Description

The Allen-Bradley 1746-BAS-T is a high-speed BASIC module designed for the SLC 500 platform. It functions as an independent co-processor, enabling the execution of complex calculations, string manipulation, and custom communication protocols without impacting the main PLC processor's scan time. The '-T' designation signifies an enhanced clock speed compared to the standard 1746-BAS, providing superior performance for high-throughput data collection and interfacing with external devices such as HMIs, barcode scanners, and modems.

Features

High-speed processing for advanced data handling and custom BASIC programming.
Three integrated communication ports for versatile connectivity.
Supports RS-232, RS-422, and RS-485 electrical standards on PRT1 and PRT2.
Dedicated DH-485 port (PRT3) for network integration and daisy-chain configurations.
24 KB of battery-backed RAM for program and data storage.
Efficient co-processor architecture to reduce main CPU load.

Applications

This module is widely used in industrial automation for custom protocol emulation, complex data processing, and interfacing legacy or third-party serial devices into an SLC 500 control system. It is ideal for applications requiring rapid data throughput that exceeds the capabilities of standard communication modules.

Installation Guidelines

Ensure the SLC 500 chassis power is disconnected before installing or removing the module.
The module must be seated firmly in the chassis slot to ensure proper backplane connection.
Use shielded communication cables for all serial connections to minimize EMI interference.
Ensure proper grounding of the chassis to a common earth ground to prevent electrical noise.
Handle the module using ESD-safe practices to prevent damage to internal circuitry.
Verify that the battery is properly installed and connected to maintain memory during power cycles.

FAQ

What is the primary difference between the 1746-BAS and the 1746-BAS-T?

The 1746-BAS-T is a high-speed version of the standard BASIC module, featuring a faster clock speed for improved processing performance in demanding data-intensive applications.

Can I use this module to communicate with third-party serial devices?

Yes, PRT1 and PRT2 support RS-232, RS-422, and RS-485 standards, allowing you to write custom BASIC programs to interface with a wide range of third-party serial hardware.
