Figure 36: SMT: Operation principles
A binary input channel can be connected to one or several function block inputs,
see Figure 37. 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 will automatically also be shown in
ACT.
