4. Product Introduction (Anti-Template)
The SST-PB3-CLX is a PROFIBUS communication module designed for the Allen-Bradley ControlLogix (1756) platform. Manufactured by SST/Woodhead (later Molex), it installs in a ControlLogix chassis and enables the Logix controller to exchange data with PROFIBUS DP devices.
The module supports both Master and Slave operation under PROFIBUS DP-V0 and DP-V1, with baud rates from 9.6 kbps to 12 Mbps. It provides substantial I/O data capacity (approximately 1984 bytes of input and 1968 bytes of output) and connects to the PROFIBUS network via a standard 9-pin D-sub connector. Configuration is performed with the SST PROFIBUS Configuration Tool and/or the corresponding Add-on Profile in Studio 5000 / RSLogix 5000. The module is commonly used when ControlLogix systems must integrate existing PROFIBUS remote I/O, drives, or third-party devices. Exact firmware revision and configuration files must be matched when replacing an existing unit.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full model number (SST-PB3-CLX), revision level, connector condition, and LED/display integrity. Photograph all labels.
- Functional Testing – Install in a compatible ControlLogix chassis, apply power, and verify module status LEDs and basic backplane recognition. Full validation requires PROFIBUS network connection and configuration download.
- QA & Packaging – Protect the D-sub connector and backplane edge connector, clean according to electronics handling practices, and pack in anti-static protective packaging.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial communication modules. Packaging must protect against electrostatic discharge; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
GSD and Configuration Files – Use the correct GSD files and SST configuration project. Mismatched configuration will prevent proper slave communication.
Master/Slave Mode – Confirm whether the application requires Master, Slave, or simultaneous operation and set the module accordingly.
Backplane Power – Ensure the ControlLogix power supply can support the module’s 5 V current draw along with other modules in the chassis.
Firmware and AOP Compatibility – Match the module firmware and Add-on Profile version to the Studio 5000 / RSLogix 5000 revision in use.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified SST-PB3-CLX?
As a specialized ControlLogix PROFIBUS module, availability depends on surplus stock. Typical lead time after verification is 5–15 business days plus standard shipping.
What is the primary function of this module?
It is a PROFIBUS DP scanner that allows a ControlLogix controller to communicate with PROFIBUS devices as Master and/or Slave.
What PROFIBUS versions does it support?
PROFIBUS DP-V0 and DP-V1.
What is the maximum baud rate?
12 Mbps.
How is the module configured?
Using the SST PROFIBUS Configuration Tool and/or the Add-on Profile in Studio 5000 / RSLogix 5000.
Is the module still in production?
The SST-PB3-CLX is a mature/legacy product. Availability is primarily through surplus and specialist channels.
What should be confirmed before ordering a replacement?
Exact model (SST-PB3-CLX), required firmware revision, existing configuration/project files, and compatibility with the ControlLogix chassis and Studio 5000 version.
