7-3 Ladder Programming for Tag Data
Links
If data in the ladder program is linked by tag data links, add conditions 1 to 3 in the ladder program for
that data. If you want to use target node Controller information in the input conditions, add conditions 4
and 5.
 Conditions to enable the NY-series Built-in EtherNet/IP Port’s tag data links:
(1) The following error bits in the Built-in EtherNet/IP Error variable ( _EIP_ErrSta ) are
FALSE.
Major fault: Bit 7,
Partial fault: Bit 6,
and Minor fault: Bit 5
(2) Also, the Online variable ( _EIP_EtnOnlineSta )
*1
is TRUE.
 Conditions showing that connections are established with the target device,
and tag data links are operating:
(3) The bit corresponding to the target node address in the Normal Target Node Informa-
tion variable ( _EIP_EstbTargetSta ) is TRUE.
 Condition for the Controller operating mode (operating or stopped) of the
target node (valid for OMRON Controllers only):
(4) The bit corresponding to the target node address in the Target PLC Operating Mode
( _EIP_TargetPLCModeSta ) is TRUE.
 Condition for the Controller error status (fatal or non-fatal error) of the target
node (valid for OMRON Controllers only):
(5) The bit corresponding to the target node address in the Target PLC Error Information
( _EIP_TargetPLCErr ) is FALSE.
When you want to use the Target Node Controller Error Flag, the Controller status must be
included in the tag sets for both the originator and target. Include the Controller status by
using the Network Configurator to select the Include Options in the Edit Tag Set Dialog
Boxes.
*1 Replace this with the following variable name, depending on which port you use.
Built-in EtherNet/IP port: _EIP1_EtnOnlineSta
Internal port: _EIPIn1_EtnOnlineSta
