Molex Inc. presents the SST IP67 PB3 Remote Module that is designed to provide a fast and easy solution for adding PROFIBUS master and slave connectivity to Rockwell Logix controllers in factory automation, process control and complex machine applications.

The linking device has on-board PROFIBUS and Ethernet communication ports and can be installed directly on the machine or in the field to reduce the requirement of costly PROFIBUS cabling required to connect the controller and field device. It executes high speed PROFIBUS-DP data exchange with the Logix controller with up to 2KB input + 2KB output PROFIBUS process data. It is fully integrated into the Rockwell Software Architecture through features such as add-on instructions, access to PROFIBUS DP-V1 services and diagnostics and direct access from RSLogix 5000 to PROFIBUS I/O data, without writing any ladder logic.

Other features of the communication module include an engineering software console for automatic DP device discovery, configuration and diagnostics; AOI export of PROFIBUS I/O variables in RSLogix 5000 (.L5X) format, so users can browse PROFIBUS tags (with correct name, type, etc.); the ability to simultaneously run PROFIBUS master and slave protocols; and a CommDTM driver that allows Rockwell users in process control industries to perform asset management with software, such as FactoryTalk AssetCentre, PACTware and FieldCare.

The module is also available in a conformal coating version that extends the working life and improves security and reliability of performance in extreme or humid conditions.
