Description

Prosoft PLC Communication Module MVI94-ADM

• Extended Product Type : ASCII

• Product ID: MVI94-ADM

• Prosoft Type Designation : ASCII

Features and Benefits

Powerful platform for developing and running ‘C’ applications on Rockwell Automation’s FLEX I/O processors. The MVI94-ADM module is a single slot, backplane compatible solution for the Rockwell Automation FLEX I/O and Integra I/O platforms. This module is a powerful and programmable solution supporting two fully isolated serial ports allowing serial field devices to be integrated into the FLEX platforms.

The MVI94-ADM module has two serial ports, both of which are isolated for field interfaces:

• PRT1 Application/Debug/Config RS-232
• PRT2 Application RS-232, RS-422 or RS-485

PRT2 is jumper configured for direct or multi-drop field communication. The application program can be written to control the two application ports independently, allowing maximum flexibility in the design.

Applications

The MVI94-ADM module is the ideal solution for many applications where serial connectivity must be added to a FLEX platform. Applications using the MVI94-ADM module include:

• Bar code scanner interface
• Legacy ASCII protocol connections
• Terminal port emulation
• Printer driver (Alarm/status printer)
• Customized protocol implementations
