Then adjust the F parameters of the PROFIsafe I/O module by setting the
F_iPar_CRC in the hardware configuration environment to the value from the
WAGO parameterization tool. You have to recompile the hardware configuration
and the safety program and transfer it to the safe PLC.
If you have correctly set the F_iPar_CRC in the previous step, there is a match
with the iPar_CRC persistently stored in the PROFIsafe I/O module. The current
iParameters of the PROFIsafe I/O module are then transferred to the safe PLC and
permanently stored, so that an I/O module can be replaced, for example, in case of
maintenance without new parameterization.
You have to observe the listed required workflows within the respective
manufacture documentation, as well as check and document all safety functions.
7.5.3
PROFIsafe I/O Module with iPar Functionality without iPar
Server
To use the PROFIsafe I/O module with iPar server functional but without using
the iPar server, select the I/O module with the “75x-666 4FDI/2FDO iPar-Server”
designation from the device catalog and add it to the fieldbus node. Without using
the iPar server, the F_iPar_CRC is only checked against the iPar-CRC by the
PROFIsafe I/O module. Thus, it is permissible to operate the PROFIsafe I/O
module without password protection for the iParameters.
Behavior of the PROFIsafe I/O module when discrepancies occur between
F_iPar_CRC and iPar-CRC!
If the PROFIsafe I/O module identifies a discrepancy between the F_iPar_CRC
and the iPar-CRC, substitute values (failsafe values) are output instead of actual
process values by the PROFIsafe I/O module.
After you have configured the PROFIsafe I/O module, create the required call
structure for the safety program. The required system calls and system settings to
activate the safety program are added to the project.
Then configure the PROFIsafe I/O module using the WAGO parameterization
tool (see the section "Parameterization of the PROFIsafe I/O Module with the
WAGO Parameterization Tool"). The WAGO parameterization tool displays the
iPar_CRC. You have to note this for the next step (e.g., copy to the clipboard).
Then adjust the F parameters of the PROFIsafe I/O module by setting the
F_iPar_CRC in the hardware configuration environment to the value from the
WAGO parameterization tool.
