Modbus TCP Conformance Testing

The true benefit of any open standard is the assurance it provides to users that the products they buy will interoperate seamlessly. Unfortunately, any specification, no matter how carefully written, is subject to interpretation and occasional misunderstanding. That's where conformance testing becomes valuable.

The Modbus Conformance Testing Program provides independent verification that a broad array of qualifications has been met in compliance with Modbus specifications. It provides end users with the comfort that their design and configuration process will proceed smoothly and assures suppliers that their products were developed in accordance with key Modbus criteria.

The Modbus Conformance Test Committee has completed a revision of the Modbus Conformance Test Program at the request of the organization's Board of Directors. The new program includes two options:

  • Conformance testing under a controlled self-test program for member companies.
  • Conformance testing by approved third-party test laboratories in the United States, Europe, and Asia.
