Mitsubishi Electric MELSEC iQ-R Series User Manual page 172

When starting the CC-Link IE TSN/CC-Link IE Field diagnostics by specifying "Other Station (Single Network)"
or "Other Station (Co-existence Network)" in "Other Station Setting" on the "Specify Connection Destination
Connection" window, the following restrictions apply.
• A communication test cannot be used.
• A station information list cannot be used.
• If MELSECNET/H, multidrop connection of serial communication modules, an interface board for personal
computer, a GOT (FA transparent function used), or network modules of the MELSEC-Q/L series are
included in the communication path, diagnostics cannot start.
When "Other Station (Co-existence Network)" is specified in "Other Station Setting" on the "Specify
Connection Destination Connection" window and "CC-Link" or "C24" is specified in "Co-existence Network
Route", diagnostics cannot start.
When starting the CC-Link IE TSN/CC-Link IE Field diagnostics by specifying "Other Station (Single Network)"
or "Other Station (Co-existence Network)" in "Other Station Setting" on the "Specify Connection Destination
Connection" window, 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 TSN/CC-Link IE Field 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.".
• Although the CC-Link IE TSN/CC-Link IE Field 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.
• The CC-Link IE TSN/CC-Link IE Field 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.
