No. Explanation
1 Instantiation of the iPar Server function
2 CPD Tool Start and parameter transfer (e.g., node address)
3 Parameterization of iParameters of a F I/O module and commissioning
4 Transfer of iPar signature (CRC over the iParameters) to the F-Host
5 During startup, transfer of the iPar signature to F-slave (Prm_Telegram)
6 Message to iPar server via diagnostic agent (alarm/status)
iPar server polls Diag FB and starts "Save" if required

Use the application notes from WAGO!
An overview for using the F I/O module in combination with a safe PLC is
summarized in an application note. This application note is available on the

Overview of PROFIsafe F Parameters

Table 57: PROFIsafe F Parameters

F parameters
F_Check_SeqNr No Check
F_Check_iPar
F_SIL
F_CRC_Length
Default
Description
Value
The F I/O module only supports PROFIsafe Mode
V2. The parameter is not evaluated and must be
on "No Check".
For the F I/O module, this value must always be
No Check
set to "No Check".
The F_SIL parameter specifies the required
safety integrity level of the F I/O module. The F
SIL 3 I/O module supports SIL3. This value is specified
by the WAGO device description file
(GSD/GSDML).
The F_CRC_Length parameter specifies the
length of the CRC 2 key to be used in the
PROFIsafe telegram. The required length
depends on the length of the user data to be
transferred.
Valid combinations are:
3-byte CRC
F_CRC_Seed,
F_Passivation
0, 0
(PROFIsafe V2.4)
1, 1
(PROFIsafe V2.6)
Version 1.0.0, valid from HW/SW Version 01/01
