9.14.2 Test run execution procedure

1. Automatic I/O number assignment (CONFIG mode)
Check the automatic assignment operation using the following procedure.
1
Connecting all cables
Connect all CC-Link/LT components (remote I/O units, power supply adapter, dedicated power
supply, terminating resistors, etc.) with dedicated flat cables.
2
Setting the station number of remote I/O units
Set the station number of remote I/O units.
3
Setting the transmission speed, number of points and station number of the
built-in master
