1747-BSN Allen-Bradley Backup Scanner Module Rockwell Automation


Description of 1747-BSN

The Allen-Bradley 1747-BSN is a backup scanner module. The 1747-BSN backup scanner is available with redundancy for remote I/O (RIO). The 1747-BSN is equipped with RS-232 channel switching for communication with devices such as operator interfaces. This module also has a DH+ link. This module is a set of complementary modules, with one module located in the main system and other modules in the secondary or backup system. The main module controls all the remote I/O operations. The secondary module is available to take over the control if something goes wrong on the primary module. The backup scanner has the ability to switch between 2 communication channels. The first channel can be configured as RIO or DH +. The second channel is used to replace the RS-232/485 channels to provide connections for the operator's electronic interface. DH+/RIO and RS-232/485 channels can be used together.

The Allen-Bradley 1747-BSN provides a High-Speed Serial Link (HSSL) for writing retentive data from the primary processor to secondary processor. In addition, this module has a Local Serial Link (LSL) to convey status information between several 1747-BSN modules residing on the same chassis. The 1747-BSN has a backplane current consumption of 800 mA at 5V. The Allen-Bradley 1747-BSN’s operating temperature is 32-140 °F and its storage temperature is -40-185 °F. The relative humidity is from 5-95%, noncondensing. Please remember to make sure that you have set the DIP switch correctly before installing the scanner.


About 1747-BSN Ser A

The 1747-BSN Series A module is an Allen-Bradley SLC 500 backup scanner module featuring a backplane current of 800 milliamps at 5 Volts DC while the cable type used on the unit is the Belden 9463 cable. The 1747-BSN Series A module is compatible with the SLC 5/02, 5/03, 5/04, and 5/05 processors. The unit features a 6-pin Phoenix connector and comes with a high-speed communication channel between the 2 modular SLC 500 processors. The 1747-BSN Series A module comes with a backup system that uses a set of modules and comes with 1 or more modules that resides in the primary system. The 1747-BSN Series A module also comes with 1 or more complementary modules that are in the secondary or backup system. The primary system is responsible for controlling the operations of the remote I/O while the secondary system is responsible for monitoring the communications of the module by using the high-speed serial link.

The Allen-Bradley 1747-BSN Series A module features the ability to switch from 1 communication channel to another, ensuring a continuous flow of information. The initial channel is configurable as the remote I/O channel or the Data Highway Plus (DH+) channel. The second channel is 1 that is used for switching 1 RS232/485 channel so as to provide a connection for the electronic operator interfaces. During the transfer of control from a particular processor to another, the output modules in the remote chassis of the 1747-BSN Series A module is set to maintain the unit’s last state until the secondary processor program takes control.
