Disclaimer
What Maatron results say, what they do not say, and where our responsibility stops once an engineer decides on the strength of them.
Last revised:
Decision support, not a certification
Maatron reads a backup archive and reports what is in it. It is engineering decision support.
It is not a certification. No result attests that an installation is safe, that it meets a standard, or that it is fit to run. We issue no attestation and no inspection body opinion, and an exported report must not be presented as one.
A finding states a fact read in a file, together with where that fact came from. What follows from it — a defect, a deliberate choice, or a particularity of your installation — is for the engineer who knows the cell.
A backup is partial by nature
A backup holds what the controller exported at the moment it was taken. No more, and nothing else. Depending on the backup type, the controller model, its software version and the options installed, whole areas of the configuration may simply not be in it.
As a result, the absence of an item from a result means "not provided", never "none". An empty section does not say there is nothing there: it says the file is silent about it.
This is the most consequential misreading available here, and the product is built to block it: whatever could not be read is flagged as not covered, kept apart from the findings, rather than counted as a zero.
If part of your cell is missing from a result, the first question is about what the backup contains, not about the state of the installation.
A file, not a cell in operation
The service does not observe the live state of a cell. It does not connect to one, does not measure it, and does not know whether it is running. It describes a file, and that file describes a past state.
Between the moment the backup was taken and the moment you read the result, a parameter may have been changed, a program replaced, a sensor moved, an option added. A result is therefore dated by the backup it came from, never by the day you open it.
No safety-related decision should rest on a result without checking, on the installation itself, that it is still current.
Deterministic does not mean exhaustive
The analysis is deterministic: the same files, on the same engine version, give the same findings. That is a guarantee of reproducibility and auditability, and it is a real one.
It is not a guarantee of completeness. The engine applies the rules it has: it does not find what no rule looks for, nor what an unrecognized format hides from it.
An absence of findings therefore does not mean "nothing to report". It means "nothing that these rules, on these files, detected". Every result carries the engine version that produced it, so that this scope stays verifiable afterwards.
The decision belongs to a qualified engineer
A result is a working document. It becomes a decision when a competent person reads it, checks it against the real installation, and rules on it.
That person is yours: the engineer, the machine safety lead, or the licensed professional who puts their signature to it. [À COMPLÉTER — raison sociale] carries out no engineering assignment on your site, signs no drawing, and takes no role as designer or operator of your installation.
We answer for the service reading and reporting faithfully. We do not answer for what is done with a result, nor for the work, shutdowns or restarts decided on the strength of one. Terms of Service sets the general frame for that division.
Your regulatory obligations remain
Nothing here reduces your obligations as an operator: machinery safety, risk assessment, lockout, training, notices to the competent authority. In Quebec, the Act respecting occupational health and safety and its regulations apply whatever use you make of the service; elsewhere, the equivalent rules of your own jurisdiction do.
Using Maatron relieves you of no inspection, no validation, no document those rules require. The service can help you prepare them; it does not stand in for them.
Scope of this notice
This notice covers every output of the service: findings, cell model, generated documentation, version comparisons and exports. It follows the result when that result is exported and circulated outside the service.
AI-assisted analysis, where it is offered to you, stays optional and separate from the deterministic path. Its output is not reproducible in the same sense, and everything above applies to it with more force still.
This notice forms part of Terms of Service, whose limits of liability it makes precise without widening them. A question about the scope of a particular result goes to info@maatron.dev: we would rather answer before a decision than after.
