Data name Description
NX Unit Error Status 15 This status tells whether an error exists on the NX Units.
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: Error
FALSE: No error
If the Unit configuration information is registered, the status is reported for only
the NX Units for which the NX Unit Registration Status is TRUE (registered). This
status is FALSE for all NX Units for which the NX Unit Registration Status is
FALSE (not registered). If automatic generation
*1
is used for the Unit configura-
tion information, the status is given for all NX Units.
Each bit is set to TRUE when the level of the error is as follows:
•Minor fault
• Observation
The status is FALSE for NX Units that are set as unmounted Units.
Each bit is updated at the following times.
The status changes to TRUE when an error occurs.
The status changes to FALSE when the error is reset. Even if the cause of the
error has been removed, you must reset the error for the status to change to
FALSE.
