Figure 40: SMT: Operation principles
A binary input channel can be connected to one or several function block inputs, see
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. Connections made
in ACT are automatically shown in SMT.
It is possible to group and collapse hardware channels in SMT to get a better
overview.
