Description
The MVI56-MCM is a Modbus Master/Slave Communication Module manufactured by ProSoft Technology [1, 2, 3, 4]. It’s designed for use with Rockwell Automation ControlLogix processors to enable communication with Modbus devices on a serial RS-485 network [1, 2, 3, 4]. Here’s a breakdown of its functionalities and key features:
-
Function:
- Connects a ControlLogix processor to Modbus devices over an RS-485 serial network. Modbus is a widely used communication protocol for industrial automation systems, allowing various devices from different vendors to communicate with each other.
- Acts as a Modbus master, initiating communication and data exchange with Modbus slave devices (sensors, actuators, etc.) on the network [1, 2, 3, 4].
-
Features:
-
- Supports Modbus RTU and ASCII protocols: The MVI56-MCM can communicate using both Modbus RTU (binary) and Modbus ASCII (text-based) protocols, providing flexibility for integration with various Modbus devices [1, 2, 3, 4].
- Data Mapping: Configuration software allows mapping between ControlLogix data tables and Modbus registers on slave devices. This defines how data is exchanged between the ControlLogix processor and the Modbus network [1, 2, 3, 4].
- Isolation: The module likely provides electrical isolation between the ControlLogix backplane and the RS-485 network to improve noise immunity and protect the controller from electrical faults [1, 2, 3, 4].
-
Applications:
- Industrial automation systems where Rockwell Automation ControlLogix processors need to communicate with Modbus-enabled devices like:
- Sensors (pressure, temperature, flow)
- Actuators (valves, drives)
- Meters
- Other industrial controllers
- Manufacturing facilities
- Oil & Gas Processing Plants
- Chemical Processing Plants
- Power Generation Facilities [1, 2, 3, 4]
- Industrial automation systems where Rockwell Automation ControlLogix processors need to communicate with Modbus-enabled devices like:
-
Considerations (uncertain without user manual):
- The number of supported Modbus slave devices might be limited depending on the capabilities of the MVI56-MCM model and the network configuration [1, 2, 3, 4]. Refer to the user manual for confirmation.
- Advanced features like diagnostics and error handling might be available depending on the module and configuration software [1, 2, 3, 4].
Finding More Information:
Obtaining detailed information on industrial automation parts is essential for proper configuration and operation. Here are ways to learn more about the MVI56-MCM Modbus Master/Slave Communication Module:
- Search Online: Look for “MVI56-MCM user manual” or “MVI56-MCM datasheet” online. You might find PDFs or references on automation parts supplier websites or engineering forums [1, 2, 3, 4]. However, keep in mind the information might be less reliable or outdated compared to ProSoft Technology.
- Contact ProSoft Technology Support: Reach out to ProSoft customer support for the most accurate and up-to-date information on the MVI56-MCM, including:
- User manuals and datasheets
- Compatibility information for specific ControlLogix processor models
- Configuration software details (if applicable)
If you’re working with an MVI56-MCM module or are planning to use one with a Rockwell Automation ControlLogix processor, consulting the user manual and contacting ProSoft Technology support is highly recommended. They can ensure you have the correct information for configuration and communication with Modbus devices on your RS-485 network.
