Setting remote access

You can influence the remote access to your control in the "Remote diagnostics (RCS)" window.
You set the rights for all remote operating types in this window. The selected rights are defined
from the PLC and using the setting at the HMI.
The HMI can restrict the rights specified from the PLC, but however, cannot extend the rights
beyond the PLC rights.
If the settings made permit access from outside, access also requires manual or automatic
confirmation.
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
However, if the settings made for "Specified from the PLC" and "Selected in the HMI" permit
access from outside, access also requires 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.
If there is no local operation, the control behavior can be set for this particular scenario. You
define for how long this window will be displayed and whether remote access will be
automatically rejected or accepted after the confirmation has expired.
