Understanding the difference between these modules is critical for selecting the right solution:
| Feature | MVI56-MNET | MVI56-MNETR |
|---|---|---|
| I/O Image Size (Input) | 250 words | 42 words |
| I/O Image Size (Output) | 248 words | 42 words |
| Best Application | Local chassis installations | Remote chassis / bandwidth-limited networks |
| Remote Rack Suitability | May exceed ControlNet bandwidth | Optimized for remote rack use |
Key Advantage of MNETR: The reduced I/O image size uses significantly less bandwidth on process control networks like ControlNet or EtherNet/IP. This makes the MVI56-MNETR the preferred choice for remote rack installations where network bandwidth is a critical resource.
When using ControlNet to access a remote ControlLogix chassis, I/O bandwidth limitations can become a significant issue. Standard MVI56 modules require 250 words of input and 248 words of output—a data load that may exceed available ControlNet bandwidth, depending on other modules in the chassis.
The MVI56-MNETR addresses this challenge with its reduced data block design:
| Component | Standard MVI56 | MVI56-MNETR |
|---|---|---|
| Input Words | 250 | 42 |
| Output Words | 248 | 42 |
| Bandwidth Usage | High | Reduced by ~83% |
The module uses an RPI (Requested Packet Interval) of 5 ms as a good starting value, configurable from 0.2 to 780.0 ms depending on application requirements.
The MVI56-MNETR is ideal for Modbus TCP/IP integration in remote chassis applications:
| Industry | Application |
|---|---|
| Oil & Gas | Connecting Modbus TCP/IP devices to ControlLogix in remote wellhead and pipeline control cabinets |
| Manufacturing | Remote I/O racks in large plants where ControlNet bandwidth must be conserved |
| Water/Wastewater | Distributed SCADA systems with ControlLogix in remote pumping stations |
| Food Processing | Integration with Modbus-compatible instrumentation in production lines |
| Pulp & Paper | Connecting Modbus TCP/IP drives and instruments in remote control cabinets |
| Automotive | Factory automation systems with distributed ControlLogix racks |
