Company and product

Terms of use

Starter permits learning and evaluation without a key or expiry. Test runs prepared projects with read-only system preparation. Engineering creates systems and delivers projects. Equipment count and project size are not limited by edition. Test permits opening, copying, activating and running prepared .modbussim projects, adjusting local TCP/serial settings, running saved tests, and exporting results or unchanged tested copies. Creating or editing systems, models, mappings, logic or test scenarios and saving changed preparation require Engineering. A manually issued Engineering trial lasts 14 days; expiry returns usage to Starter without removing tools or altering projects and results. Signed usage licenses retain machine, duration and release checks. Existing agreements remain applicable.

• Do not copy, resell, sublicense, reverse engineer, or redistribute ModbusSim except where a written agreement allows it.
• Use simulation results as engineering test evidence, not as a guarantee of physical machine performance or site commissioning outcome.
• Keep license keys, Machine IDs, project files, exported reports, and configuration packages under your own control.
• Support may require the release number, final .modbussim project with its Plant Test scenario, endpoint and map details, expected result, actual result, screenshots, logs, reports, or evidence files.
• Prices, duration, machine coverage, release coverage, support and custom services are confirmed in the written quotation. Test preparation is read-only; Engineering permits authoring.

Privacy notice

The website may collect name, email address, company or project name, Machine ID, support details, and message text when a request form or support email is submitted. This information is used to respond to installer requests, trial-license requests, license questions, support cases, and commercial inquiries.

ModbusSim does not need buyer card details for website forms. When Paddle checkout is enabled, payment information is entered through Paddle and handled under Paddle's own legal terms and privacy notice.

Requests sent by email or form may be retained as business records so support history, license decisions, and payment or refund questions can be reviewed later. To request correction or deletion of personal information held by Systèmes ModbusSim Inc., contact info@modbussim.com.

Refund and return policy

ModbusSim is digital software. No physical goods are shipped, so a return normally means a refund request and cancellation or removal of access to the relevant license.

• Before Paddle checkout is enabled, trial and evaluation requests are handled manually by email and may not involve an online payment.
• For paid Paddle orders, refund and return requests should be submitted through the Paddle receipt, Paddle buyer portal, or paddle.net.
• Where local consumer law grants non-waivable refund or withdrawal rights, those rights continue to apply.
• Technical or product-defect concerns should first be sent to info@modbussim.com so the issue can be reproduced or corrected when possible.
• If a paid usage license is refunded, its usage rights may end. Permanent Starter and its tools remain available.

Paddle order processing

When online checkout is enabled, the order process is planned to use Paddle.com as the online reseller and merchant of record. Paddle handles payment processing, sales-tax handling, receipts, buyer payment support, refunds, and returns for Paddle orders. Systèmes ModbusSim Inc. remains responsible for the ModbusSim product and product support.
