3.
Select the master/local module of the network number to be diagnosed and click the [OK] button to start the CC-Link IE
Field Network diagnostics.
• Although the CC-Link IE Field Network diagnostics of the network to which the relay sending station
belongs can be started, that of the network to which the relay receiving station belongs cannot be started.
• To start the CC-Link IE Field Network diagnostics, specify the network number and station number of the
relay receiving station or relay sending station for "Network No." and "Station No." in "Network
Communication Route" on the "Specify Connection Destination Connection" window. For example, to start
the CC-Link IE Field Network diagnostics of the network number 2, specify the network number 1 and
station number 3, or the network number 2 and station number 0 in "Network No." and "Station No.".
• The CC-Link IE Field Network diagnostics can be started for stations of up to eight networks ahead (number
of relay stations: 7) including the station directly connected to the engineering tool. However, for the stations
of five networks ahead (number of relay stations: 4) or later, it can be started only when the firmware version
of the master/local module is "18" or later.
• The selected station communication status monitor of the RJ72GF15-T2 cannot be executed in the CC-Link
IE Field Network diagnostics for the stations of five networks ahead (number of relay stations: 4) or later.

Step 4 and later is the same procedure as when "No Specification" is specified in "Other Station Setting" on the "Specify
Connection Destination Connection" window. (

Setting" on the "Specify Connection Destination Connection" window)
Precautions
If the communication path includes the following items, the CC-Link IE Field Network diagnostics cannot be started.
• MELSECNET/H
• Multidrop connection with a serial communication module
• Interface board for a personal computer
• GOT (when the transparent function is used)
• MELSEC-Q/L series network module
