Modbus Plus is a legacy but still widely used proprietary network from Schneider Electric (originally Modicon), common in older DCS systems, large motor drives, and plant floor devices. If you have a ControlLogix and need to talk to Modbus Plus equipment, this module is the bridge. It sits in a single slot of the ControlLogix chassis and acts like any other 1756 I/O module to the processor, but on the front it presents a Modbus Plus port. It handles all the complexities of the MBP protocol, including token passing and CRC checking. The processor simply reads and writes data to a block of memory on the MVI56 module, and the module handles the network traffic. This offloads the ControlLogix processor and simplifies your logic. We have these available as tested used and refurbished units.   Frequently Asked Questions (FAQ) Q: Can this module act as both a Master and a Slave on Modbus Plus? A: Yes, it can be configured to operate in Master, Slave, or Multi-Master modes. In Master mode, it initiates read/write requests to other nodes. In Slave mode, it responds to requests from a master. In Multi-Master mode, it can both initiate requests and respond to requests from others. This flexibility is one of its strengths. The configuration is done via the ProSoft Configuration Builder software. Q: I have a new processor. Will I lose the MVI56’s configuration if I replace the ControlLogix CPU? A: No. The module’s configuration is stored in non-volatile memory on the MVI56 module itself. It is independent of the ControlLogix processor. You could pull the CPU and put a different one in, and the MVI56 would continue to operate with its own settings. However, the ladder logic in the new CPU must still read and write to the correct memory locations to exchange data with the module. Q: What’s the maximum number of nodes I can have on the Modbus Plus network with this module? A: The Modbus Plus network itself supports up to 64 nodes. The MVI56-MBP can talk to any of them. The limiting factor in your system will be the amount of data you are moving and the network’s update rate. The module has a 5000-word register space. You have to manage how that memory is mapped to requests for different nodes. In my experience, you can handle quite a few devices if you keep the data per device reasonable. Q: My old MVI56-MBP died. Can I just swap in a new one? A: Yes and no. The hardware is a direct swap. However, you need to ensure the new module has the same configuration as the old one. The configuration includes the node address, baud rate, and all the master command lists. If you have a backup of the old configuration file (from ProSoft Configuration Builder), you can simply download it to the new module. If not, you’ll have to reconfigure it manually, which requires knowing all the devices on the network. A pro tip: always save a copy of the module’s configuration files from PCB when you commission a system. Q: Does this module support Modbus Plus global data? A: Yes, the MVI56-MBP supports the Global Data feature of Modbus Plus. Global Data allows a node to broadcast data to all other nodes on the network without needing individual requests. This is useful for sharing common status or setpoints across multiple devices efficiently. You need to configure the Global Data parameters in the module’s setup. Q: What version of ControlLogix firmware do I need? A: The MVI56-MBP communicates with the ControlLogix backplane using standard input/output tags. It is compatible with a wide range of ControlLogix firmware revisions, from quite old (RSLogix 5000 v15) to modern (Studio 5000 v30 ). The main requirement is that your CPU must support producing/consuming tags. You should always check the specific revision compatibility table in the ProSoft manual for your firmware version, but honestly, in over a decade, I’ve rarely seen a compatibility issue.
