The CIP Status window provides information about Control Industrial Protocol (CIP)-related status (Overview) and statistics (Request Details) since the switch was last powered on, was restarted, or the counters were last reset. CIP is a messaging protocol that defines how various industrial automation and control devices, systems, and applications come together to form an industrial automation and control system. CIP with EtherNet/IP provides application-level connections from the switch to the industrial devices in the network. It enables the switch to work with the industrial automation and control system for basic management and monitoring. The Overview area displays the state of the CIP connection to the switch. CIP Status | The state of the CIP connection. This field displays either Enabled or Disabled. | CIP I/O Connection Owner | The IP address of the device to and from which application-specific I/O output data is sent. | CIP Config Session Owner | The IP address of the device that controls the CIP configuration session. | Management CPU Utilization (%) | The CPU usage for the CIP configuration session owner. | Active Explicit Msg Connections | The number of active explicit message connections (generic, multipurpose communication) between devices. | Active I/O Connections | The number of active application-specific connections (special-purpose communication) between a producing application and one or more consuming applications. | Active Multicast Groups | The number of multicast groups, including the CIP multicast group, configured on the switch. | Forward Open Requests Received | The number of Forward Open requests received by the switch to establish a conection with an industrial device in the network. | Forward Open Requests Rejected Due to Lack of Resources | The number of Forward Open requests that failed for reasons such as insufficient memory to establish a new connection. | Forward Open Requests Rejected Due to Format | The number of Forward Open requests that failed because the request is not in the proper format. | Forward Open Requests Rejected for Other | The number of Forward Open requests that failed for reasons such as incompatible electronic keying. | Forward Close Requests Received | The number of Forward Close requests received by the switch after a connection is successfully established with an industrial device in the network. | Forward Close Requests Rejected Due to Format | The number of Forward Close requests that failed because the request is not in the proper format. | Forward Close Requests Rejected for Other | The number of Forward Close requests that failed for reasons such as incompatible electronic keying. | Connection Time Outs | The number of CIP sessions that timed out due to inactivity. | Back to the top To troubleshoot a problem, clear the CIP counters, and see if the counters show that the problem still exists.
