3.5.3 Reset Key
The remote I/O 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 remote
I/O 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 approximately 5 cm from the
upper left-hand side of the enclosure. The key is engaged using a suitable pin made of
insulating material to avoid short-circuits within the remote I/O.
The reset is only effective if the remote I/O 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.
Properties and behavior of the remote I/IO after a reboot with engaged reset key:
Connection parameters (IP address and system ID) are set to the default values.
All accounts are deactivated except for the default account administrator with empty
password.
After a new reboot without the reset key engaged
the user-defined connection parameters (IP address and system ID) and accounts
become effective.
no changes were performed, and the connection parameters and accounts valid prior to
the reboot with the reset key engaged still apply.
