Damage of the device possible!
Do not exchange the terminals L+ and L-, or connect them to other terminals of the
device!
In case of a false connection, a pre-fuse blows to prevent the device from being
damaged.
7.2.8
Using the Reset Key with the CPU 01 and CPU 03 Modules
The modules are equipped with a reset key. The key is only required if the user name or
password for administrator account is not known. If only the IP address set for the controller
does not match the PADT (PC), the connection can be established with a routing entry on the
PC (
Route add
command).
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.
The reset is only effective if the controller 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.
NOTE
Fieldbus communication may be disturbed!
Prior to switching on the controller with the reset key engaged, unplug the controller's
fieldbus connectors to ensure that the fieldbus communication among other stations is
not disturbed.
The fieldbus plugs may only be plugged in again when the controller is in the RUN or
STOP state.
Properties and behavior of the controller after a reboot
with
engaged reset key:
Connection parameters (IP address and system ID) are set to the default values.
Only the Administrator default user account with an empty password exists.
With COM operating system V10.42, loading a user program or operating system with
standard connection parameters is inhibited!
The loading procedure is only allowed once the connection parameters and the account
have been configured on the controller and the controller has been rebooted.
After a new reboot without the reset key engaged, the following applies:
The user-defined connection parameters (IP address and system ID) and user accounts are
effective.
If no changes were performed, the connection parameters and accounts that were valid prior
to the reboot with the reset key engaged, apply.
