Table 44: Legend for the iPar Server Figure

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-device (Prm_Telegram)
6 Message to iPar server via diagnostic agent (alarm/status)
7 iPar server polls Diag FB and starts "Save" if required
8 iPar server polls Diag FB and starts "Restore" if required

Default Value Explanation
No Check
SIL 3
4-byte CRC
1
The F I/O module only supports PROFIsafe
mode V2. The parameter is not evaluated and
must be set to "No Check."
For the F I/O module, this value must always
be set to "No Check."
The F_SIL parameter specifies the required
safety integrity level of the F I/O module. The
F 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 CRC2 key to be used in the
PROFIsafe telegram. The F I/O module only
supports a 4-byte CRC. This value is specified
by the WAGO device description file
(GSD/GSDML).
The F_CRC_Seed parameter defines the
calculation type of the CRC2. This value is
specified by the WAGO device description file
(GSD/GSDML).
