Additional Information
Refer to the NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506) or NY-
series Industrial Panel PC / Industrial Box PC Built-in EtherNet/IP Port User's Manual (Cat. No. W563)
for details on socket services.
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.
• This instruction can be used only for the built-in EtherNet/IP on NJ/NX-series CPU Units and NY-
series Controllers.
• Up to 2,000 bytes of data can be sent with one instruction. A maximum of 2,000 bytes is sent even if
the SendDat[] array is larger than 2,000 bytes.
• Data is not sent if the value of Size is 0.
