Using Fail-Safe I/O Modules (PROFIsafe V2)
The fieldbus coupler allows you to operate all PROFIsafe V2 I/O modules of the
750 and 753 series with the respective item number extension ".../000-003".
This extension indicates that it is a 3rd generation PROFIsafe I/O module.
You can activate diagnostics channel-by-channel using the fieldbus coupler
750-375. Module diagnostics, e.g. F parameterization error or iPar client message,
are activated globally.
The submodules of the PROFIsafe V2 I/O modules allow storage of module-
specific parameters, i.e., safety-related parameters (iParameters) on an available
iPar server of the higher-level control.
That is a significant advantage when a module has to be replaced. Initially, the I/O
module just installed has the default settings. The previously saved individual
parameterization is automatically set via the non-secure functionality of the
respective iPar server function block. This ensures that productive data exchange
can be included again immediately after the exchange.
In the event that no iPar server is available or you want to operate the PROFIsafe
V2 I/O modules using the factory default parameterization ("out of the box"), the
"F_iPar_CRC" of the submodules are already preset with values in the GSD file.
These values correspond to those of the factory settings. Use of the WAGO-SEDI
is thus not required.
More Information on the PROFIsafe V2 I/O modules!
More information on the PROFIsafe V2 I/O modules is available in the respective
manuals of the PROFIsafe safety modules of the 750 and 752 series. You can
download these manuals free of charge from the WAGO Internet site at:

Individual Parameterization of I/O Modules via
iPar Server
The iPar server provides services for saving and restoring iParameters for quick
device replacement without using additional manufacturer tools for
parameterization of device functions.
The iPar server is a function block or available as a system function within the
non-safety related part of the safe PLC.
Currently, you can only use the iPar server mechanisms with the PROFIsafe V2
I/O modules.
To parameterize device functions of these I/O modules, the iParameters are used
that have to be set at start-up using a manufacturer tool due to the current
definitions.
