 Meanings of Error Status Bits
Note Bits 14 and 15 are never TRUE for the built-in EtherNet/IP port.
Precautions for Correct Use Precautions for Correct Use
Do not use _ErrSta (Controller Error Status) in the user program. There may be a delay in updat-
ing them and concurrency problems may occur with function module error status. Use this vari-
able only to access status through communications from an external device.
 Functional Classification: EtherNet/IP Communications Status
You can check the status of the built-in EtherNet/IP port (e.g., communications status).
Bit Meaning
15 Reserved)
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
_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.

_EIP_EtnOnlineSta Online NY-series Controller: Indicates that the
built-in EtherNet/IP port’s communications
can be used via the communications port
1 (that is, the link is ON, IP address is
defined, and there are no errors).
TRUE: The built-in EtherNet/IP port’s
communications can be used.
FALSE: The built-in EtherNet/IP port’s
communications is disabled due
to an error in initial processing,
restart processing, or link OFF
status.
