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.
