A-3-7 Meanings Of Error Status Bits - Omron NJ-series User Manual

Additional Information
Communications Status with Target Node
The communications status with the target node of an NJ-series Controller is shown by the com-
bination of the values of four system-defined variables, _EIP_PegTargetSta (Registered Target
Node Information), _EIP_EstbTargetSta (Normal Target Node Information), _EIP_TargetPLCErr
(Target PLC Error Information), and _EIP_TargetNodeErr (Target Node Error Information), as
shown in the following table.

A-3-7 Meanings of Error Status Bits
The meanings of the individual bits in the following error status are the same.
• _ErrSta (Controller Error Status)
• _PLC_ErrSta (PLC Function Module Error Status)

TRUE
FALSE Disabled
Disabled Disabled
Meaning
Change this variable to TRUE to start tag
data links.
It automatically changes back to FALSE
after tag data link operation starts.
Note Do not force this switch to change to
FALSE from the user program or from
the Sysmac Studio. It changes to
FALSE automatically.
Change this variable to TRUE to stop tag
data links.
It automatically changes back to FALSE
after tag data link operation stops.
Note Do not force this switch to change to
FALSE from the user program or from
the Sysmac Studio. It changes to
FALSE automatically.

Value of
status with target
node
A connection with
the target node was
established nor-
mally and there is
no error in the tar-
get PLC.
A connection with
the target node was
established but
there is an error in
the target PLC.
A connection with
the target node was
not established nor-

The information is
not valid because
the target node is
not registered.
