An automation engineer is looking to deploy a deterministic network in a sheet metal factory. The control system in charge of safety expects a message from the embedded application of a heating element controller every 50 milliseconds, otherwise, it immediately shuts down the production line. The network in question has on average a delay of 1 msec per link and 2 msec per node. What is the maximum number of hops that can separate the control system from the heating element controller?
