MVI69L-MBS ProSoft Technology Modbus Serial Module CompactLogix

The MVI69L-MBS, Modbus Serial module for the CompactLogix™ series of controllers is designed for smaller applications where communication between a few Modbus Serial devices is required. This module has an Add-on Profile and an Add-on Instruction to reduce commissioning time. The MVI69L-MBS has a single serial port and can support either Master or Slave connectivity to interface with a variety of devices using the Modbus Protocol.

Features and Benefits
-Supports CompactLogix processors with 1769 I/O bus capability version 16 and greater (MicroLogix 1500 not supported)
-Add-on Instruction creates UDTs, providing logical definitions for I/O, status, and control data
-Add-on Profile support, improving integration in the CompactLogix System
-Diagnostic data available in processor controller tags, enabling decisions to be made based upon node health
-Module configuration backed up in CompactLogix project (ACD file)
-Module acts as a co-processor reducing impact to PLC scan time
-Supports up to 240 words of I/O data
-Application port can be configured as either a Modbus Master or Modbus Slave
-Supports up to 30 Modbus Commands as a Modbus Master
-Supports Enron and Daniel style Floating point data implementations
-Most suitable for OEM and Machine Builder applications
