Connections
The CIP Connections counters provide global information, and are not related to a specific driver. These counters are not available via RSWho. They are only available from
Communications > CIP Diagnostics
. The following is the list of diagnostic counters shown and the definition of each.Originated connections | Total number of currently open CIP connections originated by RSLinx Classic. |
Bridged connections | Total number of currently open CIP connections originated by an RSLinx Classic client. This count will be zero unless running as an RSLinx Classic Gateway. |
Accepted connections | Total number of currently open CIP connections originated by a network device and accepted by RSLinx Classic. |
Connection open attempts | Total number of CIP connection open attempts processed by RSLinx Classic, either as originator or as target. |
Open attempts rejected | Total number of CIP connection open attempts that were rejected either by RSLinx Classic or by a target network device. |
Connection close attempts | Total number of CIP connection close attempts processed by RSLinx Classic, either as originator or as target. |
Close attempts rejected | Total number of CIP connection close attempts that were rejected either by RSLinx Classic or by a target network device. |
Connections established | Total number of CIP connections successfully established by RSLinx Classic, either as originator or as target. |
Connections closed | Total number of CIP connections closed by RSLinx Classic, either as originator or as target. |
Connections timed out sending | Total number of CIP connections timed out by RSLinx Classic because RSLinx Classic had nothing to send on the connection for the timeout interval specified when the connection was opened. |
Connections timed out receiving | Total number of CIP connections timed out by RSLinx Classic because RSLinx Classic did not receive anything on the connection for the timeout interval specified when the connection was opened. |
Connections dropped | Total number of CIP connections dropped by RSLinx Classic because the application using them was terminated. |
Packet send attempts | Total number of data packets provided to RSLinx Classic for sending on a CIP connection. |
Packets written | Total number of data packets written to a CIP connection buffer. |
Packets overwritten | Total number of data packets written to a CIP connection buffer before a response to the previous packet was received. This is normal behavior if the application using the connection decides it is no longer interested in the response to one request but wants to send a new request. |
Packets sent | Total number of data packets sent on a CIP connection (including retries). |
Packets resent | Total number of data packets resent on a CIP connection because the retry interval expired before a response was received. This may indicate a lost packet or some other communication problem and may be followed by a connection timeout. |
Packets received | Total number of data packets received on a CIP connection. |
Invalid receipts | Total number of connected data packets received that could not be matched to a CIP connection. |
Duplicate receipts | Total number of data packets received on a CIP connection that had the same sequence number as the previous data packet received. A nonzero count may indicate that the retry interval for the connection is too short. |
