SimServe Modbus Device Simulator
Overview
-
SimServe is a Modbus device simulator, sometimes referred to as a Modbus slave simulator. With minimal configuration, it acts as a simulator for Modbus RTU slaves, Modbus ASCII slaves, and Modbus TCP slaves.
-
Connect SimServe to any Modbus Master such as a SCADA system or PLC, and SimServe will respond to Modbus requests as if it were the real slave device.
-
Use SimServe to simulate a sophisticated Modbus network with different gateways and a mix of Modbus protocol variants. SimServe will handle the Modbus RTU, Modbus ASCII, and Modbus TCP conversions.
Use Cases
Simulate a single Modbus device
Say you’re developing a SCADA program that must communicate to a Modbus slave device, and you don’t have a physical Modbus device to connect. Connect your program to SimServe instead!
Simulate a complicated network of Modbus devices
You’re developing a SCADA system that will communicate to several field controllers across a complicated network like this one:
Setting up a physical replica of the network for development is out of the question, but you still need some way to verify communication during development. Use SimServe to simulate the network and field devices like this:
Now your development environment matches production, there’s no need for extensive configuration tweaks during deployment, and you’ve eliminated serious startup risk!
