The switch settings of the network module can be checked with this test.
The following three types of items can be checked:
1) Control station duplication check
2) Station number duplication check
3) Matching between the network number set for the station to which GX
Developer is connected and the network number set with a network
parameter of the host
For example, in the following system, when the Setup confirmation test is conducted
by GX Developer connected to station number 1, the monitor screen shown below is
displayed and the setting status of each station can be checked.
Station number 6 displays a duplicate control station setting error, and station numbers
2, 5, 7, and 8 display the network numbers and group numbers because there are no
setting errors.
