Modbus Master
The Modbus Master Simulator I/O interface connects with various Modbus slave devices to send read and write commands in real-time simulation environments. Operate the interface over TCP/IP via an Ethernet link or over RTU using a serial link (RS232/RS485). This versatile setup allows the Modbus RTU Master Simulator to function effectively over RS485 and the Modbus TCP Master Simulator to communicate seamlessly over standard networks.
Learn more about Modbus Master
Modbus, a data communications protocol introduced by Modicon (now Schneider Electric) in 1979, was designed for use with programmable logic controllers (PLCs). Today, Modbus is a de facto standard for connecting industrial electronic devices, widely applied in industrial automation and energy systems.
With a standard network interface card, Modbus TCP integrates quickly into any simulation model. Once configured, the driver initializes on the target simulator at the start of the simulation, connecting to all configured slave devices to begin data transmission. This functionality is essential for users working with Modbus Master Simulator Software and Modbus Master Devices in HIL or SIL testing setups.

FAQ
Find the answers to your questions
What is a Modbus Master Simulator and how does it work in OPAL-RT systems?
A Modbus Master Simulator is a software tool that enables communication with Modbus slave devices to send and receive data. Our Modbus Master Simulator connects through TCP/IP or serial links (RS232/RS485) and initializes on the target simulator to begin real-time data transmission at the start of the simulation.
Can OPAL-RT’s Modbus Master Simulator Software operate over both RTU and TCP protocols?
Yes, the Modbus Master Simulator Software supports both Modbus RTU Master and Modbus TCP Master protocols. You can operate it via RS485 for RTU or Ethernet for TCP, ensuring compatibility across different simulation environments and test setups.
Is the Modbus Master Slave Simulator compatible with RT-LAB and HYPERSIM platforms?
Absolutely. The Modbus Master Slave Simulator integrates seamlessly with both RT-LAB and HYPERSIM platforms, allowing real-time communication between Modbus Master Devices and slave units for dynamic testing and validation.
How does the RS485 Modbus RTU Master configuration support real-time communication?
In RS485 Modbus RTU Master setups, our interface uses a serial link to connect with Modbus slave devices. This ensures low-latency, deterministic communication for high-performance simulation environments using RT-LAB or HYPERSIM.
What types of applications can benefit from using a Modbus TCP Master Simulator with OPAL-RT?
The Modbus TCP Master Simulator is ideal for industrial automation, energy systems, and hardware-in-the-loop testing. It enables seamless Ethernet-based communication between a Modbus Master Device and multiple slave units in real-time simulation environments.
