Precautions for Correct Use
• Execution of this instruction is continued until processing is completed even if the value of Execute
changes to FALSE or the execution time exceeds the task period. The value of Done changes to
TRUE when processing is completed. Use this to confirm normal completion of processing.
• Refer to Using this Section on page 2-3 for a timing chart for Execute, Done, Busy, and Error.
• Execute the CIPOpen or CIPOpenWithDataSize instruction to obtain the value for Handle before you
execute this instruction.
• Always use a variable for the input parameter to pass to ServiceDat. A building error will occur if a
constant is passed.
• You can use this instruction only through an NJ/NX-series CPU Unit, through a built-in EtherNet/IP
port on an NY-series Controller, or through an EtherNet/IP Unit connected to an NJ-series CPU Unit.
• If a variable is written to an OMRON Controller, the variable must be published to the network. Pub-
lish the variable to the network in advance.
• An error occurs in the following cases. Error will change to TRUE.
• A value that is out of valid range is set for RqPath.ClassIDLogicalFormat or RqPath.AttributeID-
LogicalFormat.
• A mismatch occurred between the following two variables: the size specified for RqPath.ClassID-
LogicalFormat and the data size of RqPath.ClassID, the size specified for RqPath.InstanceIDLog-
icalFormat
RqPath.AttributeIDLogicalFormat and the data size of RqPath.AttributeID.
• The value of Size exceeds the write data range.
• The value of Size exceeds the range of ServiceDat.
• The value of RespSize exceeds the range of RespServiceDat.
• A data type that is not supported was specified for ServiceDat.
• A data type that is not supported was specified for RespServiceDat.
• A variable whose data type is other than _sREQUEST_PATH or _sREQUEST_PATH_EX is spec-
ified for RqPath.
• An error response defined by CIP was returned.
• The value of Handle.Handle is outside of the valid range.
• More than 32 CIP-related instructions were executed simultaneously.
• The connection that was established with the CIPOpen or CIPOpenWithDataSize instruction has
timed out.
• The total of the sizes of RqPath and ServiceDat exceeded the data size determined by the
instruction that established the connection.
Sample Programming
Refer to the sample programming that is provided for the CIPOpen instruction (page 2-990).
