4.4.4 Communication test
This test checks whether communications is normally performed between a test-executing station and a
communication-target station (specified with the network number and station number).
If the communication-target station is in another network, the relay network number and station number are displayed
and the routing parameter settings can be checked.
When the communication test is performed from a peripheral connected to the station number 1 in network number 1
to the station number 1 in network number 3 in the system above, the following window appears. The result shows that
communications between two stations is normal.
