Connecting signals in SMT

SMT is used to do cross references, see
• between physical IO signals and function blocks.
• for the GOOSE engineering.

Figure 39: SMT: Operation principles
A binary input channel can be connected to one or several function block inputs, see
binary input channel is connected to several different function blocks in ACT, the connection will
appear as glue logic in SMT.
A binary output channel can only be activated from one function block output. If it should be
activated from more than one function block output, glue logic has to be used. Glue logic means
inserting a logical gate (OR and AND blocks) between the function blocks and the binary output
channel. This can be engineered in SMT.
