MVI69E-MBS | Modbus Serial Communication Module

Key Features and Advantages

Seamless ControlLogix Integration: The MVI69E-MBS installs directly into ControlLogix chassis as a local module, enabling native Modbus communication without external gateways or additional controllers.

High-Performance Data Exchange: Capable of processing up to 1000 registers per second, this module ensures real-time data synchronization between ControlLogix processors and Modbus devices.

Flexible Configuration: The RS-232/485 port supports both master and slave modes, allowing the MVI69E-MBS to initiate requests to Modbus devices or respond to requests from Modbus masters.

Robust Diagnostics: Comprehensive status indicators and detailed error reporting simplify troubleshooting. The module continuously monitors communication health and automatically recovers from transmission errors.

Easy Programming: Configuration through Rockwell Studio 5000 using Prosoft’s intuitive add-on instructions (AOIs) eliminates the need for separate configuration software.
