Top ModSim Alternatives for Modbus Simulation

ModSim32, often referred to simply as ModSim, is a powerful yet simple application designed for simulating data from Modbus slave devices. It's an MDI application that allows users to define multiple blocks of data points, accessible by a connected Modbus master. While ModSim is excellent for compliance testing, quick process simulation, and even network connections with OLE Automation, users sometimes seek ModSim alternative options for various reasons, including specific feature needs, platform compatibility, or open-source preferences. This article explores some of the best alternatives available.
