Running Field Network Test
Once all stations are running the Field Network Test Utility, you will use the Station Manager to run tests to verify that the cable plant is operating correctly and to examine statistics about network performance.
The procedure below describes the steps to be performed for the Field Network Test.
1.Select a station to be the test initiator and connect the GSM to this station. This may be any Ethernet Interface. If your application uses a particular node to communicate with most others, we suggest you designate this node as the test initiator.
Note
All commands described in this procedure are issued from your test initiator.
2.Enter the command:
$ | test | all | : | Lists all nodes on operating network. |
or |
|
|
|
|
$ | test | 010000000000 | : | Lists all GE Fanuc nodes on operating network. |
The response to ªtest allº will return a list of the MAC addresses of all nodes attached to the network and presently operating. (This list may include other vendor's nodes since the standard IEEE 802.2 test response mechanism is used. Testing other vendor's nodes is, however, beyond the scope of this procedure. Ignore responses from these nodes.)
Caution
Using either of the addresses ªallº or ª01000000000º to access stations on the network is recommended only under controlled test conditions. Execution of Station Manager commands on an operational network using these addresses may generate a great deal of traffic and might degrade network or node performance temporarily.
Compare this list with the nodes in the network. If all expected nodes are not listed,
Correct any deficiencies and repeat steps 1 and 2 until all nodes to be tested are in the response list.
This procedure assumes that all stations attached to the network remain either powered or not powered continuously from step 2 through step 6. Turning any node(s) ON or OFF or Restarting any node during this test will artificially inflate the error count.
