Overview

The Allen-Bradley 1746-BAS is a BASIC coprocessor module for the SLC 500 platform. It occupies one SLC 500 chassis slot and runs programs written in BASIC.

Memory and Programming

  • Program/data memory: 24 KB battery-backed RAM
  • Optional nonvolatile memory: 8 KB or 32 KB
  • Development software: 1747-PBASE
  • Programming: ASCII terminal or personal computer

Communications

The module has two configurable serial ports supporting RS-232/423, RS-422, and RS-485 communication with external devices.

Communication with an SLC 500 controller can use the 1746 backplane. DH-485 communication is available through the module's DH-485 port.

Memory Module Compatibility

The 1746-BAS supports 1747-M1 and 1747-M2 memory modules. Rockwell documentation also lists compatibility with the discontinued 1747-M3 and 1747-M4 modules.

Migration Note

Rockwell's SLC 500 hardware migration guide lists no direct Compact I/O replacement for the 1746-BAS. Existing systems may therefore require application-specific migration planning.

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.
