Epochs and CrossEpochs

Epochs

Epochs are time periods that describe a system configuration. When changes are made, e.g. by replacing a connected device, a new epoch is created for your plant.

Example

Epoch 2: "WR 3" was added
Epoch 3: "WR 2" was replaced by "WR 2B

ComponentIds and CrossEpochIds

ComponentIds (id) are newly created per epoch.
CrossEpochIds remain the same over the lifetime of the component.
