More Information

Overview Manuals Interfaces Network Configuration Application
  • PROFIBUS-DP Master Class 1 operation for Allen-Bradley PLC-5 systems
  • Automatic mapping of PROFIBUS I/O data into PLC-5 processor memory
  • Separate DP, RS-232 configuration, and 58-pin processor interfaces

SST-PFB-PLC5 is an SST PROFIBUS-DP coprocessor designed for the Allen-Bradley PLC-5 control platform.

Installed beside the PLC-5 processor in a 1771 chassis, it exchanges cyclic I/O with PROFIBUS-DP devices and makes that data available to the controller.

Before installation or replacement, verify processor compatibility, chassis power, connector alignment, PROFIBUS cabling and termination, memory mapping, and the retained SST configuration.

Availability, condition, price, and shipping time for SST-PFB-PLC5 are confirmed during quotation.

  • The PROFIBUS-DP interface uses a 9-pin female D-sub connector.
  • The configuration interface uses a 9-pin male RS-232 D-sub connector.
  • The coprocessor connects to the PLC-5 processor through a 58-pin header.
  • Use a linear shielded twisted-pair PROFIBUS segment terminated at both physical ends.
  • Supported DP rates extend from 9.6 kbit/s through 12 Mbit/s.
  • Segment length, drop length, repeater use, and station count depend on the selected data rate.
  • The SST configuration tool defines bus parameters, polling, communication relationships, and slave data.
  • Configuration data is transferred from a PC through the front RS-232 port.
  • Configured PROFIBUS input and output data is mapped into PLC-5 processor memory.
  • PLC-5 cyclic control of PROFIBUS-DP remote I/O stations
  • PLC-5 data exchange with PROFIBUS sensors, actuators, and distributed peripherals
  • PLC-5 integration with PROFIBUS gateways and operator-interface devices
Description
SST-PFB-PLC5 is an SST PROFIBUS-DP coprocessor for the Allen-Bradley PLC-5 platform.

The module operates as a DP Master Class 1, maps PROFIBUS I/O into PLC-5 memory, and provides separate PROFIBUS, RS-232 configuration, and processor interfaces.

Before installation or replacement, confirm the PLC-5 processor, 1771 chassis power capacity, 58-pin processor connection, PROFIBUS wiring and termination, network configuration, and saved project files.

Technical notes
SST SST-PFB-PLC5 mounts beside the PLC-5 processor and has no onboard bus termination; verify chassis power, DB9 wiring, external termination, and the saved DP configuration before replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Does SST SST-PFB-PLC5 fit in an ordinary 1771 I/O slot by itself?
No. SST SST-PFB-PLC5 attaches to the PLC-5 processor through its 58-pin interface, and the combined processor/coprocessor assembly is then installed in the 1771 chassis.
Why does SST SST-PFB-PLC5 need a separate RS-232 connection during setup?
The RS-232 port is the configuration path used to load bus parameters, communication relationships, object data, polling settings, and slave configuration into SST SST-PFB-PLC5.
Can SST SST-PFB-PLC5 terminate the PROFIBUS cable internally?
No. SST SST-PFB-PLC5 has no onboard network termination. Use approved PROFIBUS connectors or bus terminals with switchable termination at the two physical ends of the linear segment.
What should be checked before increasing the SST SST-PFB-PLC5 network baud rate?
Confirm cable type, total segment length, drop-cable length, connector quality, termination, repeaters, and every slave’s supported rate. Permitted line length decreases as baud rate increases.
Why can SST SST-PFB-PLC5 show a healthy PLC-5 connection but no field I/O updates?
The processor interface and PROFIBUS network are separate paths. Check DP configuration, slave addresses, GSD-derived parameters, memory mapping, bus wiring, termination, and the module’s status indicators.
Is a straight-through serial cable suitable for configuring SST SST-PFB-PLC5?
Do not assume so. The original procedure specifies the supplied null-modem serial cable between the PC and SST SST-PFB-PLC5; verify the required pinout before connection.
Can SST SST-PFB-PLC5 be ordered without checking the 1771 power budget?
No. SST SST-PFB-PLC5 requires 1.5 A at 5 V DC. Add this load to the processor and installed modules, then verify the chassis supply has adequate capacity.
