Overview of Allen-Bradley 1746-BAS-5/02 BASIC Language Module

The Allen-Bradley 1746-BAS-5/02 is a BASIC language module designed for the SLC 500 series programmable controllers. It enables custom serial communications, data handling, and control logic using the BASIC programming language. This module is ideal for tasks not easily performed with standard ladder logic, providing flexible control and data collection capabilities.

Key Features

  • Supports BASIC programming for flexible control logic and data manipulation
  • Dual serial ports: RS-232 and RS-422/423; compatible with ASCII and binary data
  • Allows custom protocols and serial device interfacing
  • Runs independently of the PLC scan cycle for continuous processing
  • Battery-backed RAM for program and data retention
  • Flash EEPROM for firmware updates
  • 24 KB RAM memory size, battery-backed
  • Communication ports support RS-232/423, RS-422, RS-485, and DH-485 protocols
  • Indicators: ACT (activity), 485, PRT1, PRT2, FAULT, BAT LOW, LED 1, LED 2 for diagnostics
  • Power supply loading: 150 mA at 5 V DC, 40 mA at 24 V DC
  • Operating temperature range: 0 to 60 °C (32 to 140 °F)
  • Designed for industrial noise immunity standards (NEMA)
