Pulsed Outputs
The digital pulsed outputs can be used to detect short-circuits and open-circuits on digital
inputs, e.g., on EMERGENCY STOP button complying with Cat. 4 and PL e in accordance with
EN ISO 13849-1.
i
Pulsed outputs must not be used as safety-related outputs (e.g., for activating safety-related
actuators)!
3.4.4
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.
i
Only the model variants without protective lacquer are equipped with a reset key.
The key can be accessed through a small round hole located approximately 5 cm from the
upper left-hand side of the housing. 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 s. 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 connection parameters (IP address and
system ID) and accounts become effective.
Those configured by the user.
Those valid prior to rebooting with the reset key engaged, if no changes were performed.
