Abstract: A redundantly operable communication system for an industrial automation system, wherein a first communication device is redundantly connected to a third communication network connection of first and second network infrastructure devices, the second communication device is redundantly connected to a third communication network connection of a third and fourth network infrastructure device, where the first and third network infrastructure device and the second and fourth network infrastructure devices are interconnected via their first and second communication network connections such that, while the first and second communication device identify data frames to be redundantly transmitted via a first indicator, the first and third network infrastructure devices and the second and fourth network infrastructure devices identify data frames to be redundantly transmitted via a second or third indicator that differs from the first indicator, and reject data frames received on the third communication connection and i

Abstract: The invention relates to an absorbent, disposable article, preferably a diaper, having a backsheet and a topsheet comprising a first waist region, a second waist region, and a crotch region interposed there between, a longitudinal axis, and an opening, which provides a passageway to a primary void space for receiving bodily exudates therein, positioned between the topsheet and the backsheet; whereby the opening is positioned in at least the crotch region along the longitudinal axis; whereby the topsheet is elasticated; and whereby the article has a shortened article portion, as defined herein, which has a shortened article length L, a stretched shortened article length Ls and a contacted shortened article length Lc, whereby the article and/or its topsheet has an specific elastic profile and/or a specific ratio of Lc to Ls.
