After connecting all the modules with CC-Link dedicated cables, check if the safety remote
I/O stations, standard remote I/O stations and remote device stations are correctly
connected and if a data link is established between them.
Line test 1 checks the status of communication with all modules that have been
connected.
Line test 2 checks the status of communication with specific modules.
Perform the line test according to the following procedure.
(1) Confirm Safety CPU operation mode
Check the LEDs on the safety CPU module to see that TEST MODE is active.
(Confirm that the "TEST" LED is ON.)

the safety CPU module is not in TEST MODE. For how to change to TEST
MODE, refer to the QSCPU User's Manual (Function Explanation, Program
Fundamentals).
(3) Select Line test
In GX Developer, select in order of "Parameter", "Network Parameters", "CC-
Link" to display the "Network parameter CC-Link list settings" screen. On the
screen, set the mode to "Line test" and specify a transmission speed to be
used.
