Procedure 5: Testing the Ethernet Interfaces on the Network

This procedure shows you how to verify operation of the physical network to provide the necessary foundation for reliable communications.

This procedure will ensure that:

HThe cable plant is functional,

HThe physical connection of each node is functional,

HAll transmission paths meet or exceed the expected low bit error rate.

When you are testing the network, be sure there is an adequate explanation for any- thing unusual. Logging of exceptions should be the exception, not the rule. Properly setup nodes and networks can run for long periods (weeks or months) without logging exceptions.

Field Network Test Utility

This section describes the use of the Field Network Test Utility that is built into the

Ethernet Interface.

All software and configuration needed to perform these tests is contained in the Ether- net Interface as it is shipped from the factory. You do not need to download the commu- nications software from the GSM for these tests, however, you may optionally change Soft Switch parameters as described previously. (However, if you have loaded commu- nications software, the Field Network Test Utility will still operate properly, and the soft- ware you loaded will be preserved.) The default parameters provided will work on any network with up to 50 nodes. For larger networks, consult GE Fanuc Automation ± NA if you need assistance to determine how to test your network.

Note

After you have established confidence in your particular application and configuration parameters, you can periodically re±test your physical network while the applications are running. This is done by using the TEST Station Manager command, but without invoking the Field Network Test Utility. All the Station Manager commands available in Field Network Test Utility are also available when the Ethernet Interface is fully operational.
