Setting remote access

You can influence the remote access to your control in the "Remote diagnostics (RCS)"
window.
Here, rights for all types of remote control are set. 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, then this is still dependent on a manual or
automatic confirmation.
Rights for remote access
The "Specified from 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
The combination of the settings in the HMI and in the PLC show the valid status as to
whether access is permitted or not. This is displayed in the "Resulting from" 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.
