Use of EDESIGN - Basic Concept

Introduction

The structure editor hierarchically displays the module structure of the machine. This also corresponds to the software structure of the machine program.

EDESIGN generates a function block (FB) for every inserted node. The structure or arrangement of the node determines the sequence of the initialization call-ups.

During the program start, the init methods of the modules are called up in the sequence in which the Module tree was structured: from top to bottom and from left to right.

During the cyclic processing of the machine program, the logic methods are also called up in the sequence in which the Module tree has been structured.

The same applies for other methods that were generated from the EDESIGN edition for a module.

Overview of the methods of a module:

oInit

oLogic

oOperating modes, for example, Auto, ...

oIssue error (in global error detection list)

Call-up of your sequence during cyclic execution:

oLogic

oActive operating mode

oIssue error
