Operating within the ControlLogix chassis, the module provides direct I\/O image mapping and paged memory access up to 250 status words to balance backplane bus communication velocity with maximum payload throughput. Onboard diagnostic assets, including a 4-character scrolling display and dedicated COMM, SYS, and OK status LEDs, deliver real-time operational feedback without requiring external programming tools.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the SST-PB3-CLX support simultaneous PROFIBUS Master and Slave operation on the network?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The module firmware supports both PROFIBUS DP-V0 and DP-V1 protocol stacks in Master or Slave modes, enabling master data collection and slave status reporting over a single RS-485 bus line.\u003c\/p\u003e\n\u003cp\u003eQ: What power draw does the SST-PB3-CLX place on the ControlLogix backplane?\u003c\/p\u003e\n\u003cp\u003eA: The module draws 850 mA from the 5 VDC backplane rail or 1.75 mA from the 24 VDC rail depending on chassis power supply distribution configuration.\u003c\/p\u003e\n\u003cp\u003eQ: How is the PROFIBUS bus baud rate configured on the SST-PB3-CLX interface?\u003c\/p\u003e\n\u003cp\u003eA: The onboard network interface features auto-detection capability across standard PROFIBUS communication speeds from 9.6 kbps up to 12 Mbps, matching master node configuration automatically upon bus initialization.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInsert the SST-PB3-CLX module into any available slot in a ControlLogix 1756 backplane until the top and bottom chassis levers click into place.\u003c\/li\u003e\n\u003cli\u003eConnect a shielded PROFIBUS RS-485 cable equipped with a standard 9-pin D-sub male connector to the module front interface.\u003c\/li\u003e\n\u003cli\u003eVerify that bus termination resistors are switched ON at both physical endpoints of the PROFIBUS RS-485 line.\u003c\/li\u003e\n\u003cli\u003eRoute PROFIBUS network cabling in dedicated grounded conduits separated from high-voltage AC power conductors.\u003c\/li\u003e\n\u003cli\u003eApply power to the ControlLogix rack and verify that the front panel OK LED shows solid green signaling backplane initialization.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48749917601982,"sku":"SST-PB3-CLX","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-08-18_09-33-29_1495f5cb-0811-47ee-a4ae-a6b4d92fff93.png?v=1787018206","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-sst-pb3-clx-communication-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
