What does determinism mean for an industrial network?

  1. The network never changes its topology, even when nodes are added or removed
  2. The network uses only fibre, so the signal cannot be delayed
  3. There is a guaranteed maximum time for data to get from one node to another
  4. The network has no master, so every node can talk freely
Show answer

Correct answer: There is a guaranteed maximum time for data to get from one node to another

A deterministic network is needed when control actions must arrive on time.
