Optional blocks (variants)
Optional blocks are used to define the minimum size and the maximum size of a control module
type. The difference between these two states is mapped by the optional blocks. The objective
is to define a control module type so that it can be used as a template for the various control
modules that are similar in function.
When creating the templates, decide which optional blocks to use. The blocks available for a
control module can no longer be changed.
The optional blocks are managed and identified as follows:
● <Project> > @Template > @PCS 7 > Template-Container > CMTs > Control module type>
> <Version of the control module type>
● The variables, together with all of the other control module types, are located in the
"Template-Container" node under "CMT" folder.
● Block (SubCM) in a version of the control module type:
"Automation Interface" tab, "Optional" attribute is activated
