Application-Specific FAQ
Q: Can the SST-PFB-PLC5 operate as both a PROFIBUS master and slave simultaneously?
A: The module supports master or slave operation. Simultaneous master/slave on a single module is not supported; separate modules are required for multi-role topologies.
Q: What is the maximum cable length for a PROFIBUS-DP segment using this module?
A: At 12 Mbps, maximum segment length is 100 m. At 187.5 kbps, up to 1000 m. Use repeaters to extend beyond single-segment limits.
Q: Is this module compatible with RSLogix 5 programming software?
A: The SST-PFB-PLC5 is configured via SST’s own PROFIBUS configuration utility, not RSLogix 5 directly. Data exchange with the PLC-5 processor is via backplane block transfer or direct I/O mapping depending on firmware.
Q: Can I use this module in a ControlLogix or CompactLogix system?
A: No. This module is designed exclusively for the Allen-Bradley PLC-5 parallel backplane. For ControlLogix, specify the SST-PFB-CLX series instead.
Q: Do you provide GSD files and configuration software?
A: Yes. Contact [email protected] after purchase and we will provide the relevant GSD files and SST configuration software download link.
Q: What is the lead time for this part?
A: Typically 3–7 business days for in-stock units. Contact us for current availability and expedited shipping options.
