The SST-PB3-CLX is a high-performance PROFIBUS DP master/slave communication module from Molex, designed specifically for Rockwell Automation ControlLogix systems.
Supports up to 15 listen-only connections plus 1 output connection
The SST-PB3-CLX-RLL is the PROFIBUS scanner for the 1756 (ControlLogix) backplane and Honeywell PlantScape system. It enables communication between a CLX processor and DP remote I/O devices on a PROFIBUS network, acting as a PROFIBUS DP remote I/O scanner.Use the SST PROFIBUS Configuration Tool to configure the scanner. You can have up to 4 pages of 248 words of input data and 4 pages of 246 words of output data. The Tool also allows you to configure I/O on the DP network, enabling you to download the configuration to the scanner via the serial port or an RSLinx driver. The scanner stores this configuration in its flash memory, so you don't need to download it every time you start the CLX. The input and output data for the slaves is mapped into the ControlLogix 5550 Controller’s I/O Data arrays, starting at byte offset 4. The mapping depends on the addresses you assign in your Master configuration.

When deploying the SST-PB3-CLX module in a ControlLogix chassis, engineers must ensure the PROFIBUS network configuration is properly downloaded and verified via the SST PROFIBUS Configuration Tool and stored in the onboard flash memory to prevent data loss upon system reboots . It is critical to precisely manage the 4-page data array mapping in the PLC registers, keeping in mind that the slaves' I/O data arrays start strictly at byte offset 4 inside the ControlLogix controller. Technicians should double-check the maximum rack density, as no more than 8 scanners should reside in a single chassis to avoid backplane power overload. Lastly, prior to executing any Removal and Insertion Under Power operations, the PROFIBUS master scan must be safely inhibited to avoid fieldbus telemetry disturbance and unpredictable slave states.
It is a PROFIBUS scanner module designed to enable communication between a control system and PROFIBUS DP field devices as a master or slave.
Which PROFIBUS standards does the SST-PB3-CLX support?
It supports PROFIBUS DP-V0 and DP-V1 for cyclic and acyclic data communication.
What are the data mapping capabilities of the SST-PB3-CLX per slave?
It supports and scans up to 122 words of input data and 122 words of output data per slave, mapping them into the ControlLogix controller’s I/O data arrays.p to 12 Mbps.
Where does the SST-PB3-CLX store its network configuration?
The module stores the downloaded configuration in its onboard non-volatile flash memory, eliminating the need to re-download the network setup every time the CLX chassis restarts.
