Channel hopping is performed Data link HART layer.
Option (2)
Explanation:
- The data link layer incorporated the use of superframes and 'time dimension multiple access' (TDMA) technology to support collision-free, deterministic communication.
- The Superframes are used to monitor transmission timing to ensure efficient communication and minimize collisions.
- The data link layer uses channel hopping and channel blacklisting to increase security and reliability. Through channel hopping, the channel is switched each time a transmission occurs. Channel blacklisting defines channels that are repeatedly influenced by the intrusion and bans them from use.
