Parameters
Access Areas (Password Level):
You have to ensure, that the access authorizations are protected by secure
passwords. These passwords have to be kept as a secret and to be known
only by the authorized persons.
A lock symbol indicates in the upper right corner of the display if there are
any access authorizations active at the moment . That means, within the
mode "Read Only Lv0" a closed (locked) lock symbol will be shown in the
upper right corner of the display. As soon as there are any access
authorizations active (above the "Read Only-Lv0" level), the upper right
corner of the display will show an unlocked (open) lock symbol.
During setting parameters the C-Button will be used for the cancelling of
parameter changes. Because of that it is not possible, to acknowledge
(LEDs, Output Relays...) as long as there are non saved (cached only)
parameters.
Acknowledgement can only be executed, when the upper right corner of the
display shows this symbol:
The passwords are part of the device (fixed assignments). That means,
passwords will not be overwritten, if a parameter file is transmitted into a
device.
Existing passwords are persistent (assigned to a device). If an offline
created parameter file is transmitted into a device, or if a parameter file is
transmitted from one device to another, this will have no impact on existing
passwords within the device.
