Are they the same parts or different parts? Let's say you want to build a system and you want part that reports up to 7 contacts. How do you communicate this to the supplier? The number of contacts - is it controller by the config file you load into the controller, or they have separate parts for different contact count or what? Thanks. -- Dmitry
