Rights for remote access
The "Specified by PLC" field shows the access rights for remote access or remote monitoring
specified from the PLC.
In the "Selected in the HMI" selection box, you have the possibility of setting rights for remote
control:
● Do not permit remote access
● Permit remote monitoring
● Permit remote control
Depending on the combination of the settings in the HMI and in the PLC the valid status as to
whether access is permitted or not is shown in the "Resulting from this" line.
Settings for the confirmation dialog box
If the settings made for "Specified from the PLC" and "Selected in the HMI" permit access from
outside, then this is however, still dependent on either a manual or automatic confirmation.
As soon as a remote access is permitted, at all of the active operating stations, a query dialog
box is displayed for the operator at the active operating station to either confirm or reject an
access.
For the case that there is no local operation, then the control behavior can be set for this
particular scenario. You define how long this window is displayed and whether, after the
confirmation has expired, the remote access is automatically rejected or accepted.
Display of the state
If remote access is active, using these icons you will be informed in the status line as to whether
a remote access is presently active or whether only monitoring is permitted.
