3.
Select the master/local module of the network No. 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 No. and station No. 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 No. 2, specify the network No. 1 and station No. 3, or the network
No. 2 and station No. 0 in "Network No." and "Station No.".
• The CC-Link IE Field Network diagnostics can be started for stations of up to four networks ahead (number
of relay stations: 3) including the station directly connected to the engineering tool.
4.
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. (
Page 107 When "No Specification" is specified in "Other Station
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
