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 “test all” 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 “all” or “01000000000” 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,
double-check that each node is powered up, is running the Field Network Test
Utility, and has its drop cable or transceiver cable connected.
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.
