Mode of Operation
The Optolink is used for one
of the following 3 purposes:
1. Dupline
LAN-Ring with
Computer Interface
In the majority of applications
the Optolink is used to build
up a local area network of up
to 63 Dupline
systems. With
this a maximum of 8064
Dupline
channels may be
controlled and monitored by a
computer. The LAN-ring is
created through fibre optic
cable with a maximum dis-
tance of 50 m between
Optolinks. The connection to
the computer is established
by means of the interface G
3491 0090. Each Optolink is
set up for a unique device
number between 01 and 63
while the computer is device
number 00. The computer
can read/write data from/to
individual Optolinks by refer-
ring to the device numbers.
For protocol and communica-
tion information please refer
to the data brochure DAT OPL
ENG.
2. Split of a Dupline
System
In case of Dupline
routing
through areas with high elec-
tromagnetic interference or
through potentially explosive
areas the signal transmission
is to be done via fibre optic
cabling. The great advantage
of this is that optical transmis-
sion is totally immune to elec-
trical and magnetic distur-
bance. For this application a
Dupline
system is split into
two systems with one
Optolink each. The connec-
tion be-tween the two sys-
tems is done by fibre optic
cables. Here both Optolinks
must be set up for device
number 00. Establishment of
commu-nication is automatic
and no other adjustments or
soft-ware is required by the
user.
3. Dupline
System Distan-
ceIncrease
If Dupline
is used in very ex-
tensive applications where no
other means of communica-
tion, e.g. telephone line is
available, several Optolinks
may be daisychained.
If, for instance, two Dupline
systems are connected via
Optolink the distance is dou-
bled (2 x 10 km). The proce-
dure and set-up is the same
as under 3 above but it
should be noted that the
reaction time per pair of
Optolinks increases by app.
0.45 s.
