Extensible parameters in function blocks (AC800M)
I would like to create extensible parameters to a function block in the AC800M (Compact Control Builder), where I define the number of parameters of the input/output in question in the declaration pane of the POU editor.
I could not find an example, do you have a template for this functionality?

There is an application for Extensible Parameters for 800xA, please see below link:
I have import that file in to my 800xA system and under Control Builder, saved project as a Compact Control Builer. Finally I have a Extensible Parameters for Compact Control Builder.
If you want, I can share the library for Compact Control Builder.
Hope it helps you.
In order to edit your FB, placed in application, right-click on it -> Edit Type.
Or in the library where the FB is defined - double click on it's name.
The parameters of FB (input/output/in_out direction) are declared in the tab Parameters of the FB - see below.
In the tab Variables you can declare internal FB's variables, which are not visible as external parameters of FB in the application (but you could see these variables from HMI, for example, trough OPC)
After any modifications, choose save and close of FB, then save in application too.
