PRODUCT DESCRIPTION
Allen-Bradley 1747-PIC Overview
The Allen-Bradley 1747-PIC (Personal Computer Interface) is an interface converter that facilitates communication between a personal computer and Allen-Bradley SLC 500 PLCs and other devices on a DH-485 network. It allows users to program, monitor, and troubleshoot SLC 500 controllers from a PC using software like RSLogix 500.
Product Detailed Description
Function: The 1747-PIC converts RS-232 serial communication signals from a PC to the DH-485 (Data Highway 485) protocol used by Allen-Bradley SLC 500 controllers and other compatible devices. This enabled older PCs, which typically had RS-232 ports, to connect to and interact with the DH-485 network.
Purpose: It served as a vital link for programming, uploading/downloading programs, online monitoring, and troubleshooting SLC 500 PLC systems.
Design: It typically features a 25-pin D-sub connector for the RS-232 side (connecting to the PC) and a coaxial interface for the DH-485 side (connecting to the PLC network).
Legacy Device: It's important to reiterate that this is a legacy product, discontinued by Rockwell Automation. Its functionality is now often handled by USB to DH-485 converters (like the 1747-UIC) for modern computers.
Product Parameters
While specific detailed parameters can vary slightly by series (e.g., Series A), common characteristics include:
Interface Type (PC Side): RS-232 (25-pin D-sub connector)
Interface Type (PLC Side): DH-485 (Coaxial connector)
Maximum Supply Voltage: Typically around 24 Volts (often powered by the PLC or an external source)
Communication Protocol: DH-485
Compatibility: Primarily designed for Allen-Bradley SLC 500 series PLCs (SLC 5/01, 5/02, 5/03, 5/04, 5/05) and other DH-485 compatible devices like PanelView terminals.
Dimensions: Approximately 13cm x 10cm x 20cm (varies slightly)
Weight: Approximately 0.29 kg (varies slightly)
Operating Temperature: 0°C to +60°C (+32°F to +140°F)
Storage Temperature: -40°C to +85°C (-40°F to +185°F)

Product Advantages
Essential Communication Link (Historically): At its time, it was essential for connecting PCs to the widely used DH-485 network, enabling programming and diagnostics of SLC 500 systems.
Reliable for Legacy Systems: For existing legacy systems still utilizing SLC 500 PLCs, the 1747-PIC (or its USB successor) remains a necessary tool for maintenance and modifications.
Direct Connection: Provided a direct and dedicated communication path.
Precautions
Discontinued Product: As a discontinued product, availability may be limited to surplus markets, and manufacturer support is no longer provided.
Driver Compatibility: Requires specific drivers (often bundled with older RSLinx software versions) to function correctly with the operating system of the personal computer. Newer operating systems might have compatibility issues or require specific driver installations/updates.
RS-232 Port Requirement: Modern laptops and many desktop computers no longer include native RS-232 serial ports, necessitating the use of USB-to-serial adapters, which can introduce their own set of compatibility challenges.
Proper Cabling: Correct RS-232 and DH-485 cabling is crucial for proper communication.
Power Supply: Ensure the 1747-PIC receives proper power, either from the PLC or an external source, as required by the specific model.
Product Applications
PLC Programming and Configuration: The primary application was to connect a PC running Rockwell Automation's RSLogix 500 programming software to SLC 500 PLCs for program development, download, and upload.
Online Monitoring and Diagnostics: Allowed technicians to monitor PLC status, I/O, and data tables in real-time for troubleshooting and process optimization.
HMI Communication: Facilitated communication between older PanelView terminals and SLC 500 controllers via the DH-485 network.
Data Acquisition: Enabled data exchange between SLC 500 PLCs and SCADA systems or other data acquisition software.
System Upgrades and Maintenance: Still used for maintaining and, if necessary, upgrading existing SLC 500 based control systems.
