Communications Status with Target Node
The communications status of the Communication Control Unit and the target node is shown by
the combination of the values of the following four system-defined variables.
• _EIP_RegTargetSta (Registered Target Node Information)
• _EIP_EstbTargetSta (Normal Target Node Information)
• _EIP_TargetPLCErr (Target PLC Error Information)
• _EIP_TargetNodeErr (Target Node Error Information)
Value of _EIP_Re-
gTargetSta
TRUE
FALSE
The communications status of CIP communications 1 and CIP communications 2 is shown by the
combination of the values of four system-defined variables in the same way as shown in the above
table.
• CIP Communications 1
• _EIP1_RegTargetSta (CIP Communications1 Registered Target Node Information)
• _EIP1_EstbTargetSta (CIP Communications1 Normal Target Node Information)
• _EIP1_TargetPLCErr (CIP Communications1 Target PLC Error Information)
• _EIP1_TargetNodeErr (CIP Communications1 Target Node Error Information)
• CIP Communications 2
• _EIP2_RegTargetSta (CIP Communications2 Registered Target Node Information)

Meaning
Use the GetNTPStatus instruction to read
the NTP operation information from the
user program.
Direct access is not possible.
Gives the last time that NTP processing
ended normally.
The time that was obtained from the NTP
server is stored when the time is ob-
tained normally.
The time is not stored if it is not obtained
from the NTP server normally.
TRUE: Indicates an NTP normal end.
FALSE: Indicates that NTP operation
ended in an error or has not been execut-
ed even once.

Communications status with
target node
A connection with the target
node was established normally
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-
mally.
The information is not valid be-
cause the target node is not
registered.
