MVI56-BAS
Prosoft Basic Communications Module for ControlLogix

The Prosoft MVI56-BAS is a single-slot module that enables 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.
