*2 Use this variable name for port 1 on an NX-series CPU Unit, or for an NY-series Controller.
*3 Use this variable name for port 2 on an NX-series CPU Unit.
*4 Use this variable name for the internal communication port on an NY-series Controller.
Additional Information
• Refer to the following manuals for details on CIP communications.
• NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506)
• NY-series Industrial Panel PC / Industrial Box PC Built-in EtherNet/IP Port User's Manual (Cat.
No. W563)
• CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (Cat. No. W495)
• To use Large_Forward_Open as the class 3 connection service, you can also use the CIPOpen
instruction (page 2-990).
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 (page 2-3) for a timing chart for Execute, Done, Busy, and Error.
• You must execute this instruction or the CIPOpen instruction before you execute the CIPRead, CIP-
Write, or CIPSend instruction.
• For this instruction, the first timeout time after a connection is established is 10 s even if the value of
TimeOut is set to less than 100 (10 s).
• Use the CIPClose instruction to close connections that were opened with the CIPOpenWithDataSize
instruction.
• Even if the connection times out, the handle created by this instruction will remain. Always use the
CIPClose instruction to close the connection.
• Handles that are created with this instruction are disabled when you change to PROGRAM mode.
• You can create a maximum of 32 handles at the same time.
• 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.
• An error occurs in the following cases. Error will change to TRUE.
• The value of TimeOut is outside of the valid range.
• The text string in RoutePath is not valid.
• More than 32 CIP-related instructions were executed simultaneously.
• An attempt was made to open a connection beyond the CIPClass connection resources (32 con-
nections).
• A connection opened response was not received.
• The value of DataSize is 510 to 1,994 and the remote node to which to open a connection does
not support Large_Forward_Open.
• There is a setting error for the local IP address.
• A duplicated IP error occurred.
• All TCP connections are already in use.
• The instruction was executed when there was a BOOTP server error.
