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.
