Meaning
Description
*_UnitSta1
WORD
R
Unit Status 1
Bit 00: Unit Error
Bit 01: Network Error
Bit 04: Unit Memory Error
Bit 05: Communications Controller Error
Bit 06: IP Address Duplication
Bit 09: Link OFF Error
Bit 14: Status Area Layout Setting Error
*_UnitErr
BOOL
R
Unit Error Occurred
TRUE:
An error occurred in the operation of the
EtherNet/IP Unit.
This variable changes to TRUE when any of
the following variables in Unit Status 1
changes to TRUE. (That is, it is an OR of the
status of the following variables.)
*_NetEr
*_UnitMemErr
*_LANHwErr
*_IPAdrDupErr
*_LkOffErr
*_UserStaAreaCfgErr
FALSE: None of the above errors currently exists.
(If any of the errors did occur, it has been
cleared.)
Default: FALSE
*_NetErr
BOOL
R
Network Error
Occurred
TRUE:
There is one or more network-related errors.
(This is an OR of the Communications Sta-
tus 1 and 3 variables. )
FALSE: None of the above errors currently exists. (If
any of the errors did occur, it has been
cleared.)
Default: FALSE
*_UnitMemErr
BOOL
R
Unit Memory Error
TRUE:
An error occurred in accessing the Unit's
internal non-volatile memory (device error).
FALSE: A non-volatile memory error has not
occurred. Once this error occurs, it is not
cleared. (The variable remains TRUE.)
Default: FALSE
*_LANHwErr
BOOL
R
Communications
Controller Error
TRUE:
An error occurred in the communications
controller.
FALSE: A communications controller error has not
occurred. This variable remains TRUE until
the power supply is cycled.
Default: FALSE
