11-2 NX Unit Mounting Settings
This section describes the NX Unit mounting function when the disabled setting is used.
The disabled setting is used to register NX Units that are not connected to the actual configuration but
will be added at a later time in the Unit configuration information as unmounted Units.
If you use this function, you do not have to modify the user program after the NX Units are added
because of the following reasons.
• IO memory area is reserved for these unmounted NX Units in the same way that it is reserved for
mounted NX Units.
• Unmounted NX Units are also assigned NX Unit numbers. This prevents the NX Unit numbers of
other NX Units in the same IO Device Terminal from changing when you change the setting of an NX
Unit from unmounted to mounted.
