Safety Device Diagnostics

Safety Device Diagnostics is an option that can be selected independently of the safety-re-
lated wiring.
When using the Safety Device Diagnostics, up to 16 sensors can be connected as a sub-
scriber to a fieldbus module.
The communication of the sensors with the fieldbus module is automatically built up again
with each new supply of the supply voltage. As a result, a sensor can be exchanged, e.g.
when servicing, without the need for special measures.
An exchange can be detected via the fieldbus module e.g. through the serial number.
} With Safety Device Diagnostics there are the following diagnostic options for the fieldbus
module:
– Poll information of the sensors (examples: what sensor in the series has switched, at
– Read configuration parameters of the sensor (examples: Number of teach-in pro-
– Perform actions (example: poll updated actuator name)
– Selectively activate or deactivate guard locking of individual PSEN ml within a series
The results of the sensor diagnostics can be checked already during the installation phase
via the display in the fieldbus module, without the need to connect the fieldbus module to
the network.
}
With Safety Device Diagnostics there are the following diagnostic options for the fieldbus
module for simple wiring:
– Information is passed on via the fieldbus module directly to the network
– Mappings of the signal outputs to the sensor are automated by the SDD.
This prevents wiring errors and an expansion or reduction of the sensors is possible
without the need to change existing wiring.
– Wiring in accordance with IP20: Rapid installation in the control cabined is enabled.

Operating modes

The safety switch can be used in various operating modes.
}
Operation without safety device diagnostics
– Standard operating mode
– No communication with Safety Device Diagnostics
– Activating/deactivating the guard locking is only via the signals S31 and S41
} Operation with passive use of the Safety Device Diagnostics
– Safety switch supplies diagnostic data to Safety Device Diagnostics
– Activating/deactivating the guard locking is only via the signals S31 and S41
