Description

The Allen-Bradley 1746-BAS is a specialized co-processor module designed for the SLC 500 programmable controller system. It enables the execution of independent BASIC programs, allowing for advanced data processing, complex string manipulation, and custom communication protocols that standard I/O modules cannot handle. This module acts as an intelligent bridge between the PLC and various serial-based peripheral devices.

Features

Executes independent BASIC programs for custom data manipulation and logic.
Equipped with 24 KB of battery-backed RAM for program and data storage.
Three configurable communication ports for versatile device interfacing.
Supports RS-232, RS-422, and RS-485 electrical standards.
Integrated DH-485 network port for system-wide communication.
Configurable DF1 protocol support on PRT2 for modem and serial connectivity.

Applications

The 1746-BAS is commonly utilized in industrial environments requiring integration with non-Allen-Bradley hardware. Typical applications include interfacing with bar code scanners, industrial printers, modems, weigh scales, and custom serial instrumentation that requires specific data formatting or protocol translation.

Installation Guidelines

Ensure the SLC 500 chassis power is disconnected before installing or removing the module.
Seat the module firmly into the designated SLC 500 chassis slot and secure it using the integrated mounting screws.
Use shielded communication cables to minimize electromagnetic interference (EMI) in industrial environments.
Maintain proper ventilation within the enclosure to ensure the module operates within the 0 to 60 degC temperature range.
Follow standard ESD precautions when handling the module to prevent damage to internal circuitry.
Note: Enabling the DF1 protocol on PRT2 will disable the DH-485 network port (PRT3).

FAQ

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

The 1746-BAS serves as a co-processor that runs BASIC programs to handle tasks like custom serial communication, string processing, and data collection, offloading these tasks from the main SLC 500 processor.

Can the 1746-BAS communicate with non-AB devices?

Yes, the module is specifically designed to interface with third-party serial devices such as bar code scanners, printers, and weigh scales using its configurable RS-232/422/485 ports.

What happens if I enable DF1 on PRT2?

Enabling the DF1 protocol on the second serial port (PRT2) will automatically disable the DH-485 network port (PRT3), as they share internal resources.
