Module Diagnostic Objects
The module maintains a set of diagnostic objects, which provide information about the various
module facilities. The information includes current operating status and counts of various module
activities. The diagnostic objects may be especially useful in diagnosing problems with network
performance, PLC access, and similar activities. The diagnostic objects are accessible using a
standard web browser.
Other Troubleshooting Tools
CTIDiag
CTI provides a software program (CTIDiag) that can be used to perform some diagnostic activities.
Although many of the 2572 based functions of CTIDiag are no longer supported by the 2572-A, it
can be used for such functions as setting the module IP address via the serial port and for generating
CAMP message traffic to test the 2572-A server. CTIDiag may be downloaded from the CTI web site
(www.controltechnology.com).
Network Analysis Software
Network analysis software captures Ethernet traffic on a network segment. Once the packets have
been captured, the software decodes the packet information, allowing you to observe the packet
content. In addition, since the packets include a timestamp, you can determine the rate at which
packets are arriving. The network analysis software is especially useful in diagnosing situations
where communications cannot be established or performance is degraded.
8.2. General Troubleshooting Techniques
If you are experiencing problems with using the 2572-A, you should note the general category of the
problem you are encountering:
•
The module has not started up properly. If the Module Status LED is not Steady Green or the
Network Status LED is Off or Steady Red, a problem has been encountered during startup.
•
The module is operational, but is not communicating with a client application.
•
The module is communicating with a client application but performance is substandard.
•
The PLC is unable to initiate a client connection to another CTI Ethernet module (2572- A or
2572 module).
