Abstract
We describe how to determine the time delays caused by synchronous and asynchronous control loops. These time delays can vary in a quite irregular way and can cause problems for the control loops closed over a communication network of, for instance, field-buses. Different setups allowing an arbitrary number of communication layers are analyzed. The theoretical derivations are illustrated with a simple but realistic example
