Data name Description
NX Unit Registration Status
15
This status tells whether the NX Units are registered in the Unit Configuration.
The status is acquired for as many NX Units as the numeric suffix at the end of
the data name. Select the I/O data with the appropriate numeric value based on
the number of NX Units that are mounted.
This status is given as an array of BOOL data. The subscript of the array corre-
sponds to the NX Unit number. A subscript of 0 indicates the EtherNet/IP Coupler
Unit.
Each bit has the following meaning.
TRUE: Registered
FALSE: Not registered
If the Unit configuration information is registered, the status is TRUE for each Unit
that is registered.
If the Unit configuration information was automatically created (with only the
actual Unit configuration information and no registered information), the status is
FALSE for all Units.
The status is TRUE for NX Units that are set as unmounted Units.
Each bit is updated at the following times.
• If the Unit Configuration Information Is Registered:
The status changes to TRUE when the system is started.
The status changes to FALSE when the configuration information is cleared.
• If the Unit Configuration Information Is Automatically Created:
The status changes to TRUE when the configuration information is confirmed.
The status is always FALSE if the Unit configuration information is automati-
cally created.
