1784-PCMK diagnostics
To access the diagnostic counters, in the
RSWho
window, right-click the processor station. Driver diagnostics are found under the General
, Performance
, MAC Driver Counters
, and DH+ Counters
tabs in the tabbed
dialog box. river diagnostics are modeless, and can remain on the desktop if you minimize RSLinx Classic. The following is the list of diagnostic counters and the definition of each.General Tab | |
|---|---|
Total Solicited Packets Sent | The total of Local Solicited Packets Sent and Remote Solicited Packets Sent. |
Solicited Replies Received | Total replies received to both local and remote solicited packets sent. This number should equal Total Solicited Packets Sent, but lags behind by a few packets because replies are not back yet. |
Local Unsolicited 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. |
Remote Unsolicited Received | Total number of unsolicited messages/commands received from stations on remote (offlink) links or messages/commands that are sent to an RSLinx Classic virtual link. |
Unsolicited Forwarded | Total number of unsolicited messages forwarded to the RSLinx Classic engine from the driver. This number should equal the total of Local Unsolicited Received and Offlink Unsolicited Received. |
Unsolicited Replies Sent | Total number of unsolicited messages that the RSLinx Classic engine replied to. This number usually equals Unsolicited Forwarded unless RSLinx Classic gets unsolicited messages that it does not understand and cannot forward to a client application or cannot reply to. |
Communication Errors | Total number of errors communicating from the RSLinx Classic engine to the actual device driver to specifically send a packet out. This number should never increase beyond zero. If it does, the actual drivers and/or communication interface hardware are being stressed beyond their capacity. |
Solicited Packets Canceled | Total solicited packets that timed out in RSLinx Classic waiting for a reply. If a reply is received at a later time, the reply is disregarded. If this number is rapidly, this driver and/or communication interface hardware is being stressed beyond its capacity. |
Local Solicited Packets Sent | Total packets sent to local stations on the local link and not on the other side of any bridge. |
Remote Solicited Packets Sent | Total packets sent to remote stations on a remote link (the other side of a bridge). |
Local Unsolicited Replies Sent | Total number of local unsolicited replies sent. |
Remote Unsolicited Replies Sent | Total number of remote unsolicited replies sent. |
Performance Tab | |
|---|---|
Sent packets/second | Total packets sent (solicited and unsolicited) per second by user-mode driver. |
Received packets/second | Total packets received (solicited and unsolicited) per second by user-mode driver. |
MAC Driver Counters | |
|---|---|
Packets From Protocol Driver | Packets from the protocol driver. |
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 To Protocol Driver | Packets to the protocol driver. |
Total ISR Calls | Total ISR calls. |
Total DPC Calls | Total DPC calls. |
Total Polled DPC Calls | Total polled DPC calls. |
Failed IndicateReceive () | Failed IndicateReceive (). |
Zero Length Packets Rcvd | Zero length packets received. |
Send Queue Size | Send queue size. |
