Product Description

Description

The Allen-Bradley 1746-BAS is a specialized BASIC module designed for the Allen-Bradley SLC 500 modular hardware platform. This intelligent co-processor module provides a high-level programming environment utilizing the BASIC language, enabling users to execute complex math calculations, handle string manipulation, and manage custom protocol communications. It acts as a powerful data collection node, foreign device interface, or operator interface controller within industrial automation systems.

Engineered to integrate seamlessly into standard SLC 500 chassis backplanes, the 1746-BAS features integrated program debugging tools, an extensive online help system, and flexible program and data storage options. Its robust operating parameters make it well-suited for machine-level control tasks that extend beyond standard ladder logic capabilities, bridging the gap between factory floor hardware and higher-level computer systems or serial peripheral devices.

Connections / Interfaces

The 1746-BAS module features front-accessible communication ports designed to interface with external serial devices, programming terminals, and link couplers. Physical connections typically utilize standard RS-232/422/485 wiring configurations depending on the deployed peripherals, allowing for flexible baud rate selection and protocol implementation through BASIC software routines.

Installation Guidelines

Always disconnect power to the SLC 500 chassis backplane before installing or removing the 1746-BAS module. Insert the module into any available I/O slot in the SLC 500 chassis, ensuring proper alignment with the backplane connector guide rails. Secure the module using the top and bottom retaining screws. Configure the module communication parameters and download the compiled BASIC program using the appropriate software development environment before placing the system into active operation.

FAQ

What is the primary function of the Allen-Bradley 1746-BAS module?

The Allen-Bradley 1746-BAS SLC 500 BASIC Module is an intelligent co-processor designed to provide a high-level BASIC programming environment for the SLC 500 platform. It enables users to execute complex math calculations, handle string manipulations, and manage custom protocol communications. This makes it an ideal solution for bridging factory floor hardware with foreign serial devices.

How does the Allen-Bradley 1746-BAS integrate into existing automation systems?

The Allen-Bradley 1746-BAS SLC 500 BASIC Module connects directly to standard SLC 500 chassis backplanes for seamless hardware integration. It draws 150 mA from the 5V DC backplane and features front-accessible communication ports for external serial peripherals. Proper installation requires securing the module with retaining screws and configuring communication parameters prior to operation.

What types of external equipment can connect to the Allen-Bradley 1746-BAS?

The Allen-Bradley 1746-BAS SLC 500 BASIC Module serves as a flexible interface for custom serial devices such as barcode readers, printers, and weigh scales. Its built-in serial communication capabilities allow for streamlined data collection, buffering, and protocol conversion. This empowers operators to manage terminal connections and legacy system modernization efficiently.

What are the power requirements for the Allen-Bradley 1746-BAS?

The Allen-Bradley 1746-BAS SLC 500 BASIC Module requires specific backplane current consumption values to operate correctly within an industrial chassis. It consumes 150 mA at 5V DC, while the 24V DC consumption is 70 mA for the module alone or 125 mA when utilizing a link coupler. Technicians must account for these electrical parameters during system design and power budget calculations.
