Discontinuations

CODESYS products and product parts also go through a life cycle

CODESYS products in the service phase and discontinued products

Products and product parts go through a life cycle: first they are developed. After their release, they are available for sale and are actively maintained, i.e. security gaps are closed, errors are rectified and further developments usually take place.

If we decide to discontinue a product or part of a product, the service phase begins. In this phase, we no longer sell the product for use in new projects, nor do we continue to maintain it on our own initiative. However, existing customers still have the option of commissioning bug fixes in the form of a service.

The final phase of the product cycle is discontinuation. This can affect a complete product, but also parts or certain features of it.

List of relevant products / product parts that are currently in the service phase or for which a date for entry into the service phase already exists
