is assigned by the configuration tool
Default Value Description
The F_WD_Time parameter determines the
monitoring time for PROFIsafe communication
between F controller and PROFIbus I/O
module.
At least one valid PROFIsafe telegram must
be exchanged between the safe PLC and the
F-I/O-module within the monitoring time.
If this condition is not met, the safe PLC or F-
150 I/O-module initiates a safe state.
The monitoring time must be selected, so that
telegram execution times are tolerated, but an
interruption in the connection is detected
quickly enough.
The monitoring time can be specified in steps
of 1 ms. The possible value range
(50 ... 10000 ms) is specified by the WAGO
device description file (GSD/GDML).
The F_iPar_CRC is only available when
F_Block_ID = 1 and specifies a comparison
value for the CRC value via the individual
Parameter (iPar_CRC). The PROFIsafe data
exchange only starts when the values for
F_iPar_CRC and der iPar_CRC match. If they
differ, the F-I/O-module makes a restore
request of the individual Parameter from the
12668
iPar server.
(0x317C)
The F_iPar_CRC value "0" holds special
standing. This value switches the PROFIbus
I/O module into test mode.
The CRC value (iPar CRC) is displayed by the
WAGO parameterization tool and must be
transferred with the configuration tool of the
safe PLC to the F parameter of the F-I/O-
module.
