3.4.8 Reset Key
The device is equipped with a reset key. The key is only required if the user name or
password for administrator access is not known. If only the IP address set for the device
does not match the PADT (PC), the connection can be established with a
Route add
entry
on the PC.
The key can be accessed through a small round hole located on the front plate. The key is
engaged using a suitable pin made of insulating material to avoid short-circuits within the
device.
The reset is only effective if the device is rebooted (switched off and on) while the key is
simultaneously engaged for at least 20 seconds. Engaging the key during operation has no
effect.
WARNING
Caution! Fieldbus communication may be disturbed!
Prior to switching on the device with the reset key engaged, all device fieldbus
connectors must be unplugged to ensure that the fieldbus communication among
other stations is not disturbed.
The fieldbus plugs may only be plugged in again when the device is in the RUN or
STOP state.
Properties and behavior of the device after a reboot with engaged reset key:
ƒ Connection parameters (IP address and system ID) are set to the default values.
ƒ All accounts are deactivated except for the administrator default account with empty
password.
ƒ With COM operating system version 10.42 and beyond, loading a user program or

After a new reboot without the reset key engaged, the connection parameters (IP address
and system ID) and accounts become effective.
ƒ Those configured by the user.

performed.
