Local tags for tag data links can be set using I/O memory addresses or net-
work symbols. Support for network symbols, however, depends on the model
of CPU Unit, as shown in the following table.
Communications with the remote node are possible regardless of whether the
remote node tags are set using I/O memory addresses or network symbols.
Symbols cannot be set for tags with CJ2H-CPU6@ and CJ2M-CPU1@ CPU
Units.
A data link between the local I/O memory and a remote I/O memory is called
a tag. A tag can be set using a network symbol name or an I/O memory
address.
When a connection is established, from 1 to 8 tags (including PLC status) is
configured as a tag set. Each tag set represents the data that is linked for a
tag data link connection. Tag data links are thus created by connecting one
tag set to another tag set. A tag set name must be set for each tag set.
A connection is used to exchange data as a unit within which data concur-
rency is maintained. Thus, data concurrency is maintained for all the data
exchanged for the tags in one data set.
In the following example, input tags a to g at the originator are a tag set
named SP1_IN and output tags i and ii are a tag set named SP1_OUT). A
connection is set between these two tag sets.
