The SST-PFB-PLC5 is a dedicated Profibus DP co-processor module built for Allen‑Bradley PLC‑5 controllers. It enables seamless integration of PLC‑5 systems into industrial Profibus DP networks, acting as a Class 1 DP Master to control and exchange real‑time I/O data with multi‑vendor slave devices. It also supports DP Slave operation for integration into multi‑master architectures. This module is a direct, high‑performance alternative to the Allen‑Bradley 1785‑PFB/B, designed for 1771 I/O chassis environments.

Mounting |
1771 rack-mount module |
The SST-PFB-PLC5 is a robust, industrial‑grade communication co-processor that mounts directly adjacent to the PLC‑5 CPU in a 1771 chassis. It features three front‑panel LEDs for real‑time status monitoring:
OK: Power and module health
SYS: Bus protocol and slave status
COM: Data transmission and bus error status
The module auto‑maps I/O and diagnostic data to PLC‑5 integer (N) files without ladder logic programming for cyclic data exchange. Configuration is done via a PC using SST Profibus software and RS‑232, with settings stored in flash memory for power‑off retention. It supports both Master and Slave modes simultaneously for flexible network design.
Connecting Allen‑Bradley PLC‑5 systems to Profibus DP networks
Integrating third‑party Profibus slaves (drives, valves, sensors, HMIs) with PLC‑5
Connecting distributed I/O (e.g., Siemens ET200 series) to PLC‑5
Multi‑master industrial network architectures
Legacy PLC‑5 system modernization and fieldbus upgrade
Factory automation, process control, and material handling systems
Multi‑vendor device communication in automotive, packaging, and manufacturing
Dual Mode Operation: Profibus DP Master + DP Slave in one module
Plug‑and‑Play Installation: Direct 1771 chassis mounting with PLC‑5
Auto Data Mapping: I/O and status mapped to PLC‑5 N files automatically
Full Baud Rate Support: 9.6 kbps to 12 Mbps for wide network compatibility
Flash Memory Storage: Saves configuration through power cycles
Advanced Diagnostics: Real‑time bus status, slave health, and error reporting
Firmware Upgradable: Field‑updatable via RS‑232
High‑Speed Performance: Data cycle faster than typical PLC scan times
Industrial Rugged Design: EMC‑certified, noise‑immune for factory environments
1785‑PFB/B Compatible: Direct replacement with improved functionality
1. Is ladder logic required for data exchange?
No. The SST-PFB-PLC5 handles cyclic I/O data exchange automatically. Only PLC‑5 integer (N) file setup is needed.
2. How many Profibus slaves can it support?
Up to 32 slaves per segment; up to 126 slaves with repeaters.
3. Where is I/O data stored in the PLC‑5?
Data is mapped to integer (N) data files: dedicated files for input, output, and status.
4. What do the SYS LED colors mean?
Green: All slaves healthy; PLC in RUN mode
Amber: Slaves online; PLC in PROG/TEST mode
Red: Slave fault, configuration error, or bus failure
5. Can the module run as a DP Slave only?
Yes. You can configure it as a standalone DP Slave using serial terminal commands.
6. How do I download the configuration file?
Use a terminal program (HyperTerminal) with Xmodem to send .bss configuration files via RS‑232.
7. Is this a replacement for 1785‑PFB/B?
Yes. The SST-PFB-PLC5 is a fully compatible, higher‑performance alternative.
8. What causes PLC‑5 faults 95 or 102–105?
Fault 95: Module hardware or critical configuration error
Faults 102–105: Missing or undersized PLC‑5 integer data files
