ACT: Concept of Execution order sequence
In the conceptual MainApplication example in
the main function block in the execution order group 2 defines the execution orders
needed in group 1 and 3. The preceding logic done with function blocks in group 1
must have a lower execution order than the ones in group 2. The following function
blocks in group 3 must have a higher execution order than the main function block
in group 2.

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 base
attribute type, see
.
