Selection Guide
Native Modbus TCP runs on the CPU. This is supported with onboard Ethernet interfaces and plug-in Ethernet I/O modules. One Ethernet port can handle the data transmission of multiple Modbus nodes configured in the real-time application (client, server, or both). Each Modbus node requires a run-time license. Native Modbus TCP support is available with MATLAB® R2020b and later.
The following native implementations are available:
In addition to onboard Ethernet support, native Modbus TCP is compatible with the following Ethernet I/O modules:

The IO75x I/O module series provides dedicated Modbus TCP I/O modules for single-node and multi-node applications. One module acts either as a single Modbus TCP node or a whole network of Modbus nodes. This solution ensures deterministic transmission of client queries and short response times to queries in the server because the protocol stack runs on the I/O module. IO75x I/O modules do not require run-time licenses.
