BASIC Communication Module

This single-slot module is a powerful solution that allows the large installed base of legacy BASIC programs for the 1771-DB and 1747-BAS modules to be migrated to the ControlLogix platform with minimal effort.

Features and Benefits

The MVI56-BAS module allows you to

  • Create BASIC programs to transfer data between the ControlLogix and the MVI56-BAS module
  • Create foreign device interface for specific applications and easily integrate the device with the ControlLogix processor
  • Interface to many devices that use ASCII interface to a ControlLogix backplane such as modems, printers, bar code readers, and scales
  • Save ControlLogix processor memory by running math algorithms
  • The module acts as DF1 full-duplex device or a DF1 half-duplex slave

The BASIC programs are stored in the MVI56-BAS Compact Flash disk allowing the user to easily backup the BASIC programs to another Compact Flash disk or to a local PC. Up to 24065 Bytes of RAM are available.

The module contains three ports:

  • DH-485: DH-485 communication or BASIC program transfer
  • PRT1: ASCII communication or program port
  • PRT2: ASCII communication or DF1 communication

The user can either create the BASIC programs using the command line, then save it to Compact Flash, or create the program on a PC and download it to the MVI56-BAS module. The user can also configure the module to execute a BASIC program automatically at power up.

Applications

The MVI56-BAS module allows existing legacy BASIC programs to be migrated from the 1771 and 1746 platforms to the ControlLogix platform. This provides interface capability for many devices using the ASCII interface to the ControlLogix backplane including:

  • Bar code scanner interfaces
  • Weigh scale interfaces
  • Legacy ASCII protocol connections
  • Terminal port emulation
  • Printer driver (alarm/status printer)

Specifications

  •  Single Slot – 1756 backplane compatible
