Starting diagnostics
This section describes how to use the CC-Link IE Field Network diagnostics.
■When "No Specification" is specified in "Other Station Setting" on the "Specify Connection
Destination Connection" window
1.
Connect the engineering tool to the CPU module.
If a slave station cannot be monitored due to an error such as cable disconnection, directly connect the supported engineering
tool to the slave station.
2.
Start the CC-Link IE Field Network diagnostics.
[Diagnostics]  [CC-Link IE Field Diagnostics]
In a redundant system, the CC-Link IE Field Network diagnostics cannot be started when a system has been
specified in "Specify Redundant CPU" of "Target System" in the "Specify Connection Destination Connection"
window. Directly connect the engineering tool to the station to be diagnosed, specify the own remote head
module (set "Not Specified" in "Specify Redundant CPU"), and start the CC-Link IE Field Network diagnostics.
3.
When the following window opens, select the master/local module to be diagnosed and click the [OK] button to start the
CC-Link IE Field Network diagnostics.
Modules are listed in the order configured in module information.
When multiple master/local modules of the same network number are mounted on the same base unit, the
module with the smallest start I/O number is always diagnosed, regardless of setting.
