The following are typical situations in which you change the settings for encrypted
communication:
● When a plant experiences a standstill
It is assumed that the communication can fail between any PC stations.
● During ongoing operation of the plant
It is assumed that process mode must always be continually running.
Typical situations:
– Changing settings for encrypted communication
– Software update
Note
Communication between computers with encrypted and unencrypted communication is
only possible in migration mode. You can find additional information on migration mode in
the section "How to use migration mode for changing encrypted communication
(Page 119)".
● Changing password for encrypted communication (changing a PSK in a plant)
You can find information on this in the section "How to change the PSK for encrypted
