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 | ||
|
|
| Total number of messages of all types received (ACK, | |
| PLC Message received |
| 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 errors are incremented when the Client side | |
| Protocol |
| 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 | ||
|
|
| ||
|
|
| Client side messages that were not responded to by a | |
| Timeout |
| 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. | ||
|
|
| ||
|
|
| Increments when a ‘status’ response contains a line with | |
| Exception |
| insufficient information for storage but which may be a | |
|
|
| heading. |
