4.6.1 Reset
4.6.1.1 Model Description
A service to reset the communication components (FMS, LLI, FDL, PHY, FMA1/2 and
FMA7) is provided to the FMA7 user.
4.6.1.2 Services
The FMA7 Reset service is mandatory.
4.6.1.2.1 FMA7 Reset
With the FMA7 Reset service the complete communication, i.e. FMA7, FMS, LLI,
FMA1/2, FDL and PHY, is reset. The restart after a reset is performed in the
same way as after a POWER ON. FMA7 transfers a Reset.req primitive to FMA1/2,
LLI and FMS after obtaining a FMA7 Reset.req primitive. After obtaining all as-
sociated confirmations, FMA7 transfers a FMA7 Reset.con(+/-) to the user. FMS,
LLI, FMA1/2, FDL and PHY conduct a restart after the reset.

4.6.2.1 Model Description
A service which indicates events and faults in LLI, FDL and PHY is provided to
the FMA7 user.

PROFIBUS-Specification-Normative-Parts-7:1997
Copyright by PNO 1997 - all rights reserved
4.6.2.2.1 FMA7 Event
Events and faults which occurred in the LLI, FDL or PHY are notified to the user
with the FMA7 event service. The FMA7 does not perform fault handling.

Argument
The argument contains the parameters of the FMA7 Event.ind primitive.
Communication Reference
This parameter specifies the identifier of the associated communication rela-
tionship. If the FMA7 Event.ind cannot be assigned to a communication reference,
then the value NIL is given.
Instance Identifier
This parameter indicates in which instance the fault or the event occurred.
Valid values
- LLI
- FDL
- PHY
Event/Fault
This parameter specifies the event or the fault. If the parameter Instance Iden-
tifier has the value LLI, then the meaning of the parameter Event/Fault shall be
found in Table 111 Reason Codes for LLI Fault.ind.
If the parameter Instance Identifier has the value FDL or PHY, then the meaning
of the Event/Fault shall be found in part 3.
Additional Detail
This parameter contains additional information on the corresponding event or
fault. If the parameter Instance Identifier has the value LLI then the meaning
of the parameter Additional Detail shall be found in Table 111 Reason Codes for
LLI Fault.ind (tag: AD).
If the parameter Instance Identifier has the value FDL or PHY, then the meaning
of the parameter Additional Detail shall be found in the Data Link Layer (Event
FMA1/2) of the PROFIBUS Specification.
