ZENNIO LINECOUPLER AS A REPEATER
Figure 2 also includes a particular case where a repeater (marked as “LR”) is required:
two separate sub-line segments (one of which with no other connection to the
installation, in order to prevent forbidden situations such as in Figure 7), both
containing devices, need to be linked for extending the sub-line. Linecoupler offers
such linking interface, with proper electrical insulation for the connections.
Figure 7
Forbidden Situation: Segment with Two Connections to the Bus
Line repeaters do not implement filter tables
. As the name suggests, any telegram
on one of the buses will be repeated to the other bus. It is therefore irrelevant whether
the telegram originates on one side or another and whether it is destined to one side or
another: both segments melt together. Therefore, the Linerepeater application program
will only let transmitting or dropping every telegram destined to physical addresses,
while no drop or filter options are provided for those destined to group addresses.
Note
:
while the individual address of a line coupler does, the individual address of a
repeater does not have particular restrictions, apart from belonging to the address
range of the corresponding sub-line
.
In the case of the line repeater application program, the LED lights on the top of the
device follow the pattern already described for the line coupler application program
(see section 2.1.1), although the GA status LED will always show in orange (no option
for group address blocking or filtering is available in the line repeater), while the PA
status LED will never turn green (no option for individual address filtering is available in
the line repeater).
