1. Not a safety or certified control product
Roach Modbus Tool is a Windows application for Modbus TCP/RTU polling, slave simulation, and scripted testing. It is not:
- a safety instrumented system (SIS), SIL-rated device, or protective relay;
- a replacement for a PLC, DCS, BMS, or certified industrial controller;
- a medical, aviation, automotive, or nuclear safety product;
- guaranteed to meet any particular regulatory certification unless we state that in a signed writing for a specific build.
Do not rely on the Software as the sole means of protecting people, property, or the environment.
2. You control the wire
The Software can read and write registers and coils on devices you point it at, and can present simulated Modbus slaves. Incorrect addresses, values, scripts, timing, or slave behavior can disrupt equipment, corrupt process state, trip breakers, or cause downtime.
You are solely responsible for:
- authorization to access each IP address, serial port, and slave ID;
- using a test bench or isolated network when exploring unknown devices;
- reviewing every write, auto-poll, and script before enabling them on production systems;
- validating results against device manuals and your site procedures;
- supervision by qualified personnel where plant or electrical safety rules require it.
3. No guarantee of device compatibility
Modbus implementations vary. Vendors may extend, omit, or interpret function codes differently. We do not warrant that the Software will work with every device, firmware, gateway, or USB–serial adapter, or that compare/script verdicts match your process intent.
4. Software provided “AS IS”
To the maximum extent permitted by law, the Software, documentation, example projects, trial, and Site content are provided without warranties of any kind. We do not warrant uninterrupted operation, freedom from defects, or fitness for your particular plant, product, or deadline.
Limitation of liability amounts and exclusions are set out in the Terms of Use.
5. Unsigned builds and operating-system warnings
Current public builds may be not code-signed. Windows or security software may display SmartScreen or similar warnings. That is expected for unsigned indie software. Download only from this Site or channels we explicitly list. We are not responsible for copies obtained elsewhere, or for decisions your security software makes.
6. Third-party networks, hosts, and tools
Cloudflare or other hosts may deliver the Site. GitHub or other services may host source or releases. Your email provider carries feedback messages. Those parties have their own terms and privacy policies. Device manufacturers are responsible for their firmware and documentation.
7. Website content
Screenshots, feature descriptions, pricing, and roadmaps on the Site are informational. Features may change. Typos or outdated screenshots do not create a warranty. If marketing copy conflicts with the Terms, Privacy Policy, or a written license email we send you, the Terms / Privacy / license email control.
8. No professional advice
Site content and Software UI text are not legal, engineering, or safety advice. You remain responsible for compliance with laws and standards that apply to your project.
