1747-PIC Allen Bradley

Description

Product Name: 1747-PIC  Allen Bradley Processor module

Product details:

The Allen-Bradley 1747-PIC (Personal Computer Interface Converter) is a communication module designed to facilitate programming and communication between a personal computer and Allen-Bradley SLC 500 programmable logic controllers. It converts RS-232 signals from a computer’s serial port (COM port) to RS-485 signals used by the DH-485 (Data Highway 485) network, which is common in SLC 500 systems. This enables users to connect to the SLC 500 processor using software like RSLogix 500 and RSLinx for tasks such as program upload/download, online monitoring, and troubleshooting.

Product Parameters

While specific, detailed parameters can vary slightly based on the exact revision, here are typical specifications for the 1747-PIC:

• Manufacturer: Rockwell Automation / Allen-Bradley
• Series: SLC 500
• Module Type: RS-232 to DH-485 Interface Converter
• Interface Type: Coaxial (DH-485 side), RS-232 serial (PC side, typically DB9 or DB25)
• Power Supply: Typically draws power from the connected device or an external source (e.g., 24V DC). It draws a maximum current of 0A at 5V and 5A at 24V. Max wattage is 2 Watts.
• Compatibility: Compatible with COM1 and COM2 serial ports on a PC. Connects to SLC 500 processors via the DH-485 communication port.
• Communication Cable: Requires specific cables like the 1746-C10 for connection to the SLC controller. Belden #3106 or #9842 for DH485 communication.
• Operating Temperature: 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit)
• Storage Temperature: -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit)
• Humidity: 5 to 95% non-condensing
• Dimensions (Approximate): Varies, but generally compact (e.g., around 8 x 8 x 8 inches or 13cm x 10cm x 20cm).
• Weight (Approximate): Around 0.29 kg (0.64 lbs) to 2.4 lbs shipping weight.

Product Advantages

• Enables PC-to-PLC Communication: The primary advantage is its ability to establish a communication link between a standard PC (with an RS-232 serial port) and SLC 500 PLCs, which use the DH-485 protocol. This is crucial for programming and diagnostics.
• Reliability: As an Allen-Bradley product, it is built with robust design principles for industrial environments, offering dependable performance and stable communication.
• Legacy System Support: It provides essential connectivity for maintaining and working with existing SLC 500 installations, which are still widely used in many industrial applications.
• Direct Connectivity: It offers a direct and relatively simple method for connecting to the PLC without requiring more complex network configurations for basic programming tasks.

Precautions

• Driver Compatibility: Ensure the correct drivers are installed on your PC for the 1747-PIC to function properly.
• Power Management: Turn off power management functions on the PC’s COM port, as these can inhibit the PIC driver’s functionality.
• Cable Type: Use the correct communication cables (e.g., 1746-C10) for connecting the 1747-PIC to the SLC 500 controller.
• Grounding and Wiring: Adhere to proper grounding requirements and wiring guidelines as specified by Allen-Bradley (refer to publication 1770-4.1, “Industrial Automation Grounding and Wiring Guidelines”) and local electrical codes.
• Communication Protocol Settings: When using the DH-485 for communication, ensure the DH-485 is set as the program port in the PLC’s configuration and terminal selection menus. DF1 protocol can be used for communication with external devices via other links.
• Operating Environment: Ensure the operating environment falls within the specified temperature and humidity ranges to prevent damage or malfunction.
• Firmware: Be aware that obtaining and installing firmware updates for older equipment like the 1747-PIC might be challenging from official sources.
• Windows XP SP3 Issue: Some users have reported issues with the 1747-PIC and Windows XP Service Pack 3 breaking the RS232 driver. Using an older Windows XP SP2 or earlier, or considering a 1747-UIC (USB to DH-485) as an alternative, might be necessary.
• Null Modem: Ensure proper null modem wiring if using an adapter, as RX/TX assignments can differ between DB9 and DB25 connectors.

Product Applications

The Allen-Bradley 1747-PIC is primarily applied in industrial automation settings where SLC 500 PLCs are in use. Its main applications include:

• PLC Programming: Connecting a personal computer running RSLogix 500 software to an SLC 500 processor for developing, editing, uploading, and downloading PLC programs.
• System Diagnostics and Troubleshooting: Monitoring PLC status, I/O, and data tables in real-time to diagnose issues and troubleshoot industrial processes.
• Online Monitoring: Observing the live operation of the PLC and connected devices for performance analysis and process optimization.
• Data Exchange: Facilitating data exchange between the PLC and other systems or HMI (Human Machine Interface) devices that communicate via the DH-485 network.
• Maintenance and Servicing: Essential for routine maintenance, program modifications, and firmware updates (if applicable) for SLC 500 controllers.
