Why Do We Use A Wired Connection To Configure The Join Key & Network Id In Wireless Hart? |
|
Answer» Since users demand a high level of data and network security, the join key and network I.D. are never broadcasted across the network. HOWEVER, if the network I.D. and join key are configured at the FACTORY a LOCAL WIRED connection is not needed for device configuration. Once the device joins a network, the initial join key is changed. Since users demand a high level of data and network security, the join key and network I.D. are never broadcasted across the network.
