The Allen-Bradley SST-PFB-SLC is a high-performance PROFIBUS DP Master/Slave scanner module designed for the Allen-Bradley SLC 500 platform. This module enables SLC 5/02, 5/03, 5/04, and 5/05 processors to seamlessly connect to a PROFIBUS DP network, facilitating robust and high-speed communication with a wide range of field devices such as drives, remote I/O, and other controllers. It functions as both a master and a slave, offering flexible network architecture and easy integration into existing industrial automation systems. The module is configured using dedicated software, allowing for straightforward setup of network parameters and data exchange between the PLC and PROFIBUS devices.
