WebThe CODESYS software package includes a library with function blocks for communicating with a web server via HTTP or HTTPS. The HTTP method GET requests data from a web server. The HTTP methods POST and PUT submit data from the controller to a web server. When using DELETE, data is deleted from a web server. WebThis is not the case if a method, transition or property of the function block is called, since the VAR_IN_OUT variables of the FB cannot be assigned within a method, transition or property call. Therefore, access to the VAR_IN_OUT variables might occur by calling the method/transition/property before the VAR_IN_OUT variables are assigned to a valid …

WebThe derived function block can overwrite the methods that you have defined in the base function block. This means that the inherited function block can define a method with the same name, the same inputs and the same output as is defined by the basic function block. WebA method contains a declaration and an implementation that includes a series of statements. However, unlike a function, a method is not an independent POU, and it is assigned to a function block or program. You can use interfaces for the organization of methods. You can add a method below a program or a function block.
