A binary input channel can be connected to one or several function block inputs, see
Figure 41. If a 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.
Connections made in SMT are automatically shown in ACT.

It is possible to group and collapse hardware channels in SMT to get
a better overview.

Depending on the IED capability, SMT has a separate sheet for each possible
combination.
