Bringing Profibus connectivity to the Rockwell Contrologix platform

07 January 2011

Molex has released the Brad SST PB3 remote module for Profibus, a stand-alone hardware platform including Profibus and Ethernet communication ports, enabling fast and easy connectivity to any Rockwell ControlLogix and CompactLogix controller. The PB3 module can be installed close to the Profibus field device, reducing cabling costs.

The PB3 Remote Module fits factory automation, process control and machine building applications. It is fully integrated into the Rockwell software architecture through features such as ‘Add-on-Instructions’, which saves integration time; Ethernet switch with redundancy capability (DLR); direct access to I/O data without the need to write ladder logic and complete access to Profibus DP-V1 services and device diagnostics.

Additional features include:
· Engineering console that runs Profibus master and slave protocols simultaneously
· Remote configuration and diagnostics via an Ethernet connection for quick commissioning
· CommDTM driver, which allows Rockwell users in process control industries such as oil/gas and food/beverage to perform asset management
· Easy sharing of I/O process data and the ability for multiple types of equipment to connect to a single PB3 remote module
