Figure 60: Signal Matrix: operation principles
A binary input channel can be connected to one or more function block inputs. If a
binary input channel is connected to several different function blocks in the
Application Configuration tool, the connection appears as glue logic in Signal Matrix.
A binary output channel can only be activated from one function block output. If it is
activated from more than one function block output, the glue logic has to be used.
Glue logic means inserting a logical gate (OR and AND blocks) between the binary
input and the function blocks or between the function blocks and the binary output
channel. This can be engineered with Signal Matrix.
