*How to estimate DAT and HAT?*

## Estimation of Device Ack Time (DAT) and Host Ack Time (HAT)

### Estimation of Device Ack Time (DAT) and Host Ack Time (HAT)

Question from the PROFIsafe Designer Workshop in October 2023:

These values are dependent on your implementation details. You will investigate worst-case times of "how long these things take".

There was also the question whether these values are parameterizable. The answer to this is "no"; you have to specify stable upper bounds (for the time-wise worst case scenarios of your implementation).
