DF1 Slave 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, and Performance tabs in the tabbed dialog. Driver diagnostics are modeless; therefore, they 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. |
Reply Errors | Number of reply errors. |

Communication Errors with Kernel Driver | Failed calls to RSSERIAL.SYS. |
Canceled Packets | 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. |
