5-7 D: Broadcast Test
“D: Broadcast test” is used to broadcast a communications test from the Control-
ler Link Support Software to all the nodes participating in the specified network.
In a broadcast test, the Controller Link Support Software simultaneously trans-
mits the specified bytes of test data to all nodes the specified number of times.
After test data has been transmitted, the Controller Link Support Software moni-
tors the number of times the test data has been received by each node and de-
termines the success count for each node. (The contents of each received test
data will not be checked.) If the success count differs from the number of tests
conducted for a node, the node has communications problems.

sor Keys to move the cursor to the desired field, then enter a numeric value
