Yes, but what if the manufacturing line is reconfigurable to some
extent? Suppose, for example, that we give wheels and components to
the tools, or that two users (Bryan and Xiaofan) opt to make
installations, and Xiaofan opts to implement his own makeshift arm
that, more or less, follows most of the standards and specifications?
How can this be accounted for? Would a total refactoring of all of the
PLC-programs have to be rewritten? Or could something dynamic be done?
