Manual
Version 1.2.0, valid from HW/SW Version 01/01
In this output configuration, the PROFIsafe I/O module switches both
semiconductor switches ON or OFF at the same time using the bit 0 of the output
process image.
If you want to disable line break detection for the load, set the
Line break
detection
parameter to "inactive". Otherwise, set the Line break detection
parameter to "active" so that the PROFIsafe I/O module performs the line break
detection task once per minute.
For more information about configuring the PROFIsafe I/O module, read section
"Parameterization of the PROFIsafe I/O Module with the WAGO
Parameterization Tool".
Please note that line break detection may not be part of the safety function under
any circumstances.
You can achieve a risk reduction of SIL3/Cat.4/PL e, for example, by reading
back the switching states of the power jumper contacts from positively driven
contacts of a relay.
Line break detection on the digital output
You must use the
Line break detection
parameter in the "H-Side/L-Side 1"
output configuration
to monitor line breaks between connections O1B or O2A to
the connected load.
Line break detection is not safety related and cannot be part of the safety function
under any circumstances.
Use the same value for the output tolerance time of output O1 and O2!
If the
Output Configuration
parameter is set to "H-Side/L-Side 1", the values of
the
Output tolerance time
for both outputs O1 and O2 must be set to the same
value. This is checked by the PROFIsafe I/O module during the parameterization
procedure and a suggested correction is indicated by the PROFIsafe I/O module in
the WAGO parameterization tool in case of deviation.
Use the same value for the test pulse duration of output O1 and O2!
If the
Output Configuration
parameter is set to "H-Side/L-Side 1", the values of
the
Test pulse duration
for both outputs O1 and O2 must be set to the same
value. This is checked by the PROFIsafe I/O module during the parameterization
procedure and a suggested correction is indicated by the PROFIsafe I/O module in
the WAGO parameterization tool in case of deviation.
