NJ-series Instructions Reference Manual (W502)
• CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (Cat. No. W495)
• 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 2-2 for a timing chart for Execute, Done, Busy, and Error.
• You can use this instruction only through a built-in EtherNet/IP port on an NJ-series CPU Unit or a
port on 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.
• You cannot specify an address in memory for CJ-series Units directly to write data. To write specific
addresses in memory for CJ-series Units, use an AT specification in advance to assign the memory
addresses to a variable.
• You cannot directly specify an address in local memory for CJ-series Units. To write specific
addresses in memory for CJ-series Units, use an AT specification in advance to assign the memory
addresses to SrcDat.
• The characters that can be used in DstDat are specified in the following table.
• An error occurs in the following cases. Error will change to TRUE.
• There is a setting error for the local IP address.
• The text string in RoutePath does not end in a NULL character.
• The value of TimeOut is outside of the valid range.
• The value of Size is outside of the valid range.
• The value of SrcDat is outside of the valid range.
• For this instruction, expansion error code ErrorIDEx gives the CIP message error code. The mean-
ings are as follows:

strings
• Any text string that starts with ASCII characters 0 to 9 (character codes 16#30 to 16#39)
• A text string that consists of only a single _ (underbar) ASCII character
• Any text string that includes two or more consecutive _ (underbar) ASCII characters
• Any text string that starts with an _ (underbar) ASCII character
• Any text string that ends with an _ (underbar) ASCII character
• Any text string that starts with “P_”
Value Error
16#02000000 Normal communications are not possible due to a high load at the remote node.
16#05000000 The specified destination variable does not exist on the other Controller.
16#0C008010 The specified destination variable is being downloaded.
16#0C008011
16#1F000102 The specified destination variable has a Constant attribute, so it cannot be written.
16#20008017 The specified destination variable is not an array and the number of elements to write is not 1.
16#20008018 The specified destination variable is an array and the number of elements to write exceeds the
number of elements in the array.
