You can use automatic detection of the tag set names that are set for devices to automatically set con-
nections between input and output tag sets with the same name (or the same names excluding speci-
fied ellipses). Connections are automatically set under the following conditions.
Example 1: Automatic Connections with the Same Tag Set Names
The following connections are automatically set with the same tag set name (A_Signal) if there is an
output (produce) tag set named A_Signal at node A and input (consume) tag sets named A_Signal
at nodes B and C.
Example 2: Automatic Connections with the Ellipses
The following connections are automatically set with the same tag set name (Signal) if there is an
output (produce) tag set named O_Signal at node A and input (consume) tag sets named I_Signal
at nodes B and C, and “O_” and “I_” are set as forward ellipses.

Output tag set names for connec-
tion setting
Except for specified ellipses, the output tag set name must be the same as
the input tag set name. Ellipses can be set for the beginning or end of tag
set names.
Input tag set names for connection
settings
Except for specified ellipses, the input tag set name must be the same as
the output tag set name. Ellipses can be set for the beginning or end of tag
set names.
Connection type The connection type must be Input Only. Multi-cast or single-cast connec-
tions can be specified for a connection.
RPI The default setting is used.
Timeout The default setting is used.
