One aspect of PLCopen's work is the certification of IEC 61131-3 compliant programming systems. The starting point is a document titled "PLCopen Guideline: Compliance Testing & Certification". A product can be certified as IEC 61131-3 compliant at the following levels:
- a Base Level (BL) compliant product indicates that the vendor is a serious member of the IEC 61131 community and is committed to use the standard syntax.
- a Conformity Level (CL) compliant product shows a much higher level of conformance with the standard. In addition, via the combination with
- a Reusability Level (RL) users are able to interchange Function and Function Block definitions with other RL compliant products.

Compliance testing must be performed by a test laboratory accredited by PLCopen according to the figure shown below. Accreditation will be effective for a 4 year period after which an application for re-accreditation must be made.
Certification
Certification of a product as IEC compliant will be performed by PLCopen after compliance testing has been carried out by an accredited test laboratory. The testing will be performed under a private arrangement between the test laboratory and the applicant. PLCopen will only become involved when the applicant submits an application for certification accompanied by a successful test report issued by the test laboratory. PLCopen will not be notified that the test is taking place and will not be informed of any failed test. Certification of a system lasts for 3 years and covers subsequent versions of the system which are declared by the vendor to be compliant. After 3 years the latest version of the system must be re-tested and re-certified.
Certification of products is exclusively for PLCopen members. The document "PLCopen Guideline: Compliance Testing & Certification" is available for members.
