More Information

Overview Manuals RS-232 Setup Bus Parameters Diagnostic Control Application
  • Configures a compatible PLC-5 PROFIBUS coprocessor through the Local Station Manager utility
  • Uses an RS-232 connection for bus parameters, diagnostics, events, and reset functions
  • Requires the separate coprocessor hardware, cable, software media, and saved station configuration

1785-PFB identifies the Allen-Bradley PLC-5 PROFIBUS Local Station Manager software.

The utility communicates with a compatible PLC-5 PROFIBUS coprocessor and provides configuration, status, event, and address-conversion functions.

Before service, preserve the installed software version, RS-232 setup, station addresses, bus parameters, event records, and identity of the separate coprocessor hardware.

Availability, condition, price, and shipping time for 1785-PFB are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • The official setup connects a computer to the coprocessor through RS-232.
  • The rear connector uses documented transmit, receive, and data-ground pins.
  • The selected computer communication port must match the physical cable.
  • Local Station Manager provides access to the documented PROFIBUS parameters.
  • Address-conversion and switch information can be reviewed through the utility.
  • Save the installed bus configuration before hardware or software changes.
  • The utility reports module state, communication versions, and system events.
  • No Communication status directs the user to connection and port-setting checks.
  • Reset functions should be used only after the active configuration is preserved.
  • PLC-5 PROFIBUS systems administered through the Local Station Manager utility.
  • Configuration recovery involving RS-232 access, saved bus parameters, and station addresses.
  • Diagnostic work using module state, event, switch, and communication-version information.
Description
Allen-Bradley 1785-PFB is the PLC-5 PROFIBUS Local Station Manager software package documented for use with a compatible PLC-5 PROFIBUS coprocessor.

The official guide covers RS-232 connection, communication-port selection, bus-parameter setup, event monitoring, address conversion, reset functions, battery checks, and module information.

Ordering should distinguish the 1785-PFB software from the separate coprocessor hardware and should confirm the required software media, host-computer environment, RS-232 cable, and saved PROFIBUS configuration.

Technical notes
1785-PFB is the PLC-5 PROFIBUS Local Station Manager software, not the coprocessor hardware; confirm the separate coprocessor catalog, software media and version, RS-232 cable, host-computer compatibility, and saved bus parameters.

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.
What should be included when ordering Allen-Bradley 1785-PFB?
Confirm the Local Station Manager software media and version, host-computer compatibility, documentation, and the RS-232 cable required for the separately identified PLC-5 PROFIBUS coprocessor.
How is Allen-Bradley 1785-PFB configured according to the official guide?
A computer connects to the PROFIBUS coprocessor over RS-232 and uses the PLC-5 PROFIBUS Local Station Manager utility.
What configuration should be saved before replacing Allen-Bradley 1785-PFB?
Retain bus parameters, station addresses, address conversions, communication-port settings, module and software versions, event information, and the PLC-5 application context.
Why might Local Station Manager show no communication with Allen-Bradley 1785-PFB?
Inspect the RS-232 cable pinout, selected computer port, module power and state, switch settings, connector seating, and utility communication setup.
Does Allen-Bradley 1785-PFB include the PLC-5 PROFIBUS coprocessor hardware?
No. The official publication identifies 1785-PFB as the Local Station Manager software. Verify the separate coprocessor catalog, cabling, and saved bus configuration.
What should be checked before resetting Allen-Bradley 1785-PFB communication?
Preserve the active bus configuration and event information, confirm the affected process is safe, and follow the official Local Station Manager reset procedure.
Can Allen-Bradley 1785-PFB be recommissioned when the original Local Station Manager configuration is unavailable?
The bus setup may be reconstructed only through a controlled engineering process using verified station addresses, parameters, connected devices, and PLC-5 behavior; obtaining the original configuration remains the safer approach.
