3.8 Network Diagnostics from the Peripheral Device (Online Tests)
With the network diagnostic function of GX Developer, the line status can easily be
checked and diagnosed.
To conduct the network diagnostics, the network parameters (station number switch,
mode switch, number of module cards, network settings, and common parameters)
must be set. However, even if all the parameters were not set, the loop test can be
performed while the "T.PASS" LED is on.
The network diagnostics function allows the diagnostics of the network module while
maintaining it in the online status when a problem occurs during the system operation.
For details on the operations of each function, see the GX Developer Operating
Manual.
