NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
• All tag sets contain eight tags.
• The maximum number of tag sets (32) is registered.
 Specifying Tags
You can specify where to assign a tag either with a variable or with a I/O memory address. However,
some CPU Units may not support both of these methods. Communications with the devices are pos-
sible regardless of whether the remote node tags are set using I/O memory addresses or network
variables.
The supported tag specification methods for each CPU Unit are listed in the table below.
Yes: Supported, No: Not supported
*1 To specify an I/O memory address for a tag, do not specify the I/O memory address for the tag directly. Instead, create a
variable, set an AT specification of the I/O memory address on the Sysmac Studio, and then specify the variable with the
AT specification for the tag.
*2 For an NX1P2 CPU Unit, you need to set CJ memory to use I/O memory address. For details on CJ memory setting, refer
to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501).
