Allen Bradley 1747-BSN module belongs to the category of SLC 500 backup scanner modules. It is equipped with redundancy for remote I / O (RIO). This module has the ability to change channels to simplify communication with devices, including operator interfaces. It includes a DH + link, which allows the first channel of this unit to be configured as RIO or DH +. The second channel can take control of the RS-232/485 and replace it, to maintain a continuous connection to the electronic operator interface. These two channels (DH + or RIO and RS-232/485) can also be used next to each other.
