Description

The ProSoft MVI69L-MBS is a high-performance Modbus Serial Lite communication module engineered specifically for integration with Rockwell Automation CompactLogix L1, L2, and L3 processors. This module acts as a specialized bridge between the PLC backplane and external Modbus RTU or ASCII devices, functioning as either a Master or a Slave. By offloading communication tasks from the main processor, the MVI69L-MBS ensures efficient data throughput and system stability in demanding industrial automation environments.

Features

• Supports Modbus RTU and Modbus ASCII protocols.
• Configurable as Modbus Master or Slave for flexible network architecture.
• Optimized for CompactLogix backplane integration with minimal CPU overhead.
• Wide baud rate support ranging from 110 to 115.2K.
• Rugged hardware design suitable for high-EMI industrial environments.
• Compact footprint for space-constrained control cabinets.

Applications

The MVI69L-MBS is widely deployed in sectors requiring reliable serial connectivity, including oil and gas refineries, power generation, mining, and water treatment facilities. It is ideal for interfacing with variable frequency drives (VFDs), power meters, flow computers, and other serial-enabled instrumentation within a SCADA or distributed control network.

Technical Specifications

Installation Guidelines

• Ensure the CompactLogix processor is powered down before inserting or removing the module from the backplane.
• Verify that the module is securely seated in the chassis to ensure proper backplane communication.
• Use shielded serial cables for all connections to maintain signal integrity and minimize EMI interference.
• Ensure proper grounding of the control cabinet to protect against electrical noise.
• Maintain adequate ventilation around the module to ensure operating temperatures remain within the 0 to 60 deg C range.

FAQ

Does this module require external power?

No, the MVI69L-MBS draws its power directly from the CompactLogix backplane (5 VDC).

Can this module function as a Master and Slave simultaneously?

The module is configured for specific roles; please refer to the ProSoft configuration software to define the port as either a Master or a Slave to suit your network architecture.

Is this compatible with all CompactLogix processors?

It is designed for use with CompactLogix L1, L2, and L3 processors. Please verify your specific processor firmware and backplane compatibility before installation.
