What is Modbus?

Modbus is a industrial protocols widely used among control system and by many vendors categorized as a standard for secondary equipment such as meters, sensors etc.. Originally developed by Modicon in 1979 it was designed to enable communication between OT equipment, sensors and other equipment.
The original Modbus is based on serial communication on RS-232 or RS-485 and was in 2000 expanded to also support communication on ethernet. It comes in 3 major variations for communication medium:

  • Modbus RTU (RS-232 or RS-485)
  • Modbus TCP
  • Modbus RTU over TCP (RTU encapsulated in TCP to bridge the two)

Since Modbus is an open standard without strict definitions for endianness, byte ordering, or string swapping, there are many variations in how data is packed, leading to differences in implementation across devices.

Frequenctly Asked Questions about Modbus

What Modbus variations are supported?

We support the following Modbus variations:

  • Modbus TCP
  • Modbus RTU (RS232 and RS485)
  • Modbus RTU over TCP

The following data variations are supported:

  • Endianness: Big endian and Little endian
  • Byte Order: First byte high and First byte low
  • String Endianness: Big endian and Little endian
  • String Byte Order: First byte high and First byte low

As some vendors has different endianness and byte order for strings and numeric values you can select individually

 

The solution are capable of integration bi-directionally with most cloud and end-point services using one the below Connectors:

  • MQTT
  • REST API
  • Azure IoT Hub: Including Device Provisioning Service (DPS) and digital twins for comprehensive device management.
  • AWS
  • Alibaba Cloud
  • Google Cloud
  • Siemens MindSphere
  • Apache Pulsar
  • Generic files (CSV, JSON, XML, plain text, etc. to FTP)
  • Any cloud platform using one of the above technologies:
    • Aveva Insight

    • and many more…

The solution can translate Modbus to any of the other protocols supported by SIA Connect:

  • Ethernet/IP
  • BACnet IP
  • BACnet MS/TP
  • Beckhoff TwinCAT ADS
  • Ethernet/IP
  • IFM VSE series
  • Keyence KV Ethernet
  • Mitsubishi MELSEC
  • Modbus TCP
  • Modbus RTU
  • Modbus RTU over TCP
  • M-Bus
  • MTConnect
  • Wireless M-Bus (wM-Bus)
  • NITP in CAMP (TI505)
  • OPC-UA client
  • OPC-UA server
  • Siemens S5
  • Siemens S7
  • Siemens LOGO!
  • Omron FINS TCP & UDP
  • Omron Host Link
  • Universal Robots RTDE

The solution can exchange data with the following databases:

  • MS SQL
  • Azure SQL
  • PostgreSQL
  • MySQL / MariaDB
  • InfluxDB (REST API)
  • MongoDB (REST API)

Modbus RTU over TCP is a variation of the Modbus protocol that encapsulates Modbus RTU messages within TCP/IP packets. This allows traditional Modbus RTU communication to be performed over Ethernet networks, combining the simplicity of RTU with the reliability and widespread use of modern network infrastructure. It also allows the serial network to be integrated with an Ethernet network and also enables exchange information across multiple Modbus RTU networks.

  • MS SQL
  • Azure SQL
  • PostgreSQL
  • MySQL / MariaDB
  • InfluxDB (REST API)
  • MongoDB (REST API)
