For years, engineers testing PLC (Programmable Logic Controller) communications would stumble upon a small, unassuming program called ModRSsim. It was a "labor of love" created to simulate multiple Modbus RTU and TCP/IP stations at once.
However, the program had a famous quirk. If you didn't have a registration key, the software would run perfectly for exactly 45 minutes. After that, it didn't shut down or lock you out; instead, it began to "annoy" you. A popup would appear every 60 seconds, gently reminding you that while the version was fully functional, it was unregistered.
The developer didn't want money—they wanted a connection. The "nag" screen was intentionally designed so that users would reach out. As the source code revealed, the message read: "To obtain a totally free key, see the Help-About window!". For many old-school engineers, getting that "new" registration key meant sending a quick email to the creator, essentially saying "Thank you" in exchange for a lifetime of silence from the reminder popup. The New Era: ModRSsim2
As technology moved forward, a new chapter began. In late 2014, a developer working on a project needed a reliable Modbus simulator and rediscovered the original code. This led to the birth of ModRSsim2, a modernized fork.
The "new" way to use ModRSsim2 removed the hurdle of the registration key entirely. Because the project is now fully open-source and hosted on platforms like SourceForge and GitHub, the community-driven version is completely free without the 45-minute "annoyance" timer. ModRSsim Quick Facts
Purpose: Simulates Modbus devices (Servers/Slaves) to test Master software or hardware.
Key Feature: Can simulate up to 255 device IDs simultaneously.
Legacy: The original version used a "Registration Reminder" function to encourage user feedback. modrssim/src/mod_RSsim/About.cpp at master - GitHub
