Figure 36: 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.

Configuration parameters

Configuration parameters are found in the parameter setting tool. For example, the
SMAI function block has to be configured to support AC-current values or AC-
voltage values.

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 Figure 37.
