Modbus Device Driver

Learn how to acquire data from and control Modbus TCP servers using Synnax.

Modbus protocol allows the Synnax Driver to connect to a wide range of industrial devices and PLCs that support Modbus TCP/IP communication.

Supported Protocol

The Synnax Driver supports Modbus TCP/IP, which is the Ethernet-based variant of the Modbus protocol. Modbus TCP is one of the most widely supported industrial protocols and is commonly used for:

  • Programmable logic controllers (PLCs)
  • Variable-frequency drives (VFDs)
  • Power meters and energy monitoring devices
  • Temperature and humidity controllers
  • Industrial I/O modules
  • Building automation systems

Modbus RTU (serial) and Modbus ASCII protocols are not supported.

Supported Operating Systems

Windows✓ Supported
Linux✓ Supported
NI Linux Real-Time✗ Not Supported
macOS✓ Supported
Docker✓ Supported

When running in a Docker container, ensure the container has network access to the Modbus server(s).



Modbus TCP is not available on NI Linux Real-Time controllers (CompactRIO, PXI systems). For these platforms, use the NI or OPC UA device drivers if your hardware supports it.
