8.3.2 Access to the Passive Set of Parameters by Multiple Users
Reading the Passive Set of Parameters
The user interface allows the simultaneous read access of up to 2 users to the passive set of parameters.
Editing the Passive Set of Parameters
The passive set of parameters can only be edited from one user even though multiple users have simultaneous
read access.
Once a user changes a parameter on the user interface, the write access is denied for all other users.
If the write access is blocked, modified in brackets will be displayed in the upper right corner of the user
interface. The user making the changes will see modified without brackets
.
Figure 8-24 Access Blocked
If a user makes a change, the server starts a 20-minute timer. If no further changes to the set of parameters
are entered by the time the timer has counted down, write access is released again for all users. In this case,
the modified data are discarded and the passive set of parameters is overwritten with the content of the active
set of parameters.
If new changes to the passive parameter set are made during the 20-minute countdown, the timer is restarted
by each action.
If the user has completed the changes to the passive set of parameters or finished the parameterization by
clicking Cancel, write access for all users is also released.
