PROSOFT MVI69E-MBS
2. Product introduction
The ProSoft MVI69E – MBS is a specialized Modbus Serial Enhanced Communication Module designed to meet the demands of applications that require seamless Modbus serial connectivity within CompactLogix environments. By integrating this module, CompactLogix systems can efficiently interface with a diverse range of devices that operate on the Modbus protocol.
For example, in a building automation system, the CompactLogix controller, equipped with the ProSoft MVI69E – MBS, can communicate with Modbus – enabled sensors and actuators. The module can map data from temperature sensors (input) and send control commands to HVAC system dampers (output) using the Modbus protocol. This integration streamlines the building’s control system, allowing for better energy management and environmental control.
3. Core advantages and technical highlights
3.1 User – defined data types (UDTs) creation
The ProSoft MVI69E – MBS has the ability to create user – defined data types (UDTs) through its add – on instruction. This feature provides logical definitions for I/O, status, and control data. In a manufacturing plant, when connecting to Modbus – based production line sensors and controllers, the UDTs can be customized to group related data. For instance, data related to a specific production process, such as sensor readings from a packaging machine (input) and control signals for its operation (output), can be grouped into a single UDT. This simplifies data management and programming, making it easier for engineers to understand and work with the data flow within the CompactLogix system.
3.2 Add – on profile support
With add – on profile support, the module significantly improves its integration within the CompactLogix system. This support allows for a more seamless connection and interaction between the module and the CompactLogix processor. In a wastewater treatment facility, where multiple CompactLogix – based control panels are used, the ProSoft MVI69E – MBS with add – on profile support can be easily integrated into the existing CompactLogix network. It can communicate with Modbus – connected pumps, valves, and level sensors, and the add – on profile ensures that the data transfer and control operations are optimized for the CompactLogix environment, enhancing the overall system performance.
3.3 Co – processor functionality
The module functions as a co – processor, which has a major advantage of reducing the impact on the PLC scan time. In applications where real – time data processing is crucial, such as in a high – speed assembly line in an automotive factory, the ProSoft MVI69E – MBS can handle Modbus – related data processing tasks independently. It can quickly communicate with Modbus – based robotic arm controllers (input for position feedback and output for movement commands) without overloading the main PLC scan cycle. This ensures that the overall system can respond rapidly to changes in the production line, minimizing downtime and improving productivity.
4. Typical application scenarios
4.1 Building automation
In large commercial buildings, the ProSoft MVI69E – MBS can be used to connect CompactLogix – based building management systems to a wide range of Modbus – enabled devices. It can transfer data from lighting control systems (input for occupancy sensor readings) and send control commands to adjust lighting levels (output). Additionally, it can interface with Modbus – connected heating, ventilation, and air – conditioning (HVAC) equipment, enabling centralized control and monitoring. This helps in creating a more energy – efficient and comfortable building environment.
4.2 Manufacturing
On the factory floor, the module plays a vital role in connecting CompactLogix controllers to Modbus – based production equipment. For example, in a food and beverage manufacturing plant, it can communicate with Modbus – enabled filling machines (input for fill level sensors and output for start/stop commands), conveyor belts (input for speed sensors and output for control of conveyor movement), and packaging equipment. This enables seamless integration of different production processes, improving production efficiency and product quality.
4.3 SCADA and field device interface
In industrial SCADA (Supervisory Control and Data Acquisition) systems, the ProSoft MVI69E – MBS serves as a bridge between CompactLogix – based local control systems and Modbus – connected field devices. In a power generation plant, it can transfer data from Modbus – enabled power meters (input for voltage, current, and power readings) to the CompactLogix system, which can then process the data and send control commands (output) to equipment such as circuit breakers or voltage regulators. This allows for real – time monitoring and control of the power generation and distribution process, ensuring reliable power supply.

6. Installation, commissioning and maintenance instructions
6.1 Installation preparation
Before installing the ProSoft MVI69E – MBS, ensure that the CompactLogix chassis (1769) has an available empty slot. Power off the CompactLogix system to prevent any electrical damage during installation. Wear an ESD (Electro – Static Discharge) wristband to protect the module from electrostatic discharge, which can potentially damage the sensitive electronic components. Align the ProSoft MVI69E – MBS module with the chassis guides and gently but firmly push it into the slot until it is fully seated. Apply even pressure to avoid bending any pins. Once installed, power on the CompactLogix system and check the module’s power LED. If it illuminates, it indicates that the module has established communication with the backplane.
6.2 Connecting Modbus devices
Use suitable Modbus – compliant cables (such as shielded, twisted – pair cables) to connect the ProSoft MVI69E – MBS to the Modbus devices. Connect the cables to the serial ports on the module. For each serial port, configure it as either a Modbus master or slave according to the application requirements. This can be done using the ProSoft Configuration Builder software. Set the appropriate communication parameters such as baud rate, stop bits, and data size to match those of the Modbus – connected devices. If the module is communicating with multiple Modbus devices on a single port, ensure proper addressing and protocol settings to avoid communication conflicts.
6.3 Maintenance suggestions
Regularly inspect the ProSoft MVI69E – MBS module for any signs of physical damage or loose connections. Check the LEDs on the module (if available) to monitor its status. A green LED may indicate normal power and communication, while a red LED may signal an error. Periodically clean the serial connectors with compressed air to remove any dust or debris that could affect the communication quality. In case of communication failures, use the ProSoft Configuration Builder software to check for issues such as incorrect communication parameter settings, improper Modbus command configurations, or problems with the Modbus – connected devices. Update the module’s firmware as recommended by ProSoft Technology to ensure compatibility with the latest Modbus standards and to fix any known bugs or security vulnerabilities.
