Application
This module is used for coupling the PROCONTROL station to
the PROCONTROL remote bus which uses an FDDI ring
(distributed data interface based on optical---fibre technology)
acc. to the ISO/IEC 9314 standard.
The distance between two stations connected to the FDDI ring
must not exceed 2 km.
The overall length of the FDDI ring must not exceed 100 km !
The module also controls the operational activities necessary
for the data exchange within the PROCONTROL station.
Data transfer on the FDDI ring is protected by the generator
polynome specified in FDDI standard ISO 9314.
The PROCONTROL telegrams are provided with a specific
CRC protection and are packed and transferred in FDDI
frames. The hamming distance is d=6.
Features
The module is equipped with
• Two standard interfaces for the station bus,
• One standard interface with the FDDI ring based on ISO/
IEC 9314,
• One interface for dual---channel station ---bus coupling via a
second coupling module,
• One potential---isolated monitoring interface for cabinet
annunciations,
• One test and service interface,
• One potential---isolated input for deactivating the optical
transceivers.

The module uses module addresses 60 or 61 (depending on
whether it is used for single ---channel or dual---channel opera-
tion) and module address 62 (cf. chapter 'Setting the station,
system and module addresses').
It can be plugged into any slot of the PROCONTROL cabinet.
The standard cabinets provide reserved slots.
The coupling module is suitable to be used with 24 V PRO-
CONTROL modules.
Design of the module
The module essentially includes the following functions (cf.
'Function diagram'):
• FDDI system interface
• Station bus interface
• Station protocol control
• Send and receive shared memory
• Setting function for the station and system addresses and
the operating mode
• Monitoring interface
• Interface for dual---channel station ---bus coupling
• Diagnosis and annunciation functions
