unit that does not exist.

Streaming

Message size was too large for the input buffer. This
should never occur.

Exception

Increments when a ‘status’ response contains a line with
insufficient information for storage but which may be a
heading.
