The meanings of the bits are shown in the following table. However, do not use the following varia-
bles in the user program:
_ErrSta
(Controller Error Status),
_CJB_ErrSta
(I/O Bus Error Status),
_CJB_MstrErrSta
(I/O Bus Master Error Status),
_CJB_UnitErrSta
(I/O Bus Master Unit Status),
_NXB_ErrSta
(NX Bus Function Module Error Status),
_NXB_MstrErrSta
(NX Bus Function Module
Master Error Status), and
_NXB_UnitErrStaTbl
(NX Bus Function Module Unit Error Status). There
may be a delay in updating them and concurrency problems in relation to the error status of the
function module. Use these variables only to access status through communications from an exter-
nal device.

15
Master-detected error: This bit indicates whether the master detected a Controller error in the Unit/slave for
the error status of the Controller error.
TRUE: The master detected a Controller error.
FALSE: The master has not detected a Controller error. (Valid for
_CJB_UnitErrSta
.)
14
Collective slave error status: This bit indicates if a Controller error was detected for levels (e.g., a Unit, slave,
axis, or axes group) that are lower than the event source (i.e., for a function module).
TRUE: A Controller error has occurred at a lower level.
FALSE: A Controller error has not occurred at a lower level. (Valid for
_CJB_ErrSta
,
_MC_ErrSta
, and
_EC_ErrSta
.)
8 to 13
Reserved.
7
This bit indicates whether a major fault level Controller error has occurred.
TRUE: A major fault level Controller error has occurred.
FALSE: A major fault level Controller error has not occurred.
6
This bit indicates whether a partial fault level Controller error has occurred.
TRUE: A partial fault level Controller error has occurred.
FALSE: A partial fault level Controller error has not occurred.
5
This bit indicates whether a minor fault level Controller error has occurred.
TRUE: A minor fault level Controller error has occurred.
FALSE: A minor fault level Controller error has not occurred.
4
This bit indicates whether an observation level Controller error has occurred.
TRUE: An observation level Controller error has occurred.
FALSE: An observation level Controller error has not occurred.
0 to 3
Reserved.
Note
Bits 14 and 15 are never TRUE for the built-in EtherNet/IP port.
