This list is not exhaustive; additional trademarks may appear in documentation pages, comparison tables or language references.

All mentioned trademarks, product names and company names are the property of their respective owners and are used on this website exclusively for:

  • identification in factual information,
  • technical comparison in the reference documentation (e.g. dialects of IEC 61131-3, discussion of different standard library implementations, vendor data formats),
  • interoperability description (e.g. supported fieldbus protocols, importable device-description formats).

Mention does not imply cooperation, licensing or endorsement by or towards the ForgeIEC project. ForgeIEC has no business, organisational or contractual relationship with the trademark owners listed above, unless explicitly stated otherwise.

ForgeIEC is an independent implementation of IEC 61131-3 (an open industry standard of the IEC) and is not a derivative, port or clone of any commercial product.

Please contact us before issuing a cease-and-desist

If you believe that this website or the ForgeIEC project makes unauthorised use of trademark, copyright or personality rights, we explicitly ask you to send a brief informal email to:

blacksmith@forgeiec.io

Because the project generates no revenue and pursues no commercial interests, an immediate fee-incurring legal cease-and-desist would be disproportionate under the established case law of DACH jurisdictions (see, among others, BGH, judgment of 12 December 2013, I ZR 131/12). The project maintainer takes responsibility seriously and will respond to any substantiated complaint without delay:

  • the disputed content will typically be removed or changed within 48 hours,
  • a binding declaration to cease and desist will be issued voluntarily where an infringement actually exists,
  • the costs of an initial legal letter will be rejected as unfounded because, absent prior direct contact, such costs are neither necessary nor proportionate.

We therefore ask for understanding that we will reject legal fee notes that are issued without prior direct contact as a matter of principle.
