Evaluation of networks in FBD and the FBD-elements
The order in which →networks in the FBD-editor and their FBD-elements are →evaluated is not necessarily the same as the order as they are positioned. Similarly, it is not necessary that all networks be evaluated before the evaluation of a given network can be repeated.
When the networks and their elements are evaluated, Neuron Power Engineer applies the specifications of the →IEC-standard. However, if the IEC-standard does not specify details for continuing the evaluation, specifications internal for Neuron Power Engineer are applied. This section informs you about all rules applied. |
Mind the following:
-
If there are several networks within the FBD-editor, first Neuron Power Engineer determines a network to be evaluated. See "Order of networks in FBD".
-
For this network to be evaluated, Neuron Power Engineer determines the order of the statements to be evaluated. See "Order of statements within an FBD-network".
When you are showing the execution order, you see the order of the statements to be evaluated. -
The evaluation of the SFC elements is the result of the order of the SFC elements and of specified rules of evolutions. See "Evaluating SFC elements".
