Module Overview and Functional Positioning
The SST-PB3-CLX-RLL is a PROFIBUS scanner module developed by Molex, primarily serving as a communication interface between the ControlLogix (CLX) system and PROFIBUS networks. As a PROFIBUS DP master, it supports data interaction with remote I/O devices and integrates advanced DPV1 communication capabilities to enable complex industrial automation control scenarios. The module features hot-swappable design and built-in diagnostics for real-time monitoring of network status and device operation, making it suitable for industrial control systems requiring high reliability and flexibility.
