Hi, Eric Lifsey explains to me in a separate Email today: "On page 11 (of EN61326), at the top, the first paragraph seems to be clear about the exception for I/O ports that employ shielded cables. It overrides any discussion of shielded cables in -4-6."
Please allow me to quote the paragraph of EN61326 here: "For I/O circuits where the manufacturer specifies that shielded cables must be used... the conducted immunity requirements can be omitted within the frequency range 150 KHz to 80 MHz." This is a convincing argument. Therefore EN61326 exempts 1000-4-6 from I/O ports with shielded cables. Thanks Eric.
