*2 To use a data size of 505 to 1,444 bytes, the system must support a large forward open (an optional CIP spec-
ification). The SYSMAC CS/CJ-series Units support a large forward open, but before you connect to nodes of
other companies, confirm that those devices also support it.
*3 Here, pps means “packets per second” and indicates the number of packets that can be processed in one sec-
ond.

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
* 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.
