Native Modbus TCP client blocks enable communication between real-time target machines and external devices in power grids and automation plants.
The driver blocks handle the data exchange between the connected Modbus TCP servers and the application running on the real-time target computer.
Modbus TCP is ideal for rapid control prototyping (RCP) of control stations such as supervisory control and data acquisition (SCADA) systems and programmable logic controllers (PLC). It also enables hardware-in-the-loop (HIL) simulation using MATLAB and Simulink for testing remote servers such as motor drives, sensors, and intelligent electronic devices (IED).
Get started with Modbus TCP by adding the driver blocks to your Simulink model. No additional tools are required to get it running. Native Modus TCP is supported both on the Ethernet interfaces of the real-time target machines and over plug-in Ethernet I/O modules (see Hardware Selection Guide).
- Data exchange with up to 256 Modbus TCP servers
- Supports unit addressing
- Supports access to coils, discrete inputs, holding registers and input registers of external servers
- Supports codes FC1, FC2, FC3, FC4, FC5, FC6, FC15 and FC16 function codes
- Asynchronous data exchange saves computing time for real-time tasks
- Multiple client stations can run on one target machine, either controlling servers in the same network or separate networks
