Troubleshooting

This section describes some of the problems you may encounter with the Ethernet network, RS-422 (Siemens 3964R) interface and the Application Program Interface (API), and gives brief descriptions of how you might attempt to solve each problem.

Ethernet Network

When the Ethernet network needs troubleshooting, you can:

•Refer to Testing the Ethernet Network in Chapter 5. Setting Up the Ethernet to find out how to use the ping command through Hyperterminal or Telnet applications.

•Refer to Table 3-1on page 3-15for a list of LEDs that exist on the Ethernet interface card within the CS4000 Mini Controller.

•Use the TINI Ethernet Flash Utility to modify the Ethernet interface card application settings and disable unnecessary functions (the latter may help if the troubleshooting problem is related to thru-put performance.) To find out how to update the application settings, refer to Updating Application Settings in Chapter 5. Setting Up the Ethernet.

Table 8-2describes some common problems of the Ethernet network and TINI Ethernet interface card, and gives possible solutions for each problem.
