DF1 Polling Master Driver diagnostics
Diagnostic counters are available by right-clicking the processor station in the
RSWho
window. Driver diagnostics are found under the General
, AB Diagnostic Counters
, Error Counters
, and Performance
tabs in the tabbed dialog box. Driver diagnostics are modeless, and can remain on the desktop if you minimize RSLinx Classic. The following is the list of diagnostic counters shown and the definition of each.General Tab | |
|---|---|
Command Packets Mailed | Solicited messages placed in the driver queue for transmission. |
Reply Packets Received | Reply packets received from slave stations. |
Unsolicited Replies Mailed | Unsolicited reply packets placed in the driver queue for transmission. |
Unsolicited Messages Received | Total number of unsolicited messages/commands received from stations on the same link as this one (local stations). These are messages that are sent to RSLinx Classic that are not sent to an RSLinx Classic virtual link. |
Fake Packets Handled | Diagnostic packets sent to the driver and replied to. |
Total Bad Packets Received | Bad/Unsupported packets received from kernel driver. |
Unmatched Reply Packets | The number of times a reply packet was received by RSLinx Classic to which there was no associated pending packet. |
Bad Packets | Bad/Unsupported packet received from RSLinx Classic engine. |
Timeouts | Total commands for which no response was received before the specified timeout period. |
Communication Errors with Kernel Driver | Failed calls to RSSERIAL.SYS. |
Packets Canceled | Total number of connected packets and unconnected requests sent that the RSLinx Classic engine attempted to cancel due to a timeout or an application or connection termination. If a response to a canceled request is received at a later time, it is disregarded. |
Packets in Queue | Packets in the user-mode queue waiting to be sent to the kernel driver. |
Unsolicited Packets in Queue | Unsolicited packets in the user-mode queue waiting to be sent to the kernel driver. |

Unexpected CRC Error | CRC checksum failed on a packet received. |
Failed To Transmit Message | The message failed to transmit. |
Retransmit Timeouts | A packet timed out waiting to be retransmitted. |
