The PS69 PROFIBUS DP Master module expands the functionality of s CompactLogix / MicroLogix family of processors to include PROFIBUS. This module supports both I/O control and messaging, thus integrating DPV0 and DPV1 functionality into CompactLogix / MicroLogix. The PS69-DPM is a CompactLogix / MicroLogix compatible, PROFIBUS certified module, which enables controllers to communicate with a PROFIBUS network. The configuration and diagnostic of the PROFIBUS system is done via the serial diagnostic interface of the module using the System Configuration tool . The data exchange between controller and module is done via the I/O process data image using CompactLogix / MicroLogix backplane technology.
