Downgrade of TwinCAT 3 standard licenses

Downgrade of TwinCAT 3 standard licenses 1:

The downgrading of TwinCAT 3 licenses works only with a TwinCAT 3 license dongle.

The downgrade options for TwinCAT 3 standard licenses depend on the TwinCAT version used.

From TwinCAT 3.1, build 4022

It is possible to downgrade TwinCAT 3 standard licenses. For example, you can use a USB dongle whose licenses have been activated for platform level 80 for lower platform levels (e.g. 20-70).

Platform level 90 covers only platform level 80 and lower, not platform level 81, 82, 83, ...

Up to TwinCAT 3.1 Build 4020 (inclusive)

TwinCAT 3 standard licenses can only be used for exactly the same platform level as the activation. For example, you can use a USB dongle whose licenses have been activated for platform level 80 for lower platform levels (e.g. 20-70).

Specification of the platform level of TwinCAT 3 standard licenses during activation

Note that when activating a TwinCAT 3 standard license, the platform level of this license is permanently set.

The platform level during activation may be lower than the level specified in the order. However, once activated the platform level cannot be changed.

Example:

The platform level in the order is 80. Activation takes place for platform level 50. Now the license can only be used for platform level 50 (and lower (build 4022 only)). This cannot be changed retrospectively.
