SST-PFB-CLX Profibus Scanner Communication Module

SST SST-PFB-CLX Profibus Scanner Module Configured for PROFIBUS DP network scanning and data exchange within ControlLogix platforms, the SST SST-PFB-CLX (SST-PFB-CLX Profibus Scanner Module) provides direct physical/electrical execution. Hardware Specifications Parameter Specification Model SST-PFB-CLX (SST-PB3-CLX) Brand SST / Molex / Honeywell Origin USA / Global Manufacturing Weight 2 kg Dimensions ControlLogix 1756 single-slot module format Operating Temp 0 deg C to 60 deg C Power Consumption 850 mA @ 5 VDC, 1.75 mA @ 24 VDC Product Type PROFIBUS DP Scanner / Communication Module Host Interface ControlLogix 1756 chassis backplane Communication Protocol PROFIBUS DP (DPV0 and DPV1) Maximum Slave Devices Up to 125 Transmission Baud Rates 9.6 kbps to 12 Mbps Physical Interface 9-pin D-sub connector (RS-485) Deterministic Network Communication and Backplane Integration The communication module manages cyclic input and output data exchanges across deterministic networks, supporting up to 125 PROFIBUS DP slave devices. Backplane bus communication velocities scale dynamically to accommodate large I/O density requirements, handling up to 1,984 bytes of input data and 1,968 bytes of output data. Integrated RS-485 physical drivers and protocol processing engines maintain telegram integrity and suppress bus arbitration latencies across distributed automation networks. Frequently Asked Questions Q: Can the SST-PFB-CLX module be inserted or extracted from an active ControlLogix chassis while powered? A: No. Power must be isolated from the specific 1756 chassis slot prior to module insertion or removal to prevent backplane bus corruption and electronic component damage. Q: How is the scanner module configured for network operation? A: Module configuration, bus parameters, and slave device mapping are established utilizing the SST PROFIBUS Configuration Tool via the onboard RS-232 serial port or backplane connection. Field Installation Guidelines Insert the module carefully into any available slot of a compatible ControlLogix 1756 chassis, ensuring proper alignment with the backplane connector. Secure the top and bottom retaining screws to lock the hardware firmly into the chassis frame. Terminate the PROFIBUS DP shielded twisted-pair cable to the 9-pin D-sub connector, maintaining proper shield grounding to suppress electromagnetic interference. Verify diagnostic status LED indicators upon system power-up to confirm valid master communication across the network segment.
