Controller Communications with NX Bus

NX bus communications can be used when the controller is an NX-series CPU Unit. In this case, only
the NX-type IO-Link Master Unit can be used.
For whether an NX Unit can be connected to the CPU Unit, refer to the user's manual for the CPU
Unit.
Using an NX-series CPU Unit as the Controller
The following figure shows a system configuration when the IO-Link Master Unit is connected to an
NX-series NX1P2 CPU Unit.
Refer to the user's manual for the connected CPU Unit for system configurations and corresponding
versions of Support Software if the connected CPU Unit is not an NX1P2 CPU Unit.
