Configuration parameters
Connections and variables
A connection is the link or "wire" between function block outputs and inputs.
Rules and methods to do connections:
•
Drag a line between two signals.
•
Link two signals by using variables.
It is possible to search and replace variable names in ACT.
Connection validation
A connection is only useful and possible between two signals of the same data
type, see

Hardware channels
Hardware channels can only be connected to a function block input or output. A
hardware connection can be established in ACT or SMT. When a hardware channel
is connected a graphical symbol appears in ACT, see
